The karabo services will be down for an upgrade for an hour.

The access will resume at 13:30.

Dear all,

Right now both XGMs are into the loop and would be running. The loop must run continuously, in case you should do any work, just let me know in advanced.

Thank you,

Dear cllougues,

we will run an update of the EPS-loop, in order to have a proper solution for the latest hotfix, as it was announced this morning in the standup meeting.

Cheers,

    Tobias

Dear all,

EPS and Motion loop have been updated to the last framework version with the last hotfixed. Vacuum loop would be done tomorrow in order to let the XGM work the hole night and part of the morning tomorrow.

Best Regards,

Dear all,

Vacuum loop is up and running, we would wait till Raul check the interlock of the "OK" signal for the Vacuum and then, if everything is correct, we would put again the XGM controlled by the Vacuum PLC.

Thank you!

Tunnel Open.

Mirrors:

Status:

• Vacuum on M2 should be good enough to switch on ion pumps
• Surveying work going on 

Vacuum Loop:

Status:

• Several vacuum sections successfully tested in XTD9 yesterday

Dear all,

Motion loop is running again with the last update (names for PSLIT and LVDT have been changed).

Thank you,

Dear all,

Sorry for disturbing again, I will do a small update to put one missing coupler in the hardware configuration in rack 1.18, the loop would be running again in few minutes.

Thank you!

Please find in attachment the dowload bash script for the latest Karabo.

if your system has a "karabo" directory, this script will not overwrite it, but the update will fail.
In this case, remove or rename the karabo directory.

To use it:
1. download the script in a directory of your choice.

2. open a terminal and execute it with
   $ bash PATH_TO/download.sh

Where PATH_TO is the path where the download script was saved.

Dear all,

The EPS loop would be stopped, in order to correct some issues with the hardware in Rack 1.1 and Rack 1.5 in XTD2. We will upload it as soon as possible and I will post a new entry here when it is running again.

Thank you,

Both SASE1 XGMs (in XTD2 and XTD9) are now again in the Vacuum Control Loop, their vacuum being controlled by Beckhoff/karabo. This works fine.

Therefore: DO NOT FOOL AROUND WITH THE VACUUM LOOP !

Since we all cannot enter the tunnel XTD2 in the next two days, it's agreed that the Vacuum Loop is NOT going to be touched at all, since  we cannot intervene in the tunnel if something goes wrong.

Imager Status, 12.4.17

-          All imagers tested, motors and cameras, motion loop, EPS loop, for 3 imagers XTD2, and 3 imagers XTD9.

-          All blocking issues concerning tunnel closure solved.

-          Remaining issues:

Mirrors:

Status:

• No information on status of mirrors and PBLM since Optics group was not at the meeting

Vacuum Loop:

Status:

• All vacuum sections were successfully tested in XTD2 yesterday (work ended very late)
• DPS was tested successfully and all interlocks and remote controls were working
• The protection switch on the ion pumps can still not be actuated remotely 
• XGMs in XTD2 and XTD9 fully in the interlock 
• V0 valve and absorber were moved and interlock tested. Communication with DESY was also tested and is ok.

EPS Loop:

Status:

• No explicit information today (see remark above)

Motion Loop:

Status:

• No explicit information today (see remark above)

Imagers

Status:

• All imagers in XTD2 are ok
• Trigger is not working on one of three imagers. 
• Testing proceeded in XTD9 yesterday
• One camera in one pop-in can not be reached (Network problem?)

Karabo:

Status:

• Running stably
• Work required now:
• Photonics Camera driver
• Clean up the project database
• Clean up master equipment list

Tasks for today:

Note: All loops should be left running and no changes to Karabo.

• Proceed with remote testing
• Check out adequacy of scenes
• Monitor stability and responsiveness of GUI Server and Log Servers 
• Set up monitoring of temperatures and pressures overnight (A. Silenzi)
• Cleanup Karabo

Tasks for tomorrow:

Other topics

• Tunnels open over the Easter weekend and also during the day on Tuesday 18 April
• There will be a SASE Readiness Meeting at 09:00 on Thursday in XHQ E1.173

 Tunnel Closed until approx 1300, Open over the Easter Weekend until Tuesday 1500.

Vacuum:

• All valves and pumps in XTD2 are working and can be operated remotely
• The vacuum system including DPS and XGM is interlocked. Interlocks have been tested and are working properly
• The fast valve and the absorber at the interface to the electron beam vacuum are working and interlocked. The communication with DESY has been successfully tested
• Some issue exist when switching turbo pumps on/off in Karabo. Then erratic behaviour is observed. Doing the same remotely communicating via TCP directly works ok
• More testing needs to be done in XTD9

Mirrors, PBLMs, SRA, Attenuator

• M1 and M2 are installed and under vacuum. M3 will be installed after easter
• 3 out of 5 motors can be operated in M1 and M2. The mirrors have been moved into a safe position
• PBLM motors (ELMO driver) can be operated (started and stopped) but operation is still problematic (motors stop in wrong position, movement not linear)
• On the SRA the connection to two motors is interchanged
• On the attenuator certain motors occasionally get stuck
• Slits have been moved out so the beam line is safe for first operation

Imagers:

•  
• All imagers tested, motors and cameras, motion loop, EPS loop, for 3 imagers XTD2, and 3 imagers XTD9.
• All blocking issues concerning tunnel closure solved.
• Some remaining points that can be treated remotely: Trigger, software delays, others.
• The Photonics Camera driver is now working in Karabo.
• Cameras can currently be read out at 3 Hz which is too slow but ok for first beam commissioning

XGM:

•  
• XGM inserted into vacuum loop and interlock (in XTD2 and XTD9)
•  
• Grounding completed in XTD2+XTD9 (power cycle of rack was needed)
• Gases ready to be used in XTD2
• XGM @ XTD2 ready for beam         (need DOOCS middle-layer servers activated) 

FXE

• Testing finished for all devices in loop1
• Now waiting for loops 2 and beyond
•  

SPB

• SPB tunnel loop deployed. Testing can start next week
• For the Optics hutch some Beckhoff crates are still missing 
•  

PLC

• Fixes to MC2 library (ELMO and TECHNOSOFT motors) will deployed next week and then tested in XTD9
• FXE loop 2 was modified and loops 3&4 are deployed
• SPB loop 1 to be deployed today. Working on loop 2

KARABO

• Slow response appears to be solved
• There are other not so severe bugs on the backlog
• Currently all high priority components are supported
• No requires cleanup and day-one component list
• Monitor stability and robustness

Tasks for today:

Note: All loops should be left running and no changes to Karabo.

• Fix the issue with the disconnected vacuum loop after tunnel reopens

Tasks for the weekend:

• Relax and look for Easter Eggs
• AE and CAS will provide contacts on a good will/best effort basis in case an intervention should be necessary

Radiation Interlock Tests are finished. Tunnels XTD9 and XTD10 up to the fence at the dump can be accessed right now. Magnet current interlock tests still takes a bit of time (ca. 1h). Once this is also done, I shall post a note 

All northern tunnels XTD2/4/9/10 are fully accessible again! 

Dear all,

The Motion loop would be updated now in order to fix names problems with PSLITs motors. In few minutes would be reachable again.

Than you!

Dear all,

The EPS loop is running again with the last modifications concerning devices' names.

Thank you.

XTD Tunnels open until 15:00. Later XTD2 and XTD4 are closed, XTD9/10 remain open

Vacuum Loop:

Status:

• One broken Beckhoff terminal was exchanged before the weekend. This was the first failure of this type in 2 years
• After this the system ran without hickup over the Easter weekend
• The fix applied for ion pumps that avoids triggering an interlock condition when there is a communication failure on the serial output should be also applied now to other vacuum device, e. g. the turbo pumps

EPS Loop:

Status:

• Requires an update to be done asap so that N. Gerassimova can continue tests with the PBLMs afterwards

Motion Loop:

Status:

• Movement of the PBLM motors (ELMO controller) is not satisfactory yet. Motors start and stop but the movement is uneven and stops not always requested
• There is no test set up in the lab. So tests have to be done in the tunnels (XTD9)

PBLMs:

• All systems in XTD2 were tested and cameras calibrated including some at the beginning of XTD9
• Work continues on remaining systems in XTD9
• System with motor movement is still unsatisfactory (see above)

Imagers

Status:

• 2 Imagers in XTD2 have no trigger signal. Suspicion is that this might be configuration problem. P. Gessler will investigate
• One pop-in (245) in XTD9 cannot be reached with IP. Suspicion is incorrect network configuration -> K. Fillipakopoulos

SPB Tunnel components

• Signal pins of the Attenuator crate were tested. DC voltage is seen there at different levels on different pins. This looks problematic -> P. Gessler

Karabo:

Status:

• Ran stably over the weekend 

Tasks for today:

Note: All loops should be left running and no changes to Karabo.

• Take equipment and junk out of tunnels
• Check trigger cabling for imagers in XTD2
• Check PBLM motor movement and continue testing in XTD9

Other topics

• Controlled access to tunnels is possible after 1500. Coordination with T. Haas and the DESY run coordination
