Frederik Wolff-Fabris | General | Information | Notes XO Integration Meeting 15.03.2023 |
General Announcement:
- Tobias Clever informs on electrical works needed to connect XHO to electrical grid:
1. A new transformer will be connected to the new building on 03.April (a small chance of error can produce a minor power glitch as the ones frequently seen by Desy power glitches - usually this events
have not affected us in the past 2 years.
2. Second work on 11.04: test of auxiliary conditions that were installed in December; it will be connected for the first time and a chance that a power glitch could happen affecting more XFEL premises
(only affecting general power supply - all devices connected to secure or redundant power supply will not be affected).
There is only a small risk and is necessary to run XHO with power.
This is scheduled in a blue week and last similar event was in 2021 when cryo went down and XFEL systems were not severally affected, so it shall be contained event. An e-mail will be sent to xo-info list.
P. Gessler raises the concern that this is a blue week.
- Tobias Clever says that for chillers ordered by instruments please make sure a standing maintenance contract has to be done as degradation of coolants happen with time without maintenance. Maintenance
contracts are usually renewed automatically after the purchase contract is done. XO will forward the comment to DOB (to discuss level of maintenance contracts: individual or facility wide).

FXE:
- FXE can use the beam tonight if there is the wish.
MID:
- D3 shutter: BS6.2.3 shutter; root cause unclear if replacement of PC and/or IP address. Michael Dressel showed how to open shutter “manually” using the interlock box until it is finally repaired.
Root cause shall be identified still.

XRO:
- On SA3 M2: issue related to PLC update in December; apparently resulted with loss of calibration in one motor. All alignment were done with other parameters based on beam reflection.
- Steffen Hauf comments there was two different issues with different motors: 1. the calibration was solved end of last week; 2. from Saturday it was a problem with encoder which will be fixed this week
with EEE.
LAS:
- Stages with problem but running.
- SA1 will be ready for users by the end of today.
UNSYS:
- Small issue with SA1/cell22 air coils were fixed by Suren K.
SPB:
- Thanks to supporting groups for the bring-up days.
FXE:
- Nothing to report.
MID:
- Question on the availability of PP-laser in SA2: Daniel K. informs that is expected by the end of today but this will be confirmed with other LAS colleagues.
- Question about intensity in SA2: A. Galler informs there is no news on the cause of low intensity; Raul V. as PRC mentions currently it was reached about 500uJ at 9keV.
HED:
- Nothing to report.
SCS:
- Bring-up days today and SEPS interlock tests.
SQS:

General Announcement:
- As PRC, Raul V. thanks to CTRL and EEE for the work with the SEPS yesterday.
CTRL:
- New version for bunch alignment monitor devices (for pulse resolved operation). An e-mail will be sent to xo-info list.
- Regarding the issue reported by LAS: Karabo Beckhoff device went in error and a work around solution has been developed and to be implemented to reset the system.
- Issues with SEPS interlocks: PLCs devices went down at HED during tests.
Steffen H. says an interface issue with Karabo happened; interlock settings are protected; yesterday CTRL had to implement a new update and as consequence many PLCs went down.
DA:
- Bring up days going smoothly; few issues found were fixed.
EEE:
- Nerea J. informs that fix for the MDL for IMGS is deployed and shall work.
- SEPS modifications were done by lunch time yesterday. SA1 and SA2 were tested by end of the day. The SA3 SEPS tests will be done on Monday.
VAC:
- Nothing to report.
XPD:
- Hard X-ray PES was recommissioned last week. New Metrocal acquisition did not work; DA will investigate and inform XPD.
DET:
- Bring up days are ongoing.
ITDM:
- E-mail was sent for the dCache maintenance scheduled for next Monday.
XRO:
- Not present.
LAS:
- Issues with stages are under work and to be implemented today.
UNSYS:
- A ZZ in SA2 to replace PS motor in cell 17 took place. The motor was replaced and a few spares are still remaining.
- This or next week Pb shields will be received and ZZ would be required for their installation.
- Tomorrow the alignment of 4mm aperture in SA2 will take place.
SPB:
- Not present.
FXE:
- Nothing to report.
MID:
- Comment to XRO: alignment in tunnel XTD1 in ongoing.
HED:
- Broken pile-up on Monday happened. Steffen H. says that macros can be restarted now.
- Alignment in tunnels by XRO: HED needs some information on activities.
SCS:
- Busy with bring up days at hutch.
SQS:
- Not present. |

General Announcement:
- As PRC Jan G. says machine was tuned at 7keV for SA1 and SA2 and 700eV for SA3 with good performance. SASE tuning proceeded as planned with few issues blocking EPS.
- Analyzed the effects of the 4mmm aperture at the end of the undulators in SA2: it is not exactly in the center where the FEL is lasing.
It was found the FEL is well aligned at the IMG cross but is partially blocked by the pipe and is under discussion with RCs the next steps.
- Jan G. mention that one screen at SPB was in unclear state; also a software device was blocking beam in XTD9. A ticket was issued; initially the software blocking could not be identified.
Solution was to close the XTD9 shutter. Steffen H. suggested to also contacting the DRC for urgent and the technical problem with clone device will be followed up.
CTRL:
- Nothing to report.
DA:
- Nothing to report.
EEE:
- Busy with bring up days. No major obstacles were found so far.
VAC:
- Nothing to report.
XPD:
- Restart Diagnostics and photon systems last weekend went relatively fine.
DET:
- Finished with MID for ramp-up and today HED is scheduled. So far so good.
ITDM:
- Nothing to report.
XRO:
- On the weekend issues with MDLs run by the experiments appeared. A follow-up will be made to avoid problems in the future.
LAS:
- EEE was informed of issues in the balance cross correlators. Nerea J. comment that tests were done but not reproducible. More follow-up to be done today.
UNSYS:
- SA3 cell 18 issue with PS solved remotely last week. All fine with undulator systems.
SPB:
- Nothing to report.
FXE:
- Nothing to report.
MID:
- Bring up days were mainly a success; thanks to involved groups. All good.
HED:
- Bring up days were also successful. Thanks to EEE and CTRL.

CTRL:
- The requirement to add the associated karabo device name to the Master Equipment List before requesting the network registration of the device is not needed anymore.
Please suggest the karabo name directly in the network registration form.
In case of doubts please contact Wajid E.; J. Szuba adds the network registration form in XIM is changed (Karabo name is now optional). It shall be used when an ALIAS is needed.
