      Discussion about Demonstrator testbeam (PSI Dec 20)

      Luigi can you put summary here?


      Round Table:


      • Had
      • running low on 100 µm thin MP10 --> order new? or just go with 50 µm
        • Luigi: Plan only use 50 µm for demonstrator
        • Thomas: Maybe test 50 µm on insert without cutout
        • Heiko: or use Kapton as support also on insert
        • Andre: Need to thin and dice anyway because there are orders from other institutes (Bochum). So, we could get more 100 µm sensors

      Sebastian D:

      • Working on small loop-back card for FEB
        • quick testing of FEB
        • more or less done, can be submitted in near future
      • clean up of device code repo started


      • working on firmware of counter chip


      • storage space?
        • recommendation: compressing data should be easily possible to reduce storage to 1/3
        • David: How long does it take?
          • 2-3 min for 100 MB files
          • decompression should be faster
      • beside that resting from test beam


      • Working on 2020sensors:
        • v2 without any problem for new sensors
        • v4 since yesterday working (reduced freq and changing DACs)
        • new bonded and glued sensors ready
      • Which sensor should be used in test beam?
        • three sensors are working in single setup which would be ready for beam
        • 125, 62.5 as freq are usable (David) considering the one sensor with problems


      • 8 more 2020 chips can be tested
      • What should be the work for Florian? (since Benjamin is not around for 2 weeks)
        • Luigi: not with Alex (he has priority on adapter card)
        • Alex: disagree (would work on 2020 if possible)
        • David: No sensor available in the next 2 weeks
        • agree on topic after the meeting


      • organizes test beam stuff
      • packing on Saturday
      • workshop will bring the stuff on Sunday to DESY
      • crew comes with train
      • setting up on Monday (group before measures until Sunday night)


      • writing thesis


      • Quarantining in Hamburg before testbeam
      • fly goes tomorrow and takes a test at the airport
      • Status of Zach is unclear



      • writing and producing plots and evaluation scripts
      • bussy with coding


      • looks like at DESY is only a non-working sensor
      • software: redone sensor class
        • David: When should it be merged?
        • Last commit will be done now-ish
        • David will test it later


      • Preps for Colloq (28th October - 1:30 PM) and upcoming testbeam


      • bussy writing (handing in next Friday)

      Sebastian P:

      • comparison measurement set up in basement
      • irradiation vs. no-irrad but time
      • current measurement uses no source
      • analysis while running should be possible starting tomorrow


      • buying HAMEGs
