Dear All,

During the afternoon CAS has a group activity. Any support can be requested via my phone number: 9-6776.

See you,

Sandor 

The current slow response times in the karabo GUI are the following (some measured times for reference):

- opening a project from the project manager : 45sec (just loading, not yet touching any device or scene)
- opening a scene and receiving the status for all devices e.g. XGM@XTD2 : between 90 and 120 sec
- beyond that, it's never clear if the displayed gauge values are true/actual and must be separately read.
- reading explicitly a gauge value (with command READ in configurator) gives currently an updated value after about 10 sec (should be almost immediate when requested)
-----> working with this (getting actual work done) is practically almost impossible

- this is using the "new" gui server "sa1-br-sys-con-gui2"
- this is after 19h30 (shouldn't less traffic help the performance ?)

The vacuum loop is up and running again, with the version 1.11.4.

Denis Finze will connect the shutter signals of the XS3 shutter to the vacuum loop in rack 1.7.

WP74   OCD  for the  weekend 6.5.-7.5.2017:

Saturday: Jan, jan.gruenert@xfel.eu, 9-5777

Sunday: Theo, theophilos.maltezopoulos@xfel.eu, 9-6792

 Vacuum (M. Dommach):

• Systematic tests of ion pumps in XTD9 almost finished - ongoing
• Interface with MPS has to be tested
• Problem with the fast valve in XTD2 and 9 - it is possible to close it remotely but not possible to open it again. Checking of the cabling is ongoing by Vacuum group
• After restart of the vacuum loop many pumps in XTD 9 and 2 show an unknown error and some of them are not readble - CAS working on that.

PLC (P. Gessler, T. Freyermuth):

• Implementation of shutters in Karabo ongoing -XS3 shutter in the VAC loop now. XTD9 to do.

Karabo (A. Silenzi):

• GUI stability improved with a temporary solution. This should be enough to guarantee the proper functioning of images acquisition.
• Update of devices list ongoing
• Library for motors (base device), elmo and technosoft, being worked out.

Plans for today:

• XGM work on gas injection
• Bring back Karabo and clear XGM error codes
• Perform systematic test of DPS in XTD9

Other topics:

• No 09:30 meeting tomorrow - next meeting will be on Wednesday

Dear all,

I will make an update on the EPS loop, it will take only a moment.

Thank you

EPS loop in SASE1 is running again

Dear all,

The update of the Vacuum loop will take place in the next few minutes, later on, you would have access again to it.

Thank you.

Sorry for disturbing you, but I will have to wait till WP74 group finish a training in order to be able to put the XGM up again .

Vacuum is up and running again.

Thank you

CAS on call service for the night:

Gero Flucke: 9-8053

I will ramp down the system and bring it back up during the lunch break after installing the
tag 2.1.10.

To install a new version of Karabo use the script attached on your terminal

move your the karabo directory to a backup or remove it.

to backup:
$ mv ~/karabo ~/karabo.bkp
 

to remove:
$ rm -fr ~/karabo

then execute:
$ bash PATHTO/download.sh

 The system is up.

The users using virtual machines will encounter problems installing karabo 2.1.10 in the way that was described.
Further instructions will come later in the day

Dear all,

I will update the Motion loop to include the mc2 motors, it will be running again in few minutes.

Thank you!

Plan of WP74 OCD contacts for May.
Assignments are subject to change.

Initially availability is 10h-18h on the given days.
This might be adapted as well for later weeks.

 We are in the BRK and corrected the vacuum interlock condition.

We will restart the SA1 vacuum loop in a few minutes

Find attached the Instrument Component priority list discussed this morning.

Regards,

Monica

 for Users with a VM:
- use the download script
- Remove the karabo directory:
   $ rm -fr ~/karabo 
- then execute:
   $ bash PATHTO/download.sh

Sorry for the delayed instructions

Focus of meeting is on SASE1 Instruments, Laser and Detectors

SPB (B. Weinhausen)

• All motors in the SPB tunnel loop have been commissioned except for one TECHNOSOFT motor where the updated driver was not yet available
• Comment by P. Gessler:
  • The updated MC2 lib was deployed yesterday evening. Testing should be possible now
• The second camera of the screen broke. Concern exists over possible overvoltage in the power that comes directly from the PLC
• All encoders are working
• The vacuum in the Optics hutch is closed
• Info by A. Violante:
  • All cabling in D02/D03 is done
  • There are a few damaged connectors that prevent pushing in the modules. This should be fixed on Monday
  • Pins are swapped in one connector. Will be fixed locally
• Comment by P. Gessler:
  • This week AE was busy with AGIPD and tunnels
  • Next week resources should be available to support start of commissioning loop 1 

FXE (A. Galler)

• E2E tests are progressing 
• A recent update of the Beckhoff firmware generated new problems with encoders
• Info from T. Korsch:
  • The vacuum in the hutch is closed and has reached 5e-7 mb
  • There is a minor leak in one of the bellows
  • Compressed air is working to operate the gate valves
  • Vacuum gauges can be read out remotely
• Attention should be paid to being able to read out detectors, e. g. diodes

Laser (D. Kane/M. Lederer)

• Slides were provided in INDICO with a detailed account of the status. Only Key points are summarised here:
  
  • Hutch infrastructure is working in general and temperature stability is ok but laser group is lacking access to controlling the parameters, humidity is oscillating and smoke detectors are not connected
  • Pre-assembly of PP laser is 75% done
  • Beam delivery to instruments is on the list now
  • Synchronisation with optical system might not be available before October
  • Control are generally working and software has improved a lot but some stages cannot be controlled and Karabo appears still to have some resource leaks

Detectors (M. Kuster)

• LPD is in E2E tests and AGIPD is still being integrated into the XFEL environment
• This week it was possible to run the DAQ chain on LPD for the first time
• All tests on LPD including data taking in the X-Ray chamber in HERA-S should be done by end June
• Situation with AGIPD is more difficult as basic integration is still not complete

Discussion

• Follow up on progress with instruments, laser and detectors will continue in S1R meeting from now on
• The S1R dispatch meeting takes place on Mondays 09:00 in BKR and on Wednesday 09:30 in XHQ 
• Groups that require help from AE and CAS and that need to coordinate with other activities should attend
