Subject: Status and plans after SASE1/3 Readiness Meeting 

General:

  • The length of the shut down in October is still under discussion. Currently it appears that it is shortenend to 8 working days
  • The management reviewed the readiness of the instruments for first users on 14 September:
    • Very good progress was made over the last weeks
    • Data was taken with both large pixel detectors
    • A few "red lights" remain
    • In spite of the remaining difficulties, the first users will be invited
    • However, the Management shall inform the first users that they will get another beam time in March in case the experiment objectives cannot be reached
  • The second  call for proposal will only cover 5 weeks in May/June
  • The third call will start on 6 September for all 6 instruments

FXE

  • van Hamos was aligned for the Cu K_\beta line (required for the 3rd exp)
  • XRay emission was observed on the GreatEyes detector
  • Work is still urgently needed to get the Gotthardt Detector working 
  • The laser is synchronised to 100fs. It is currently up to the shutter in the instrument hutch

SPB

  • On Monday AGIPD took first data  with 30 frames 
  • The sample jet is working with sufficient vacuum to operate the detector
  • Yesterday, everything was ready to take data with liquid jet and AGIPD. Unfortunately, there was a major software/electronics failure that lasted for 6.5h
    • A fuse was blown in one crate needed for the train IDs (single point of failure)
    • This affected all crates and KARABO
    • A fallback is currently being implemented
  • The door interlock could not be operated because there was a problem with the operator password

Tunnel

  • SASE3 tunnel installation will not be reviewed because there is no work on it
  • SASE2 tunnel installations will be reviewed once AE and CAS get involved.
  • Network installations may take up to 4 months (info by K. Wrona)
  • First signals were seen from HIREX last week
  • Currently this integrates over 30 bunches as Gotthardt is not available

Laser

  • Differently from what was reported earlier, the AC system works at the required lower flow rates
  • Progress on laser installation and commissioning is progressing as planned
  • There are a few problems with motor operations from KARABO

Detectors

  • Both AGIPD and LPD are taking uncalibrated data
  • A cooling leak was detected in LPD. Experts from RAL are going to look at this today
  • Calibration may just be achieved for AGIPD. Probably not for LPD due tot the HW problems

AE

  • All SPB loops were updated to accommodate the train ids
  • Almost all FXE loops were updated too
  • The tunnel loops were not updated yet. 
  • For the tunnel, the motion loop needs to be updated. EPS and Vacuum loops should remain unchanged
  • There remains one open issue with an encoder on the sample injector. X and Y encoders will be exchanged today to isolate the problem

CAS

  • Work this week concentrated on GUI issues (achieve faster feedback)
  • One patch was released to fix GUI problems
  • Good progress was made with data analysis tests together with people from CFEL
  • Next important topic on the list is to get the XGM data into the KARABO DAQ stream. This requires the DOOCS interface
  • KARABO 2.1.16 needs to be closed
  • For FXE there is good progress with Gotthardt. This now needs testing in the hutch. The same applies to the digitizers.
  • W. Wrona points out that independent KARABO installations exist for SPB, FXE and tunnels. This needs to be fixed to allow DAQ integration.
