SPB

• KB chamber being pumped down
  

• interaction with AE is ognoing concerning update pf Loop 5 and AGIPD cooling procedure ongoing
• Smaract commissioning ongoing
• The goal is to be ready to start commissioning with beam on 01.03.
• Slit Karabo middle layer - integtration and final fixing being finalized by A. SIlenzi

 FXE

• DAQ test ongoing - fixing of bugs
• After FXE has been moved into the new topic is not possible to read tunnel vacuum pressure anymore. Being discussed with CAS
• Permission to use parasitic beam next week requested to the radiation safety group.

​XPD

• XGM in SASE3 requires physical intervention to be fixed. Access request for tomorrow.
• DAQ groups definition ongoing and being clarified with ITDM

AE

• PBLM moto problem was found to be due to a wrong Karabo-PLC linking. If the tunnel will be accessible tomorrow the issue will be solved. HSinn to decide on priority.
• Soft mono commissioning started and AE support was required. It is not clear what priority does it have. Mahadi is anyway working on that today ad 14:00. If the intervention is found to require more time one has to see.

ITDM

•  During the FXE DAQ tests many problems were found:
  • issues with digitizers
  • issues with scan
  • issues with images acquisition. In this case the problem has been identified (Train ID was 0). KWrona is in contact with CAS to fix the bug.

CAS

• The issue reported by SPB about no data being read from AGIPD temperature sensors has been identified by Gero (CAS) and the fixing is ongoing. 

Report of the XTD10 interventions from last week - Tuesday and Wednesday - C. Youngman 

Many thanks to those who contribute to the "SA3 'further technical coordination push" onTuesday (no-beam XTD10 closed) and Wednesday (XTD10 open) mini-shutdown, below is brief summary. The status items were not highlighted during PSPO's readiness meeting AoB section but are useful to know. Those issues that were raised are contained in the conclusion section. 

We leave the SA3 beamline with a functioning interlock, but you should additionally watch and test your component and ensure that beam operation is possible.

The principle task on Tuesday was

• for ITDM to shutdown and update f/w of the control server CPU hosts in the balcony room, and
• for CAS to replace the Karabo 2.1.18, running since the Oct-Nov shutdown 2017, with Karabo 2.2.1 which is already running on the SA1 installation. 
  • A number of problems during the installation were addressed and a stable deployment was finally reached early in the evening.

The principle task on Wednesday were

• test the updated GATT Ebara pump updated f/w and its s/w counterpart
• test that GATT Bronkhorst Mass-Flow valve f/w worked: correcting conversion errors and the incorrect setting of property r/w attributes
• test that GATT Inficon gauge f/w did not crash the loop and correct  conversion and r/w errors as with the the Mass-Flow valves
• perform Beckhoff-local tests on one or more the DOD motor axes as they were expected to be wrongly wired (as seen in the Jan-Dec shutdown in the VSLIT)
• update the s/w to reflect changes in the GATT f/w
• address difference in the s/w introduced by the move to Karabo 2.2.1

The key-point task listed above have been attained with the following caveats:

• There is a h/w fault which prevents the second Ebara pump being fully controllable remotely, it is currently locally controlled.
• Bronkhorst f/w and s/w is usable, the conversion is correct, but additional s/w work is required to align the s/w
• The Inficon f/w works (it does not crash the loop), the f/w conversion error is identified but not enough time was available to modify it.
• some s/w issues remain which are being addressed (tagging of Ebara, Bronkhorst and Inficon s/w, correct configuration of the vacuum-section..)
• the automatic update of project and scenes was not completely successful so project and scene owners should check and correct their scenes. The auto update procedure will be improved.
• Some data logging information was lost, but e now have regained a standard implementation (not hot-fixed) which should improve the this.
• After measuring that the DOD axes (1 of 10) were incorrectly wired it was concluded that all were incorrectly wired (as had been the VSLIT in the Dec-Jan shutdown)
  • Benoit and Daniele managed to rewire all 10 DOD axes during the mini shutdown and test 1 axis with Karabo.
• PES tests of multi-board digitizer s/w and f/w were continued (with measurements at the crate), these are promising as 'raw' and 'processed' data are now concurrently available.

In conclusion - good progress was made and this type of 'commissioning' mini-shutdown (anything longer than ~4 hours which includes somebody elses longer ZZ) should be performed as often as possible.

This requires

• that the photon run coordinator team know that there is a "list of task" to be performed which are not in the ZZ list
• that a selection of these tasks can be performed within the time budget of a mini-shutdown and that these do not compromise SA3 tunnel operation
• that the photon run coordinators inform the SA3 technical commissioning team (contact a member of the "SA3 tech coord" CAS team setup by Sandor, e.g. Chris, Valerii or Wajid ) so that they can organize the work in time (or report that they cannot as something or someone is not available).

During the next few days a "list-of-task" will be created. This could include technical commissioning actions for SA3: PBLM, ExitSlits, very end of beamline imagers where the status needs updating, etc.

Also remember that the CAS team tries hard to satisfy as many requests as possible, but prioritization will be done, so make your case thoroughly and don't expect it to simply happen (it has to be on the radar screen). In particular h/w, f/w and related s/w tests needing access will be done first and non-critical s/w work will be left until after tunnel closure. And remember to check your projects, scenes, and macros before you need them.
