General Announcement:
- A. Galler reminds the attendance that this meeting is also an opportunity for making comments/questions on the new Covid-19 rules that start to take place.

CTRL:
- Main issue last days was related to the SA3 VAC PLC. The applied fix was left running during the weekend. So far it works faster and reacts faster for diagnostics. 
CTRL is getting some statistics in order to get the final solution. If something goes wrong, please call OCD.

- No OCD calls during the weekend.

DA:
- No issues or news.

EEE:
- uTCA crate of SA2 balcony room is not reachable. A quick fix on Friday was not successful and EEE needs to power cycle or replace the whole crate. 
This will interrupt timing for PP-laser and the signals sent to MPS. Meeting between EEE, lasers, instruments and XO will take place. 
- (Note after meeting: the power cycle of the actual crate will be done today after lunch. If this does not helps then immediately exchange of crate will be done 
afterwards. 
PP-laser will be brought to a safe state and takes about 4-5 hours to restart it).

VAC:
- Nothing to report.

XPD:
- Worked at BKR with MCP detectors. XPD reported to CTRL an issue with ADC - some channels see no signal or not standard ones.

CTRL:
- SA3 vacuum loops problems: seems to compromise some experiments. Beckhoff loops are changing states very quickly and compromises the whole system. 
CTRL ask for the instruments to give info on the type of command given that makes motors change states. CTRL investigates together with EEE as more data has been produced 
as compared to the past. 
This problem does not happen in SA1/SA2 and may be related to the PES which will be checked this afternoon.

- The Winter maintenance period was adjusted yesterday. The ending period is now on January 13th, 2021, instead of January 4th. 

CTRL:
- CTRL is reaching conclusions on recent Beckhoff problems: 
1. CTRL would like to upgrade most of installations in instruments next week (upgrade of motors software). This upgrade is in general a step forward for the PLC 
connections when it is dropped (re-starting). 
2. For SASE installations, CTRL will make next week during machine days. 
3. The GATT will not be upgraded now – this will start during Winter maintenance period. Upgrade of GATT is a priority for CTRL (has been added to the maintenance list 
submitted to XO). 

DA:
- Nothing to report.

EEE:
- Intervention in SA3 PP-laser was done.

VAC:

Maintenance" to avoid confusion among the staff. 
The tasks list shall be sent to xo-planning@xfel.eu. 
- In case of need to go to tunnel via ZZ, please contact the PRC at 9-4800.
- Gerd W. informs on the SXP construction work that starts on Nov. 23rd. The plan aims for a minimal impact in SA3 area at XHEXP1. 
There will be new connections to the cooling water system in SA3and civil constructions. 
Cooling water will be cut from Nov. 23rd until Christmas. This means rack rooms and laser will be affected. 
- Gerd W. answers Raul V.: the cut cooling water supply does not involve tunnels. 
- Tommaso M. says instruments need to have permanent cooling water supply. 
Gerd W. states the electronics must be shut down and will not be able to re-start before Christmas as it takes time to empty the system, weld, do pressure tests and fill 
it up again. 
- XO suggests that SA3 instruments must coordinate closely with Gerd and also involve MB (Serguei M.).
- Nerea J. asks if this applies to SA3 balcony room also. Gerd W. says that the rack rooms will be affected. 
- Gerd informs there is a series of meetings taking place on Thursdays at 14:00 and this construction work can be addressed. The SCS and SQS group leaders have been 
invited to this series. 
If someone else wants to participate, please contact Gerd W. for getting the Zoom link, 
- Monica T. says that this lack of cooling water may impact the DSSC move to SQS by delaying its test.

affect devices until the fix is done.

DA:
- Train-ID investigation for AGIPD offset is ongoing.  DA understands from now on DET is responsible for the leading efforts. 
- Monica T. comments it has been identified the issue related to the AGIPD firmware (2019 version, accordingly to Jolanta). This will require a significant change and to 
do it now is not an option. 
The good news is that this is a systematic issue and DET know how to take care of it.

- There is a problem with SASE2 online data storage. It happens data were not migrated from Schenefeld to Desy or it was very slow which in turn affected MID. Partially 
solved by making system live. 
- ITDM needs to diagnose the GPFS filesystem in SASE2 in order to understand the issues we experienced over the weekend. This may lead to some instabilities or even 
unavailability of the SASE2 online data storage. 
- XO suggests ITDM to coordinate separately with MID and HED.

XRO:
- Nothing to report.

LAS:
- SA3 had power drops and today LAS makes tests regarding Daniel Rivas info.
- SA1 currently replacing laser diode and updating uTCA system.
- SA2 nothing to report.

UNSYS:
- Terminals for SA2/cell31 have arrived and are ready to be installed in next ZZ access.
- Problem with air coil in SA3/cell12 this morning will be taken care.

SPB:
- Commissioning last week using 5 keV beam.

FXE:
- Mono commissioning.

MID:
- Recovered vacuum issue on cryocooler on SAT morning with help from TS. Beam was back on Saturday morning (+-10AM).
- Timing tests were running on Friday by EEE. MID waits for results to be analyzed. Train-ID issue seems to be progressing and many people work on it.

HED:
- User beamtime was very successful. Stability was very good.
- Pulse on demand test aimed to be able to have single PP shot synchronized with FEL. Today from 10AM CTRL and LAS will temporarily change bunch pattern (communicated to 
the PRC). 
No need for X-ray beam to the hutch.

SCS:
- No special issues to report.

SQS:
- Two weeks ago the monochromator was used. X-ray beam was twinkling and not reproducible. Seems to be connected to higher heat load when using 300 pulses. 
SQS says that this needs to be addressed when beam is back again.

General Announcement:
- Yesterday evening a ZZ in XTD10 was planned but it turned unsuccessful due to no access in the turnstiles. D3 solve the problem in the middle of the night and since 
then ZZ is possible again.
- Eric Boyd mention on the SQS shutter: a XTD10 ZZ was planned for 8:30AM. He has currently no news so far.

CTRL:
- XGM Pulse pattern decoder issue is under investigation.
- Vacuum issues (giving unknown state in Karabo): also under investigation.
- Next Monday CTRL plans to update Karabo login system. Groups shall inform CTRL if there is any issue against this.
- Last Influx training will be next Friday An e-mail to participants will be sent. 

DA:
- No issues to be reported.

EEE:
- SA1/ Solid Attenuator Interlock problems: EEE is investigating and news will follow. FXE found an issue within the motion loop last night and XRO also helps. 
It is the Interlock on the attenuator itself and not in the EPS.

VAC:
- Nothing to report.

XPD:
- XGM signals were monitored when SA1 went to 5keV for a short time yesterday night. No issues were observed.

DET:
- SCS made an OCD call on the DSSC which has been fixed.
- Agipd issue: under investigation together with ITDM (a ticket was opened to ITDM). This is not a calibration issue. 

ITDM: 
- ITDM will follow on the Maxwell issue with Agipd. 
- CTRL and ITDM working and progressing on the bunch patter issue.

XRO:
- Issue with SA1 solid attenuator: same behavior can be expected also in SA2.
- Mirror inspection in XTD2: it shows no big damage on it. A full service will be made later. Next Monday inspection on XTD10 mirror to understand situation.
- Meeting to investigate possible upgrades to drive motors faster will take place. Participation of CTRL, DA and instruments.

LAS:
- Nothing to report.

UNSYS:
- Suren K. informs Beckhoff Hardware for cell#31/SA2 was received and is under test. As soon UNSYS is ready for a ZZ it will inform PRCs for scheduling a date. 
Mostly likely ZZs will occur on Tuesday and not Monday due to continuation of 11.5 GeV studies. 
- Communication problem with one undulator on Monday was quickly fixed.

SPB:
- Working on nano KB mirrors.
- 5 keV last night: gives right trajectory. It looks like the beam performance was sufficient for SPB alignment. Fine tuning has to come.

FXE:
- Affected by the shutter problem during the tentative ZZ access yesterday.
- Solid Attenuator issue in discussion with EEE.
- Sampling rate of ADC has changed. Peter Z. contacted EEE and it has been accessed.

MID:
- Not present.

HED:
- User experiment ongoing.
- Some stages worked intermittently and has to be investigated (related to crystal alignments).
- Pulse picker is not behaving correctly. It may be a Hardware issue and has to be investigated. Then HED will communicate to EEE.

SCS:
- PP laser was down last night and the OCD was contacted. There is the suspicion the crystal is damaged and the OCD informed it will be fixed this morning. 
Daniel Kane will try to get some info inside LAS and report back t SCS.

SQS:
- It has users this week and shutter becomes a serious issue. In Karabo the shutter state changed but it is disconnected. It is not clear if the ZZ team is progressing 
right now.
- Problem is that when trying to close the shutter via JDDD interface it went to an intermediate state but shutter did not close. 
This cause interlock not opening the hutch and the beam could not be sent to the hutch. No beam since 5PM yesterday. Also locally operated in the panel it does not work. 
The JDDD interface worked nicely the whole last week. Eric Boyd asks if problem appeared at the first operation. Tommaso M. says they did a lot of times prior having this 
issue.
- Waiting for updates from CTRL mentioned.

General Announcement:
- None.

CTRL:
- CTRL will deploy an update on time server configurations for SA1 and SA3. Bunch time decoders will be down during few minutes.
- SPB and SQS reported during the weekend they do not have pulses per train correctly presented. This relates to the update on server configurations. CTRL is looking into 
it with SPB today.

DA:
- Minor OCD calls during the weekend with no severe issues.

EEE:
- EEE works with SPB on configurations of motors (in general with several other instruments).
- Looking into XPD issues.

VAC:
- It notices quite often one has to restart C++ servers due to communications issues. CTRL and EEE are investigating: it does lose connection and then does not properly 
restart. 
PLC continues running in the background. CTRL recommends restarting CPP server as workaround. 

XPD:
- XGM in SA3 shows not accurate number of trains per pulse. First pulses of a train were missing. It will be followed up with CTRL and SQS.
- There is an agreement in how to enable the 5keV operation. Instruments shall be aware of ahead planning when changing photon energies (band region of resonances which 
requires exchange of gases). 
In general SA1 and SA3 instruments are aware.

DET:
- Working on calibration issues.
- Problem from SCS with Karabo device going in unknown mode has been under investigation.

ITDM: 
- Comment to DET: it has been understood issue with Maxwell nodes last week - jobs running and certain nodes were in bad state. It was a particularity of the 
configuration. This affected the calibration. 
- Bunch pattern issue: we were communicated around 2AM on an issue that data recording was not the same as the scene. ITDM asks for communication of major issues must be 
done in earlier times when experts are around. 
XO will talk with CTRL and ITDM, as well as SQS.
- exfelgateway and Karabo installation: we will move today the installation. Link will redirect to the next location. No changes in how to start Karabo GUIs.
- Tomorrow a maintenance affecting Oracle databases will take place from 7AM to 1PM. For example, DACHS/DARF, UPEX will be down.

- Problems with SA1/cell7 yesterday have been fixed.

SPB:
- Hardware exchanged late Friday and during weekend.
- Bunch pattern recording issue was discussed with CTRL last week during the day. It is of importance to correlate the data with number of bunches.

FXE:
- Minor issues with components motors: when pressed step up /step down in the motor, the Karabo interpret that we pressed twice. It is not critical but annoying. Issues 
are related to MC2 motors. 
CTRL will get in touch with EEE in an offline discussion. Issue has a different nature compared to the HED problems with motors.
- Tests on Monochromator show energy drifts. For long range scans one has to correct manually the calibration. FXE will report to CTRL today or tomorrow.
- Friday beam instability due to horizontal jitter: FXE took some data and will communicate. 

MID:
- Number of bunch train issue was also observed.
- Train IDs going to AGIPB are correct and verified.

HED:
- CRL must be investigated (motors). It moves one way but not for backwards.
- We made a ticket for Mono1: problem came up again during the weekend.
- EEE wants to make uTCA installations (after HED request) on next Tuesday. HED and EEE will discuss a suitable time together.

SCS:
- Issue with DSSC mentioned by DET.
- Nothing else to report.

SQS:
- Issue in past weeks: shutter does not respond but it seems to be working now. F. Wolff-Fabris will ask the Desy colleagues for an update on the situation.

General Announcement:
- XO reminds the groups to please inform staff to check for self-rescuer training date in the DACHS system. In case this is expired please contact Michael Prollius or SRP 
group.
- Martin Dommach informs fthe access rights to the photon tunnel and accelerator has also expired for several people in August. Please check that.

CTRL:
- Yesterday evening XPD informed on an issue with Karabo GUI for exflgateway. It has been under work. LAS has a work around. CTRL encourages to do not work until it is 
fixed (likely in the next 30 minutes).

DA:
- Nothing to report.

EEE:
- Nothing to report.

VAC:
- Nothing to report.

XPD:
- All is fine. XPD asks CTRL to please send instructions to bypass the Karabo GUI issue mentioned by CTRL. CTRL says it will be fixed in next 30 min.

DET:
- OCD call yesterday has been solved. 

ITDM: 
- Video conferencing system is on the HED control room and under test.

XRO:
- Maintenance in SA1/M3 mirror for Tx spindle took place on Monday as a ZZ. Mirror/spindle seems fine and we did maintenance without affecting mirror position or 
settings. 
XRO waits for spare parts to be delivered for additional maintenance.

LAS:
- SA1 and SA3 lasers are in operation; SA2 laser is in maintenance.

UNSYS:
- Problem with SA2/cell31 is serious: the complete bus terminals are damaged in the rack. Currently SASE2 works up to cell 31.
- New set of terminals is needed from Bekhoff to replace the full instance of the rack. Suren K. will inform on updates/status and when parts arrive for asking tunnel 
access. 
The old ZZ request is still valid. Order will be placed soon and Beckhoff promises delivery in one day after receiving order. 

SPB:
- Minor Problem with one motor but it is under investigation. 

FXE:
- Problem with a motor: EEE is informed and today they will check it.
- Andreas G. asks if FXE sees changes on mirror positions due to Monday maintenance. Martin K. will inform the group to verify during the night shift.

- Not present.

HED:
- M3 re-alignment is very good. HED get the first Mono aligned and continues today with preparations/alignment. 
- Thomas Preston says issues with a motor stages is under investigation (it worked in the past).

SCS:
- Yesterday morning machine had tuned beam to SCS photon energies. Somewhere this has been lost and SCS and BKR had to do it again on the afternoon. PRC will investigate 
with RCs.
- Smaller issue: For 2x already there is an issue with pulses that DSSC send to online read (sometimes we get only 8 pulses). 
DA states it is related to the calibration pipeline when this is reset (default is 8). 
One has to change/correct manually in the config manager. DET asks SCS to place a ticket for the support. 
SCS plans to use DSSC for user experiment this week. It is not critical issue but it would be nice to fixed for once.

SQS:
- Preparing for user's time on next week. SQS has commissioned the Monochromator with grating for the first time.

Instruments that are willing to help with the test can contact ITDM. The idea is to test in a Linux machine and test with remote users. SQS and HED are initially 
interested. 

XRO:
- Not present due to M3/SA2 re-alignment.

LAS:
- SA2 updates must be done by the end of today.
- SA1 and SA3 must be operational by the end of the day.

This is also valid for changes of beam parameters if not previously reported in the operation tables. 

CTRL:
- CTRL is supporting the ongoing Laser installations. 

DA:
- Nothing to report.

EEE:
- Fast ADC in HED: this is solved. The only limitation is if the system is restarted the ADC is misconfigured. In this case please inform EEE for loading the 
configurations.

- Nothing to report.

DET:
- Nothing to report.

ITDM: 
- No big announcements at this moment.

XRO:
- M3 mirror: mechanical axis was disconnected and mirror was not moving. XRO and VAC fixed the problem. Hopefully beam can be injected to XTD6 this afternoon. 
- It was chosen not open the full chamber to make the repair in 2 days' time. As beam is there XRO will re-align mirror. Cooling system is disconnected.
- After closing tunnels, it will allow beam in MID certainly and to HED we will look after the re-alignment of the mirror (to be scheduled). Maurizio V. is open to 
clarifications/discussions.
- Ulf asks on the plans for re-alignment of the beam: Maurizio says either after the Self-seeding on Friday or on Monday.

LAS:
- Upgrades are ongoing in all lasers: a bit behind schedule.
- SA1: ADC has to be serviced by EEE; SA2: delays due to microTCA.
- SA1 and SA3 shall be available tomorrow afternoon.
- Tests with HED laser pattern on demand: LAS demands to be included in discussions for October use of PP-laser. Synchronization must be developed to run properly.  LAS 
can't guarantee it will work from the first try.
- Cw37: SCS needs laser, as well as MID has preparations. LAS states both lasers shall be back in operation on THU afternoon shall be available.

- SCS/XGM presents issues with interlocks being activated due to pressure levels. This required intervention from expert. 
If this happens in the middle of the night, SCS proposes to develop an automated way to reset it or to be trained by XPD experts. XO, SCS and XPD will follow up. 
- Extra-foam: SCS asks on the possibility for access to remote users. DA says is under discussion between DA and ITDM to extend the service but no decision has been made. 
It will anyway need access to online clusters.  

SQS:
- Not present.

General Announcement:
- XO reminds every day at 15:00 there is an informal BKR chat where one might get interesting news and ideas. If you would like to join, the link appears in the BKR e-
log.
- K. Wrona asks instruments if there are things to be improved regarding remote user communication or process, please send suggestions and/or comments to him/ITDM.

CTRL:
- Electronics team is installing new digitizer with LAS group.

DA:
- Nothing to report: OCD was quiet during last week.

EEE:
- Fast ADC system issues: problem with HED hutch. Signals were not properly given due to wrong configurations. It has been solved.
- All XPD systems had same issue: last Karabo update had a default address wrongly set and was the cause for reading wrong numbers. 
This was solved with help of CTRL but one crate remains to have the ADC card re-started, probably today. 
- SCS auto scanner: suspicion links to the loop that runs the motor is not fast enough.
- SCS and SQS have cabling installations planned for this week.
- Theo M. asks which ADC had a train-ID issue. Patrick G. answers that looks the XTD10, crate 3.2. It has been taken care already.

VAC:
- PRC contacted VAC on Thursday with XGM in XTD1: faulty pump that survived the weekend. VAC will exchange it today.
- HED problems with M3: VAC and XRO are working on it now and it probably to exchange an spindle or mechanical structure.
- SCS GATT stopped working on Saturday: power glitch caused a long shutdown of cooling water that switched OFF pumps and GATT.

XPD:
- Restarted XGM; also SCS XGM had a faulty gauge.

DET:
- Nothing major: Detectors were working during the weekend.

ITDM: 
- Not aware of any major issue.

XRO:
- M3 issue: mirror looks fine but the mechanical structure to move the mirror horizontally failed. Mirror surface looks mostly fine, only one InGa drop is seen. 
XRO and VAC are in tunnel to try to make it a fix now. There may be also a problem with Platinum coating if drops of InGa are on it.

LAS:
- SA1 laser will be down for the entire week for exchanging parts.
- SA2 laser uTCA update today: shall be back on Tue/Wed;
- SA3 laser issues with Amphos are being exchanged/fixed. Probably by WED afternoon this laser is back.
- Upgrade of control PCs ongoing this week.
- LAS states SA3 laser is planned to be available tonight.

UNSYS:
- Yesterday night a problem in one cell in SA1: fixed today in the morning and is fine.

SPB:
- No major issues during the week.

FXE:
- Continuing with commissioning this week. 
- Helium supply was exchanged yesterday during the weekend. 
- FXE also says they had remote users and process/communication worked nicely.

MID:
- Would like to remind about the bunch train-IDs. MID need feedback to inform users who have experiment in two weeks.
	
HED:
- Stopped operation On Friday night due to M3 issues: photon beam can not be directed to HED.
- Problems with ADCs and controls last week: help was received.

SCS:
- Not present.
- Remote experiment also seems to have worked.

SQS:
- Remote shutter control seems that worked once but no reasons/correlations were observed.
- Experiment with remote users worked nicely.

General Announcement:
-  XO is looking forward to receive today the Delivery and Operator tables from the instruments.

CTRL:
- CTRL has carried out the time server deployment with newest version for devices and upper channels. 
- Nothing else severe to report.

DA:
- Working with HED on recording data - ongoing today.
- K. Wrona states that should be treated as experimental issue. An offline discussion will take place in defining how to interpret and run in the proper way.

EEE:
- The implementation of SA3 pre-absorber into the Interlock system was done, tested and it is working.
- 

VAC:
- Systems are running well.

XPD:
- Graphite filter in SA1: SPB has checked and found out the graphite filter is not damaged. The crack related to an attenuator. 
XPD will find an agreement/compromise for operation at higher energies when filter is retracted due to the wave-front distortions for the hard X-ray in SA1 and SA2. 
XPD needs more info from instruments. Discussion will follow.
- XGM resonances: a clarification is made that no matter which gas it is there is a resonance. Exchanging gases requires XPD to make an intervention for about 1 hour.
This has to be taken into account when, e.g. SCS and SQS require such changes.

DET:
- Nothing to report.

ITDM: 
- Nothing to report.

XRO:
- The Karabo GUI for SA3 is redesigned due to the presence of the pre-absorber. XRO will be happy in hearing comments and suggestions.

LAS:
- All Laser working accordingly to the specifications.

UNSYS:
- All is fine.

SPB:
- Operation going fine.
- Timing team found 2 issues: 1. Pulse pattern recording device seems not be synchronized with train IDs of other devices; 
2. Bunch arrival timing monitor has 25% repeated data (they have the same time stamp but different train IDs). 
K. Wrona says this may indicate there is no data. Robert Schaffer states the bunch arrival had no changes, so it seems to be another issue.

FXE:
- Starting user experiment and all going fine; pump probe signal seems good and FXE thanks LAS for fixing it yesterday; Digitizer issue was resolved by CTRL yesterday.
- Bunch arrival monitor is also repeated showing same numbers for the different trains.

MID:
- All fine.

HED:
- DAQ tests ongoing.
- The Shot on demand for laser stopped working at 3:00AM today (BBP signals). It seems to be a PPU problem. Nerea J. will contact T. Preston to look into it.
- Trying to get the A0 monitor working. After restart uTCA it solved one out of 2 problems. HED need someone to look into it onsite at the instrument.

SCS:
- Issue with pop-in imager last night: not allowing interlock. It has been under work now and is a similar issue as the SQS pop-in last week. This time it is the SCS-
XTD10 Pop-In IMG-PI (type I).
- Reducing SA3 bunches number were affecting SA1.

SQS:
- Nothing to report. All good so far.
