Data Acquisition and Data Archiving

• K. Wrona summarised the basic ingredients of the system.
• All components are ready and tested individually
• Integration in the instrument environment is needed and will be done first in the context of commissioning LPD in FXE starting from 5 July
• DAQ and archiving for the tunnels was originally not foreseen but is being worked on now
• The split up of the KARABO environment into several "Topics"  was done on purpose to allow development with minimal interference
• The separate topics have to be re-integrated now
• The sildes from Krzysztof can be found here

XTDs

• KMONO integration should happen next week starting on Monday
• The planned work on the network switches should only start on Tuesday as it interferes with KMONO integration

FXE

• Topics to be worked on next:
  • Vacuum interlock integration
  • LPD integration
  • uTCA digitizer (was already working in Karabo 1.4.7)
  • Great Eyes Detector has a rate limitation that was not there before
• Longer term topics
  • Gotthard detector

SPB

• Loops 12 and 5 are prepared and uploaded but need to be commissioned now
• Firware for loop 13 is needed next
• Many motors seem to be getting 24V, but should be ruuning with 48V. What is wrong? This needs to be checked in the EPLAN and CRDs
• Loops appear to be missing components

Detectors

• LPD goes to FXE on 5 July. Integration work in the hutch starts immediately after
• AGIPD then goes into the X-Ray test stand in HERA-S
• Note that the DAQ infrastructure can only support one detector at full rate at a time. 
• In principle this should not be an issue at 30 bunches but it requires the veto system to work which needs testing

Electronics

• Work this week concentrated on preparing everying for deploying the instrument vacuum interlocks next week
• The problem with wrong names in the PP laser was identified as a wiring issue in one crate 
• Work also concentrates on timing and train builder to support detector integration from next week

As discussed offline with NOC, Monday schedule was already fixed and not movable to Tuesday. Therefore, the network maintenance will take place on Monday 7:00 - 9:00.

During that time, no stable network is guaranteed.

After the network maintenance, the foreseen update and restart of all control server will take place, which take approx. ~2 hours. The exceptions are sase1 control servers and plc gateways as well as data logger and brokers and probably most importantly, exflgateway. These will be done after the work in sase1 (KMONO integration) is finished.  

General

• Accelerator was down all weekend due to cold compressors that were damaged in conjunction with the power outage on Friday
• Since 0700 all interlocks are broken and tunnels are open.
• Tunnels except XTD9 stay open until Thurday.
• XTD9 can remain open longer

Availability of Networks

• Network mainentenance that was requested last Friday for Tuesday has to happen today together with the rest of the facility. It was scheduled for 0700 - 0900 and is already almost done
• Following the network maintenance, N. Jardon will bring down the motion loop for KMONO integration. This only affects the tunnels and instruments can work during this time
• After the work by N. Jardon, IT needs to replace kernels on server machines. This will result in KARABO being down until early afternoon
• Afterwards CAS needs to bring back KARABO
• All measures will be announced on this log book

Instruments

• Implementation of vacuum interlock should be implemented this week. 
• SPB requires several adjacent loops to be included. Some of them are not up or complete. Maybe a simplified version should be installed first
• SPB requests loop 12 from AE. However this will take until mid July as it contains new motors (SMARAGD) that have not been tested so far

AE

• Work is currently ongoing on preparing to connect instrument interlocks to the DESY MPS system
• Work is also required to fix problems for the laser group that are most likely due to faulty wiring or a broken terminal

IT

• The dual power supply for switches saved a lot of work for IT after the power cut on Friday
• Unfortunately, the PLC CPUs in SASE1 are not on dual power. This should be upgraded as it is now also planned for SASE2/3.
• Dual power should also be put for the uTCA systems

Dear all,

We will be working in the Motion loop till this afternoon. So as I said in the morning meeting, I will let you know when we have finished.

Thank you

Dear all,

based on the information from todays BKR-meeting and communication with Harald Sinn, I updated the TAS: https://docs.xfel.eu/share/page/site/PSC/wiki-page?title=Tunnel_access_schedules

Basically, Harald is trying to keep XTD9 open until middle of next week, he still has to talk to DESY...

Cheers, Gerd

All control servers, brokers, dl and finally gateway were updated and restarted.

Here attached the main SASE1 panel

Dear all,

In order to finish the configuration of part of Hirex devices, we need to make an update of the Motion loop tomorrow morning at 10am. Please drive your devices to safe position before this hour.

Thank you

Dear all,

Sorry for the short notice, but we have to do an update of the Vacuum loop in order to get the neecssary interlock for the experiments done. I will contact know WP74 and Vacuum group so they can be awared about their equipments.

Thank you,

Vacuum Loop is running again.

Thank you!

I am working this morning on following projects:

SA1_KMONO_SYSTEM
SA1_XTD2_KMONO
SA1_XTD2_IMGSR
SA1_XTD2_FLT

Please don't save these projects !

Dear all,

We need to update EPS SASE1 loop in order to finish the interlock communication for the experiments. I will do the update around 14h.

Thank you!

General

• Interlock was set in the injector last Friday
• All shifts were cancelled for the weekend
• Startup today and interlocks set in XTD10
• It is still the aim to have photons by Wednesday (info from XFEL runn coor at 10:30)
• XTD9 remains open until Friday afternoon
• Tests of the emergency off buttons by TS (Thorsten Schön/TS) need to be performed in the instrument hutches. This is currently scheduled for Wednesday and should be done this week but requires careful coordination in order not to break equipment and disrupt commissioning

XTDs

• Progress on KMONO was unfortunately not reported as W. Freund was involved in tunnel search during the meeting. A. Koch shall ask W. Freund to put an update in the log book
• A lot of work was done on XTD10 installations last week, e. g. cooling water connections, gas attenuator installation
• Unfortunately, there is still a vacuum leak on top of the XSDU2 dump
• Work shall continue during the next break week in August and during individual service day if the opportunity is given

SPB

• Loops 5 & 12 are needed for the vacuum interlock. Hence cross-loop communication is needed. This requires additional testing
• Loop 5 is deployed but misses 2 modules that are being modified
• Loop 12 is not deployed and also requires that a few modules be modified
• The goal is to get the interlock up during this week

FXE

• The vacuum interlook will be deployed once the inter-loop communicationn has been tested in FXE
• JJ worked all of last week to 
  • Fix a leak in a bellow
  • Exchange one pump controller
  • Rewire motors to conform to XFEL standards
  • Install diamond screens in the imagers
• LPD was installed
• There is still confusion about the CRL alignment: Are individual lenses misaligned or the whole stack? This information is needed to obtain the next security level clearance from D3

AE

• AE will not attend the next meeting on Wednesday since there is a parallel event with MPS on the details of the interlock connections, in particular how to deal with the fast valves in the instrument hutches

CAS/ITDM

• ITDM is currently working with highest priority on DAQ for LPD. Once this is integrated, DAQ for the tunnels will follow
• Work on LPD DAQ is done in a separate KARABO "Topic" in order not to disrupt other work
• There are ocnfusing statements of whether DAQ can deal with more than one topic per SASE in the long run...

Important topics for this week

• Perform emergency off tests
• Get LPD DAQ going
• Integrate vacuum interlocks
• Make KMONO available for SASE tuning

Dear all,

We will do an update of the Motion Loop in the next 15minutes in order to fix one analog signal related to the KMONO.

Thank you

XTDs

• Mechanical operation of KMONO is prepared. Work is now ongoing on optimizing the scenes in KARABO
• Data from the SR imager that is needed for scanning the undulator gaps needs to be available in DOOCS. This is prepared.
• Once the machine can provide beam, one hour for KMONO first commissioning has already been agreed

SPB

• Test of the Emergency Power Off should take place this afternoon. PLCs will be shut down and hence parameters have to be put badk
• N. Jardon will put as much information as she can into the firmware do reduce the work of putting back the parameters
• However, in FXE it was found that the Emergency Off buttons only act on the interlock and not on the electrical systems. The situation in SPB is probably similar
• Work is ongoing on technical commissioning but there are still key components physically missing (e.g. CSS and Sample Environment)
• Vacuum interlock is not yet implemented as it is still waiting for a number of components  in loops 12 and 5

FXE

• JJ XRay worked last week and now the vacuum has to be re-established. Pump down should start soon but there was still one leak.
• Vacuum interlock definition is ready and it will be implemented by AE today
• LPD was installed. Currently 2 out of 4 super modules are installed. The other two should come early next week

DAQ

• Cabling and preparations are ongoing
• Tests should start early next week

AE

• Currently working on changes in loop 12 for SPB

CAS

• Currently working on bug fixes. Some of these bugs are probably responsible for the system not updating vacuum info for 30 minutes
• Deployment should happen this or next week
• There appears to be some confusion/communication issue as to what version of KARABO is installed where.
• It needs to be ensured that the startup of the next photon commissioning period goes smoothly

Dear all,

Tomorrow morning we will do an update in the Motion loop due to some hardware changes requested in Rack number 1.18. You might will not have communication with this rack during whole day, because they will be doing local test after changing the hardware..

Thank you and bests,

Motion loop is up and running again, as I have said, you will not have communicatin with equipments of Racks 1.18 till Denis finishes with hardware changes.

Thank you,

Dear all,

I updated and extended the tunnel access schedule (TAS) until the 24th of July. According to Harald, there will be an opportunity to access XTD next Wednesday. Please keep him informed should you require access.
