      Present: Andre', Sebastian, Heiko, David, Annie, Thomas, Lars, Benni, Lukas, Alex, Adrian

      Minute-taker: Adrian (we go through the year in alphabetical order, first name)



      - shows pixel cell he layouted (see materials)
          - large transistors to achieve large input capacitance of amplifier (AC coupling)
          - output line creates large parasitic capacitances -> loss in amplitude (rise time not affected) -> routing needs to be changed

      - working on analysis of data from last testbeam (ATLASPix3)
      - installing software on new server (root6, quartus, ...)


      - working on firmware to include sorting for ATLASPix3
      - concept for frontend board cooling is progressing: heat pipes show promising results in first lab tests
          - Andre' suggests that results should be presented at next collaboration meeting and some relevant numbers should also be ready for PSI review

      - starting ATLASPix3 breakdown simulation studies
          - Andre' suggests to go for IR measurements in addition -> Heiko will contact Geneva guys about this
          - in general, investigation of the different breakdown voltages for the latest submissions is of high priority

      - reports about new tool for placing silicon heaters precisely -> results expected in the coming weeks
      - Andre' asks what is missing to produce modules
          -> some mounting tools need to be reproduced with the correct sizes

      - reports on status of flexprints
          - no solution for interfacing with insert yet
          - no layouts started yet
          - first step: decide on power groupings

      - plans the coming two weeks for handshakes with the responsible people so he can start writing his thesis
          - will set up cadence access for everyone

      - looking into voltage drops in front of the chip


      - will complete documentation on MuPix10 in the coming weeks
      - Andre' asks about serial powering tests -> could be tested with MuPix10
