Status and plans after SASE1 Status/SASE3 Readiness Meeting |
|
|
General
- User operation is delayed by 48h due to rocky startup of FEL.
- FEL still has not reached acceptable levels of stability and power
Instruments
- SPB:
- Instrument was brought back to a somewhat running state
- There are still problems with motors in the sample chamber
- Alignment with beam is ongoing at this time
- FXE
- New scan tool was tested
- Currently working on user-specific alignment tasks
- Laser was routed to the sample position
- The beam is still drifting around
Tunnels
- FEL had trouble to find lasing
- There was a controled access on Wednesday to fix various problems. However, further problems appeared
- It was decided to roll back the changes made for a new injector laser, but this did not improve the situation
- At some point 400 uJ were reached and lost again
- There are many problems with the undulator system
- Incorrect values in lookup tables
- Difficult operation of the entire system
- FXE should be able to start up tonight
- SPB would follow Saturday morning since time is needed for alignment during the day today
- Shifts for photon diagnostics were largely cancelled due to FEL problems
- KMONO gave some interesting results pointing to the problems in the undulator system
- Next week FEL Imager and KMONO will be installed in SASE2
Laser
- Both SASE1 instruments have laser beam with local timing.
- Tests with machine timing start today at lunchtime
Detectors
- AGIPD is in best possible state.
- Firmware and DAQ were upgraded
- Some commissioning time with beam is needed today
- LPD had a cooling leak and a power problem last night
- At 6 pm yesterday, this was still not fixed
AE
- Continuing small activities for user operation
ITDM
- A small bug was found in the DAQ that affects only slow devices with certain train ids
- It is proposed to fix this during the next break. Decide on this Monday
CAS
- Dedicated squads for the setups of SPB/FXE, DOOCS integration, Scan Tool closed now
- Tools delivered but with significantly reduced scope
- All necessary things for DOOCS Karabo integration were delivered. Now waiting for DESY
