General

• User operation ongoing in SPB/SFX and FXE

Instruments

• FXE:
  • User operation started during the night
  • Some concerns over running LPD as the sample chamber is from diamond and direct reflections could cause damage
  • Generally instrument worked very well
  • Synchronization with PP laser is now in a state where it can be tested
• SPB
  • Many data taken for detector calibration
  • Severe issues with KARABO
    • Response is very slow
    • Major crash this morning
    • Detector controls complex and instable
  • A failure of AGIPD related to FPGA not understood
  • Strange interlock issue: EPS interlocks appeared disabled

Tunnels

• L. Samoylova spent many hours on Wednesday to set up the DAQ in the tunnel
• With the help of many support people she managed to get the system to work
• The system is instable and also seems to record many more parameters than are needed
• Use of the system is very clumsy
• Comment from ITDM (L. Maia): The data sources were specified by the users. It is acknowledged that the system needs a lot more work
• Diagnostics is working with CAS in a squad to work down a list of open redmine tickets
• The DOOCS - KARABO bridge is now working. The FEL imager is routinely available in DOOCS to the BKR crew
• DESY set up a statistics server to help collect data about beam pointing instabilities

Laser

• Local pattern generation synchronized to machine timing is working
• Overlap finding together with FXE was done but has to be tested under real condition next week
• A few suddent shutoffs of the front end occured. The origin might be understood
• There are large timing drifts in the ADCs that are currently not understood (up to ms)

ITDM

• Next Wednesday there will be a 1h shutdown of the load balancer in the DESY RZ. This should affect mostly the web services
• It should be noted that the DAQ ran quite stably in SPB and FXE. More than 20 runs were collected in each case without a restart

CAS

• Two hot fixes are out (2.1.18.4/5). These address  very specific issues
• A major new release (2.2) is planned for the winter shutdown. This will be mandatory
• Comment from instrument: It must happen early so that wrinkles can be ironed out!)
