Subject: Status and plans after SASE1 Status/SASE3 Readiness Meeting 

General

  • The rack layouts and rack placement were finalized during the PRR in August. The result is the basis of the network planning. The network is currently being installed and will most likely be finished by the end of the year. Changes to the layout that affect the network planning are no longer possible. 
  • The TC/XHEXP1 meetings shall be combined into one bi-weekly meeting starting on 9 Nov. A separater new invitation shall be sent

Instruments

  • SPB
    • Currently preparing for the next user period
    • A lot of work still needs to be done for bringing the laser to the interaction point. This mostly concerns the beam pipe
    • Apparently there was an interlock problem related to SPB components in XTD9. SPB components were taken out of the EPS loop without SPB being informed
      • Comment from T. Freyermuth: The condition of SPB devices was preventing beam operation and noone of SPB could be reached
  • FXE
    • A lot of progess was made together with CAS
    • This afternoon a DAQ stress test with several detectors is planned
    • The encoders on the CRL lens stack were disabled as this complicates the operation at the moment

Tunnels

  • XTD9 was closed yesterday. Beam could arrive this weekend
  • About one shift worth of work remains in XTD10 before readiness for lasing
  • KMONO measurements took place on Wed/Thurs from 3PM - 3AM
  • Some DAQ and KARABO issues surfaced
  • But it was possible to record donut radiation patterns
  • Now commissioning of HIREX is being prepared
  • XGM requires some minor re-commissioning

Laser

  • Beam is in the ILHs. 
  • Still problems dealing with the capricious AC system
  • The promised specs of the laser beam are met
  • Synchronization is still to local timing. Synchronization to the machine timing only comes next week and no time remains for testing before users

Detectors

  • LPD:
    • 15/16 super modules are operational
    • This week calibration data from charge injection were taken
    • The detector is ready for users
  • AGIPD:
    • Detector is fully working again after a big rearrangement of cables
    • It was found the the clocking-control cable is too long and needs to be re-routed during the winter shutdown. The detector will be fine for the next users
    • Work is ongoing on the firmware in order to allow 30 frames/train rather than only 15

Electronics

  • SPB:
    • Updated the tunnel loop for SPB
    • Loop 12 is up-to-date
    • Loop4: The mirror mounts were tested locally
    • The is no feed back on interlock behaviour in loop 5. If there should be problems individual conditions can be disabled
    • For loop 7 zoom and focus and mirror mounts to be tested
    • Same applies to loop 2
  • XTD9:
    • want to update EPS loop to include removed SPB components today
    • Vacuum loop to be updated next week
  • XTD10
    • Some ion pumps show an error condition in KARABO. J. Tolkiehn is investigating

ITDM

  • User handling for log books has changed. Please consult the help log book for details or consult J. Szuba
  • The meta data catalogue was updated so that instruments can now annotate with their own credentials
  • Folders for the next two user proposals are created, also in the online environment
  • A new version of the DAQ software needs to be deployed in order to fix a bug in slow data daq

CAS

  • A number of issues need to be resolved with Diagnostics as already mentioned earlier
  • The Gotthardt Detector is now working in FXE
  • The promised reduced scope for the scantool has been achieved. It will be made available to the users asap, most likely today
