Subject: 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
