Subject: Status after 0930 meeting 

General

  • Recomissioning of the FEL has been bumpy and up to this point only very weak lasing could be achieved. 
  • So far SPB had only little beam and FXE had no beam at all. Both instruments state that the commissioning time for the up coming user run is insufficient

Instruments

  • FXE:
    • First SW and DAQ stress test on Friday went well.
    • Some problems appeared with the slow data that should be fixed by now
    • K. Wrona states that these problem originated from missing permissions due to change of userid
  • SPB 
    • Entire instruments needed re-alignment with beam since the CSS was moved during the shutdown
    • Very low intensity and not very stable beams were available on the Weekend. The beam could not be properly focussed
    • The bender for M2 cannot reach the flat condition. Is this the temperature problem again?
    • One pump was overheating
    • AGIPD tests with new bunch patterns started this morning
    • Significantly more time needed before user operation
    • There were some problems with the interlock system that trigger beam aborts

Tunnel

  • Commissioning program was very limited in the last few days
  • KMONO got some first interesting results
    • Rings and Kicks could be seen
    • Some wrong undulator settings were identified

Detectors

  • Firmware update was done to record all 30 bunches. However this still has problems
  • Need beam for calibrations
  • The planned update by ITDM of the DAQ was not yet done

Advanced Electronics

  • The mentioned interlock issues in SPB require an update to loop 7
  • In loop 4 need to reset the "all valves open" signal by hand if it trips
  • The SPB Master loop needs updating both for MPS and timing

Software

  • Tests of the scantool took place with hardware. These tests continue today
  • A new data model is being worked on for the scan tool but this is not available yet
  • SPB states that at this point they will not make use of the scan tool as they first have to consolidate the instrument
  • FXE is involved in the CAS tests

ITDM

  • As mentioned before the DAQ version is still old and needs an update. This contains many improvements
  • IBM discovered a bug in GPFS and published a patch. The bug could lead to data corruption
  • Decision: DAQ update and GPFS patch will be installed today in the morning.
