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.
