Hi everyone,

there was some miscommunication between us and DESY: only the Timing firmware and doocs server need to be updated, the RTM was already been replaced. This require update is similar to the one perform two weeks ago (see entry #449).

The time slot for this update is next Wednesday, 23rd January, between 16h and 17h. The update will affect all Timing Devices in SASE1. This operation should not take more than 10 minutes; during this time no timing signals will be generate (clocks/triggers/bunch patterns/etc.). Naturally, problems may occur during this update which will lead to increase down time.

If somebody sees a problem with the current schedule, please contact me.

General remarks:

• Stable beam only to be expected starting from 1.03. for SASE1 instruments commissioning
• There is no guarantee for parasitic beam delivery to the experiments. If it happens at all it  will most probably be during the last week of Feb. This has to be agreed on the fly  with the BKR and H.S/ T.T.

SPB/SFX:

• Preparing D.02 for mirrors installation (next week)
• Karabo being updated

Advanced Electronics:

• Trigger delivered by DESY should be back and stable at 10Hz. 
• ATM for timing has to be replaced in the balcony rooms. Bruno Fernandes is trying to find a way to reduce the downtime down to 30 minutes. Will be scheduled in the next days.

ITDM:

• 1 line card has to be replaced. Probably happens on Wednesday this week during the DAQ tests.
• Tuesday afternoon the online storage units will me remounted with the same path of the offline ones.
• This week a proposal for the in-house commissioning is going to be circulated.

SPB/SFX:

• 2nd AGIPD intervention will be finished today.
• SE worked on a reliable procedure for nozzle exchange and trained the instrument scientists
• SmarAct motors are in error, Mahadi / AE is informed. These motors are needed for user operation / commissioning.
• loop 5 update still outstanding
• Karabo update for loop 1-4 was done, seems to be ok. Full update is planned for beginning of next week.

FXE:

• JJ X-rays finalized installation of the last components at FXE:
  • Diamond grating (in XTD9)
  • Spectrum analyzers
  • Timing tool
  • repositioning of the sample manipulator and working on better cabling
  • minor work on cables of FXE CRL to allow full movement along the beam direction
  • Johann spectrometer
• FXE got the information from CAS that the Karabo update was successful and it’s ready for testing
• FXE decided not not pursue the further commissioning of the new equipment due to the emergency power off tests
• FXE is working on a more universal sample environment allowing faster and more reliable changes from solid to liquid experiments.

Vacuum:

SASE1:

• vacuum system closed,
• PLC loop update done,
• ready for restart

SASE2:

• XTD1 all devices in the tunnel and aligned

• SASE3 XGM:
  • test with Kr gas supply yesterday/today
  • test with gas plus HV
• SASE3 PES:
  • ordered grounding works (cabling) to be done similar to what was done for the XGM
• SASE2 XGM:
  • vacuum incident: vacuum operation of the XGM in XTD6 was unauthorized interrupted for some time, The rack had been powered down without prior information to XPD.
  • Reminder to all that rack near the XGMs shall be powered down only after informing and coordinating with XPD.

Laser:

• SASE1 PP-laser commissioning and upgrade is continuing according to our plan.
• Karabo upgrade to 2.2.1 was rather uneventful and successful.
• Hutch readiness milestones for laser hutches in SASE 3 and 2 seem to consolidate:  15. March. If this continues to hold, we will start our Phase II installation of PP-lasers in E.04 and A.04 with laser tables at the start of April. Laser tables for the ILHs will be installed at the same time.

Detectors: Did not attend.

Advanced Electronics:

• Replacement of the microTCA for the PES was done

Event trigger #16 is now back to 10Hz and it will still that way.

Dear all,

I communicated today on the 13h meeting that the Trigger #16 was back to 10Hz; this is no longer the case, the trigger signal is back to 1Hz.

Dear all, 

following up from the message #449, the MicroTCA Crate in rack 1.2 has been rebooted. Timing system hardware is now running firmware v1.24.0.

SPB:
- one mfpga board was found malfunctioning and was replaced with the old one. Concerning the mc the new version can be used.
- Liquind jet test ongoing.
- Waiting for the Loop 5 to be updated by AE
- Old version of Karabo was sluggish as of yesterday.
- 2.2.1 Karabo verion being rolled out for SPB - test ongoing.

FXE:

Vacuum:
- SASE1 vacuum in the tunnels closed (CRL chamber closed).
- KB mirror chamber in D.02 (SPB optics hutch) will be opened at the beginning of February
- In SASE3 the gas supply is now decoupled from the vacuum loop
- Soft XRay mono vacuum to be closed today.
XPD:

Detectors:
not represented

AE:

-XTD 2 CRL to be tested tomorrow
- Update of loops ongoing
- Emergency off button test in FXE showed that the relative controlling PLC was not configured correctly. In addition, communication problems between TS and FXE made things more difficult. PSPO will talk to TS and decide how to proceed. In the meanwhile the test foreseen in SPB for next monday HAS BEEN CANCELLED. GWellenreuther has informed Torsten Schoen.



ITDM:
 - Meeting this week to decide whether to use or not the train builder for 
AGIPD and LPD detectors
 - in 3 racks in XTD10 some network connection added last year do not work 
properly. The responsible company solved the problem without bringing down the loops.

CAS:
- 2.2.1 Karabo was deployed in FXE experiment and tests are ongoing.

- 2.2.1. being rolled out in SPB exp and Laser

- SASE3 tunnels  tunnels will get the new Karabo version next week. SASE1 tunnels will follow (probably in the same week) 

SPB:
- The exchange of the mc and mfpga boards has been done and some problems were found. The boards are now being debugged at CFEL.
- Sample enviroment's group is testing the liquid jet this week.
- Wait for the Loop 5 to be updated by AE

FXE:

AE:

- Timing devices update done. One crate in XTD2 has a problem and cannot be operated remotely. Fixing ongoing.
- The clock, VETO and Start signals for the AGIPD could not be brought correctly from the utca in the rackroom to the patch panel in the hutch due to the excessive cable length. Workaround found using a signal replicator at the patch panel position. The problem seems to be solved.


ITDM:
 - LPD recabled with Infiniband connection. Test succesful.
 - Meeting this week to decide whether to use or not the train builder for 
AGIPD and LPD detectors
 - in 3 racks in XTD10 some network connection added last year do not work 
properly. The responsible company is comeing back next week to check the 
cabling. Interventions have to be planned accordingly since the Beckhoff 
loops are running! ==> no news.

CAS:

Dear all,

with the exception of one board, all boards in SASE1, SASE3, FXE, SPB and PPL have been successfully updated. All Timing boards are now running firmware v1.24.0. The doocs-x2timer-server has also been updated in all CPUs; running version is 7.8.

The problem occur in the Timing System of rack 1.2 located at XTD2. The MCH board is not reachable via ssh/telnet/web interface; thus I am not able to power cycle the timing board, which would make the hardware load the latest version. The board is currently running (i.e. generating all the timing signals) but with an older hardware version. During the next week this problem will be tackle this problem with a quick visit to the rack.

Cheers.

Hi everyone,

after talking with the responsabile people, here's the timetable for the Timing firmware/server update:

In the meantime, all of SASE1 and SASE3 machines have been updated (with exception of the MicroTCA in the SASE1 Balcony room) with no problems.

Dear all,

an update of the Timing boards firmware and doocs server is require. This operation should not take more than 10 minutes per device; during this time no timing signals will be generate (clocks/triggers/bunch patterns/etc.). Naturally, problems may occur during this update which will lead to increase down time.

I will perform this necessary update in the devices locates in SASE1 and SASE3 tunnels today at 11H30. If somebody sees a problem please contact me.

Concerning the devices in the Experiment Rack Rooms, I will contact a responsible person to schedule a time slot where this update can be perform. If are one of these people contact me.

The MicroTCA crate used in rack 3.4 (XTD10) has been replaced. The system is up and running. Timing information is properly distributed from this system to the MicroTCA system in rack 3.2 and XGMXTD10.

Hello everyone,

The main Timing System at DESY, which distributes all timing information to our systems, is right now configured to generate 1Hz trigger signals on Event #16. This is the trigger that is deliver to most detectors/cameras on our site.

DESY is testing a new Gun and wanted to use a slower trigger frequency during this evaluation.

We were not inform in advance about this reconfiguration. After a few colleagues from SPB approach us reporting this problem, we contacted DESY and got the update. We will take steps to make sure that future Timing changes done by DESY are communicated to XFEL ahead of time.

Hi,

the FXE Mono's won't be available via Karabo from 15.30 onwards due to an update from CAS (karabo) and ITDM (server).

Best, Dennis

Dear Monica,

Just one small correction at "Karabo 2.2.0 being deploy today for FXE." The version is, actually, Karabo 2.2.1 that we released yesterday.

Dear all,

we got the information from MKK, that they have to fix a leak in the main compressed air line. Therefore they will close the valves to the tunnels for approximately one hour starting today at 1 p.m.

Please do not use the compresed air system in the tunnels during that time with air driven tools or air guns, as the volume of the distribution systems acts as a buffer.

Regards,

Martin

Dear all,

according to H. Sinn the closing of the XTDs 2, 4 and 10 will be delayed until the 30th of January.

Cheers, Gerd
