General

• Technicians from Actemium/JOWO arrived and found that a lot more connectors than originally estimated need to be replaced
• Tests are finished in SPB Optics (40 connectors to be replaced) and continue now in FXE 
• Replacing connectors starts tomorrow with 3 technicians and should take 45 minutes per connector 
• There is an interference of connector replacement and tests of the interlock. This needs to be resolved.
• Starting this week, new messages in the elog appear not to be sent to all registered users. (Info from J. Szuba: Some users intentionally or unintentionally un-subscribed)
• WLAN access at the end of XTD9 is not very good and not sufficient for testing cameras, e. g. in PBLMs

XTDs

• On the weekend the broker queue filled up. This was fixed using "extreme measures". This led to V0 closing and  BKR crew was not aware of the state of V0. It is the opinion of the experts that the BKR crew could have known but were not fully informed where to look
• The motion loop was updated yesterday for PBLM tests. But the update was not complete and will be redone today before 12:00
• PBLM tests with Mahadi and Natalia shall start after motion loop update
• XTD9 will be closed on Thursday (not confirmed)
• There has been a modification of the interlock conditions by RAUL for the gas section. This needs to be carefully checked.

FXE

• Communication is now possible with the ion pump controllers but there is still an error message from the controller that cannot be interpreted. The manufacturer of the ion pumps (AGILENT) has been contacted
• JJ XRay is here this week. They work on the patch boxes for the CRLs and the von Hamos Spectrometer
• The LPD 2-tile system will be brought into the hutch today to test the controls
• Commissioning on motors continues

SPB

• Currently there is no working version of Karabo for SPB (Fixes were implemented that broke base functionality)
• Loops 7 & 12 have not connectors affected by water and could be commissioned. AE was informed to provide firmware

Laser

• The humidity in the hutch is down to 50%, but still oscillates
• AE is fixing connectors with water problems
• After PLC cycling the Beckhoff terminals loose the proper parameter set. This issue needs attention.

Software

• Deployment of next KARABO version is postponed until the new version switching method is sufficiently tests. H. Sinn points out that this version (2.1.12) contains many urgent fixes and is needed asap.
• The incident on the weekend showed again the need for the consolidated list of mandatory devices. This is being worked on 
• The bug where the gui server looses track of the state of the system is still not fixed! If it occurs inform CAS immediately

Dear all,

Due to some hardware changes needed in Motion loop, we will last a little bit more in the Motion update. You will loose communication but I will come back when it is running again.

Thank you and sorry for inconvenience.

Dear all,

Motion loop is up and running again, now with all the PBLMs configured.

Thank you,

Dear all, 

according to the DESY logbook XTD10 will be opened today again: See DESY logbook entry:

'due to the cryogenic failure we will open XTD10 from 9am for working.
at XTL and XTD2/4 ZZ is possible for repairs/work.'

I don't know hoe severe the cryo failure is, but otherwise the agreement is that XTD9 will be closed Friday morning around 9am.

(I assume that they may close Friday morning also XTD10 again).

Best regards

Harald  

General

• E. Boyd presents a summary of the next tasks for the radiation measurements for hutch commissioning. There are some dates (13th and 20th June) that safety needs exclusively access to the hutches. Safety will be in close contact with Instruments to agree the dates.
• Tests are finished in SPB Optics (40 connectors to be replaced) and continue now in FXE.
• There is an interference of connector replacement and tests of the interlock. If Instruments grant exclusively access for the Interlock works, this has to communicate to PSPO to inform company JOWO that is working in the cable reparations.
  
• Starting this week, new messages in the elog appear not to be sent to all registered user. The system unsuscribed automatically from one elog when you suscribe to a new one. IT has already fixed this problem.
  
• WLAN access at the end of XTD9 is not very good and not sufficient for testing cameras, e. g. in PBLMs

XTDs

• Motion loop updated twice during this week, but there is still an issue with Elmo limits. AE will first test a solution and decide if a new update is necessary.
  
• PBLM tests with Mahadi and Natalia shall start after motion loop update.
  
• There has been a modification of the interlock conditions by RAUL for the gas section. This needs to be carefully checked.
• There is a request to improve the information when the tunnels are open/close, now it takes too much time to find the information in the elog. Suggested to have a unique place with the information up-to-date.

FXE

• There is a mistake in the channel assignment of the Ion pump controllers, modules BKF00074 and BKF00096 will be modified today. Moreover firmware for loops 1 and 2 have to be updated.
• JJ XRay is here this week, acceptance test for CRL is done. Work will continue with von Hamos Spectrometer
• The LPD 2-tile system brought into the hutch to test the controls.
• Loop 8 already deployed.
  
• Interlock defintion for FXE is done.

SPB

• Currently there is no working version of Karabo for SPB (Fixes were implemented that broke base functionality)
• EET is working to generate the exports for loops 7 and 12.
• There are still some mismatches in the connectors of 11 cables, A. Legrand working with Actemium to fix the problems.
  
• In loop2 one module is being reworked by AE.
• SPB is also affected by the problem with the Ion pumps, AE to figure out which modules have to be reworked.

Laser

• The humidity in the hutch is down to 50%, but still oscillates
• AE is fixing connectors with water problems
• After PLC cycling the Beckhoff terminals loose the proper parameter set. AE working on that issue but need soe additional information.
  
• There is a mismatch beween the motors and trthe control, AE will check if it a firmware or hardware problem.

Detector

• LPD test working succesfully, waiting when FXE hutch will be ready to move the LPD. Radiation protection has to be finished before to move the detector.

Software

• Deployment of KARABO version 2.1.12 will be deployed today to FXE. D. Goeries shows a presentation with a description of improvements in the new version.

Tunnel's schedule:

• Monday 12th June:  XTD10 closed, XTD9 open
  
• Tuesday 13th June: from 7:00 to 15:00 all open.
• There is a request to have a unique place with updated information when the tunnels are open/closed, PSPO is working to set a place in the intranet and will inform as soon as this will be agreed.
  

General

• Cable reparations on OPT hutch on going, FXE will follow.
• WLAN access at the end of XTD9 is not very good and not sufficient for testing cameras, e. g. in PBLMs. ITDM re-cabled some ports and provided office network port in rack 1.17 that could be used to commission the cameras. According to Liuba it worked well.
• From 08/06/2017 the ITDM group provides the OCD service. The general principle is that the 1st level support is provided by CAS group and in case they cannot solve the ITDM related issue they call us. The phone number for ITDM OCD is: 98070 or directly +49 175 9814494. There is a single number for 3 mobile phones so the number is valid independent on the person providing OCD.

XTDs

• Motion loop updated twice during last week, but there is still a feature to be fixed.
• There has been a modification of the interlock conditions by RAUL for the gas section. Already implemented and working.

Software:

• Karabo version installed in a different domain, CAS is still testing ths version to ensure a smooth transition from one version to other.

XTDs:

• DESY requests the KMONO to be commissioned since the K Values of the undulators appear not to be as accurately calibrated as originally advertised. Management decided to put KMONO at the top of the priority list for this reason. W. Freund should work together with Mahadi and Nerea on getting the two goniometer motors (ELMO controller) working. When software is ready a ZZ access should be requested
• Latency of FEL imager is ~ 5s which is a problem for tuning and scans. M. Messerschmitt is looking into this. A. Silenzi was not aware of the problem up to now.

Dear all,

I extended the tunnel access schedule up to the beginning of the shutdown (3.7.). As always, you can find it under https://docs.xfel.eu/share/page/site/PSC/wiki-page?title=Tunnel_access_schedules

Access request to Harald Sinn. Works during the shutdown have to be reported to Harald Sinn and Dirk Nölle for scheduling.

Cheers, Gerd

General:

• ​Beam was brought to all SASE1 hutches on Friday. Beam was available to both instruments splitting it with M3 until Sunday morning. Afterwards SASE tuning was done and the beam should be back in the hutches some time today. Beam operation will continue this week with very low intensity. Split beam operation to both instruments.
• Rules as follows:
  • Only one bunch and very low intensity (< 100uJ)
  • Mechanical manipulation on vacuum parts only when shutter and all-metal gate valve are closed
  • Shutter and gate valve closed when instrument people are not in attendance
• CAS appears to be in a 2 day workshop from 9 - 5. This is a problem as some urgent work is needed. 

XTDs

• No access for KMONO commissioning this week
• All preparations that can be done for KMONO operation should be done however
• M. Messerschmitt prepares interface for the FEL imager to DOOCS so that KMONO can be used for tuning

SPB

• A list with essential components has been prepared
• It appears that some of the previously brought up loops contain only vacuum components. This should be fixed
• Loops 5 and 12 are needed most urgently now. 
• 5 additional servers are needed from CAS

FXE

• No remarks from FXE

Dear all,

I tried to update the TAS to include the times for each XTD during the shutdown-week at the beginning of July. It is currently not entirely clear when XTD9 and XTD10 will be searched, and as always this is subject to change...
