General

"In the beginning of this meeting SM congratulated the whole staff of the European XFEL and in particular the commissioning team with the very important achievements 
- the first SASE3 lasing / bi-lasing at SASE3/SASE1. It happened yesterday late evening. More information will be given during our PBS meeting next week."

Photon Run Coordinator Report to Readiness Meeting

• parasitic operation in SASE3 (closed 3 undulator segments) for photon commissioning with SR-beam
  • V0 opened, vacuum open down to XHEXP-shutters
  • photon beam detected down to FEL imager, yesterday until SR absorber beyond mirrors M1/M2 and MCP
• photon systems supported tuning/search for SASE1 lasing
• Progress in SASE3: 
  • First Lasing in SASE3/XTD10 
  • simultaneous lasing SASE1 and SASE3

SPB

• During operation Karabo crashed. The problem is not clear yet. Det. loop was affetcted ==> AGIPD tests stopped!
• 2 mirrors in D.02 are being installed.
• Test of the mirrors movements is ongoing
• Motors issues are being checked by AE (Mahadi)

FXE

• Gotthard det. and digitizers back to work
• Leak close to the diamond window being fixed

Laser:

• Timing system has been upgraded - currently we can have any repetitive laser pattern for each laser, number of laser pulses in not limited to number of electron bunches, also we can have lasing when there is no x-ray (electron bunch)

•  Installation according to the plan, no major delays. No commitment to experiments for laser availability in March.

Vacuum

• SASE2:

  • XTD1 under vacuum up to XS2 shutter

• SASE3: 

  • interlock problems solved, runs without problems since yesterday

  • GasAttenuator loop needs update. when is the best time to do that? to be agreed with PRC

Optics

• issues mainly in the XPD section 

XPD

• SASE1 : photon systems supported tuning/search for SASE1 lasing
  • tests of DAQ in SASE1 ongoing
• parasitic operation in SASE3 (closed 3 undulator segments) for photon commissioning with SR-beam
  • V0 opened, vacuum open down to XHEXP-shutters
  • photon beam detected down to FEL imager, yesterday until SR absorber beyond mirrors M1/M2 and MCP
• karabo update to 2.2.x in SASE3 tunnel scheduled for next tuesday morning
• SASE3 DAQ urgently required
• issues with in-vacuum goniometer motor control of KMONO
• issues with IMGFEL to be understood - found a scintillator which works when we have FEL radiation

AE

•  The need to properly plan the activities close to the tunnels closing is pointed put.
• The need of a specific technical coordinator as in SASE3 for the SASE2 tunnels is pointed out

ITDM

•  Sase3 DAQ not ready since Karabo is not yet up-to-date
•  Slow data acquisition issue affecting cameras: being worked out.

CAS

•  In SASE3, deployment of new (2.2.1) Karabo versionwas  delayed because of many people getting the flu.
•  2.2.2 release test cycle ongoing
