General

• First users have done experiments - despite the current problems it appears as if everybody was able to take some data for future publications.

Short Report from SASE1 Instruments

• ​SPB (A. Mancuso): 
  • ​Beam was lost due to incident with electron beam hitting & damaging components downstream of the northern dump.
  • Currently only single bunch operation
  • Lots of work to be done in Oct. shutdown, Adrian will provide a list to Thomas Tschentscher
• FXE (T. Tschentscher):
  • ​Problem with the Tangerine-laser affects PP-experiment ==> to be fixed on Tuesday
  • Consider to switch to oscillator only until then ==> lower repetition rate, lower OL pulse energy
  • Next experiments require Gotthard & LPD in parallel operation ==> merge Gotthard & LPD to same run control next week before user run.
  • Today, test with DAQ and Gotthard was successful, but Gotthard has never seen XFEL X-rays so far. ==> Test with beam could happen potentially Monday night (instead of user experiment)

Tunnels (M. Dommach, J. Grünert):

• SASE1:
  • Few issues with XGM, have been or are being solved.
  • It was suggested to put the Hirex-grating into the beam while FXE is taking beam to measure / commission parasitically. But it appears next week neither Naresh nor Jan will be available.
• SASE3:
  • ​Due to the electron beam incident the first vacuum sections have been vented, there is most probably a hole in the V0, but only Rad. Safety to access the tunnels right now. ZZ/Access by anyone else only after clearance through SRP - working there is probably only possible in Octorb
  • Beam did hit the beam pipe apparently just upstream of the transmissive imager. Imager and further (vacuum) electronics seems to have been damaged in the upstream part of XTD10.
  • Due to this incident, it should be reconsidered if dosimeters are required in XTD10, too. SRP did unfortunately not participate, and thus was not able to comment.

Laser

• Working still on improving the laser
• Issue regarding motors coming back to their position is most probably a firmware/options issue

Detectors

• AGIPD:
  • ​According to Yolanta "operates better than expected"
• LPD
  • ​Also operates better than expected
  • Configuration of LPD is getting messed up by people working in parallel / unclear status of the detectors Gotthard & LPD ==> There should be a responsible for the detector, who is present in the control room and can allow remote access to work with the detectors / run configuration. ==> These steps should be well-documented in the FXE-Logbook.
  • K. Wrona: Next week will be better with just one run controller.

Electronics (P. Gessler)

• There is an issue with some motors & encoder @ SPB.
• AE will finish the work on the last loops in SASE1.
• WP79 needed & got support by AE.

ITDM (K. Wrona)

• DAQ for the tunnels is setup. ==> XGM-run control for the tunnel is to be tried.
• Slow data: It is an issue how and how fast to store slow data (lots of properties which do not change).

Software

• FXE:
  • Still daily meetings, prepare LPD & Gotthard
  • Working on GreatEyes, too
• SPB
  • Configure slow-data cameras
  • Laser project is running in CAS
• SASE3:
  • C. Youngman is the CAS-responsible, should collect requirements to compile master equipment list for SASE3 ==> to be compared against MEL SASE1 to identify additional work required.
• SASE1:
  • Loops & Karabo will be updated together.

October Shutdown:

• SASE1
  • No major items here currently, focus is on SASE3 / XTD10.
• SASE3
  • First priority is to get all items required for first lasing up & running ==> Vacuum system including anything up to the absorber.
  • CAS is starting to set up Karabo and all controls.
  • ITDM will also start to work, but does not require access to the tunnel.
  • C. Youngman to generate MEL from input from the groups ==> invites to a meeting if necessary.
  • Eplan for PES will not be available on time ==> has to be pumped in a provisional fashion.
