Dear all,

Tomorrow at first hour, some hardware modules would added in Rack 1.1 and 1.9 in XTD2 in the Vacuum loop. Therefore the communication would be interrupted till the firmware is downloaded to the PLC, around 10h-10.30h should be running again to add the XGM XTD2 into the loop. Although, I will post a new entry to let you know.

Thank you,

Tunnel Open.

Vacuum Loop:

Status:

• Communication problem with Ion pump controllers is fixed after adjusting controller settings
• Loop is now down to allow inclusion of XGM

EPS Loop:

Status:

• Temperature sensors return reasonable values after EPS loop fix
• EPS to MPS interface is working but fiber to central desy interface still lacking

Motion Loop:

Status:

• Should be up for testing PBLMs and Imagers

Imagers

Status:

• Test of FEL imager ok, but hampered by occasional slow response of the system
• SR Imager needs work on the driver

Tasks for tomorrow:

• Terminals need to be added and firmware adjustments made in motion loop (take loop down as early as possible for one hour)
• Test EPS inputs to MPS system with DESY people
• Power down crate 1.15 for grounding. Could take longer than one day

Other topics

• N. Jardon needs complete info of motor names in rack 1.18

Dear all,

The XGM XTD2 is already into the Vacuum loop and the loop is running. We would continue with the interlock tests today in the afternoon, but would not affect to other parts of the Vacuum loop.

Also was requested to change the Karaboo names of the devices in XGM XTD2, therefore a firmware updated would be necessary and would be performed today in the afternoon after VAC-MPS communication tests.

Thank you!

test finshed.

both stages were moved.

voltage value and position read out from encoder opposite in directionality

some strange limitation on the postiion range seen.

both stages are now at around the 0 position with few mm error.

XD to ask alio/nanoomotion on the matter

XD will provide few lines of comment

I expect that some of us may need the weekend as a reserve (e. g. mirror installation). So we should probably say no. Let's discuss more tomorrow at 09:30 

-

XTD2, FEL imager with Wajid

Screen, motor, switches - ok, minor braking switch issue.

LED, camera power – ok.

Filter, motor, parameter issue, should be solved now, to be tested again today.

EPS tests and SR imager tests, to be done.

XTD9 cameras, no power, will check today with Bernard.

 Tunnel Open.

Other topics

• Regular SASE1 readiness meeting at 09:00 tomorrow in XHQ E1.173
• Need to perform tests with EPS interlock conditions
• Need to test fast valve connection to VAC and to MPS
• Gas system for diagnostics needs to be flushed

Has anyone an idea why the motion loop is not working? Thanks Andreas

Hello Andreas,
please use redmine for bug reports. I opened a redmine issue for this:

https://in.xfel.eu/redmine/issues/16265

Please log in and give more details on what you experienced.

In case of emergency contact your main contact person Wajid.

Cheers

Alessandro

 Thanks, Alessandro,

I have made an update for the Motion loop requested to test correctly the Attenuators. Now the loop is running again.

Thank you and sorry for inconvenience.

Dear all, I will update EPS loop in order to integrate new hardware changes. I will post a new entry when the work is done.

Thank you!

Dear all, EPS loop is again up and running.

Thank you!

I have deployed the Karabo master (the HEAD of our development) in the control network for the Vacuum loop device server.

During last weeks Karabo was not able to cope with the data coming from the PLC for this loop (our biggest to date)
and would become unresponsive after 5 to 10 minutes.

The current system is online since 3.5 hours and is still responsive.

Please note:
This is a partial release and the GUI might show unwanted behaviour.
Please leave the vacuum loop untouched during the weekend.

In attachment you can find an example of unwanted behaviour and the DPS gui

Thank you very much and have a nice weekend!

Alessandro

Dear collogues,

we have added a hotfix to the framework, to make sure, that no motor can be moved if the feedback signals are missing. This update will be done due to the mentioned issue in the readiness meeting this morning.

We will update the loops again after the weekend, with a proper solution.

The hotfix will send all devices of a loop into error if the feedback of a terminal in the loop is missing.

I will write a new entire in the Logbook, if we are done with the updates.

Cheers,

    Tobias

Dear all,

I will update the Vacuum loop in order to add the XGM XTD9 into it. It will be running in few minutes again.

Thank you.

Dear all,

The Vacuum loop is running again, now with XGM XTD9 included. We will be testing interlocks in XGM XTD2, so could be needed another upload.

Thank you,

Tunnel Open.

Email by M. Schlösser re alignment

Hi Tobias, hi Markus, Hi Winni,

Tobias, we discussed briefly the schedule for the T9 and T10 beamlines for the next few days, when we met in the tunnel yesterday.

From what i understand it is impossible to finish T10 until April 11th from the alignment and vacuum side. And probably more important, this also holds true for T9. There is at least one major problem with the alignment of the mirror chambers of T9 in XTD2, which will need some additional days to solve.
From my understanding at least the T9 beamline should be closed and aligned before putting SASE1 in operation. While it will of course be possible to send electrons down to the XSDU2 dump, it will not be possible to send photons to the experimental hall with the current state of the beamline.

Since it is not possible to work in XTD10 while the SASE1 electron beamline is in operation, i would propose to also finish this beamline before SASE1 electron startup. Since there is major work to do in XTD10 to finish the beamline, there is no hope to  do the remaining work during maintenance days. Finishing the beamline would require a major shutdown of the SASE1 branch later.

Since there will be no alternative to send the beam to (e.g. SASE2) for the next year (?), it does not make sense to stop work in XTD10 now, just to continue later then, without any overall benefit for the machine.

Of course i don't have a complete overview of all the machine schedule, but from my point of view it would make more sense to finish work in the northern branch, at least to align all components and to close the vacuum system, even if that means some more weeks before the SASE1 startup.
