Dear all,

I have received a request from Konstantin Sukharnikov to break the Motion loop in XTD2 from Rack 1.5 in order to do checks in the CRLs. So you will loose communication with almost the whole Motion loop in SASE1. I will let you know when they are finished.

Thank you,

We are finished. One encoder terminal has failed and needs replacing: rack 1.5 EC14

It will be replaced today around 1pm.Therefore Motion loop will be broken from this rack position.

The encoder terminal in rack 1.5 has been replaced.

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,

access to XTD9 has been extended until the Friday the 14.7. 14:00. Tunnel access schedule has been updated:

TAS

Cheers, Gerd

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

During the first K-Mono test with Karabo on Friday the first goniometer THETA1 (Elmo controller) moved beyond the CW limit switch and stopped  at the CCW switch. So the goniometer was trapped between both switches with a movement range of a few degrees. Movement of encoder and motor were opposite. This behaviour is not understood and under investigation.

Now the goniometer is back within the nominal range and movement of motor and encoder reading is consistent. CCW limit switch at 117.5° / CW limit switch at ~182°.

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,

One power supply needs to be changed in SASE1 XTD9 rack 1.12 tomorrow and it's related to the Vacuum loop. Denis Finze will do this change tomorrow morning, but we have to make sure before that we have all the equipments after this rack 1.12 in safe state (most concerning part, XGM in XTD9). Please, could you make sure that everything it's ok tomorrow at 10am? However I will send an email now to the involved people.

Thank you and best regards,

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.
