      Testbeam - David:
          Will do the alignment and see how far they will get.
          Plan on the google spreadsheet: https://docs.google.com/spreadsheets/d/1_oN0Z9fT_L3YjjUKPlpYYGW-0yCLTX6f-h3kN3rdoEo/edit#gid=922102466
          Test 4 different Matrixes of Run2020V5 -> Mask other parts (was tested and worked in lab)
          Rent car for going back instead of train. Can take back most important stuff to the lab.
          Rule for going back to institute unclear -> probably nothing important.

          6 out of 8 not working Run2020 Chips run for reduced bonding scheme -> bonding was the reason for high voltage breakdown on left side of pads.
          Something else that is going to be discussed at the coffee table...
      Sebastian Dittmeier:
          - Very quick test with Frontentbord
          Powerconsumption of 7,5W
          couldn't understand it correctly ...
          - Preparation for Bachelor defense
          - Temperature kallibration messurment in lab
          - cooling sensor with climate chamber
          - 2nd messurment to test if it was done correctly
          - iv-curves with temerature diode with turned of sensor -> callibrate temperature diode to the climate chamber's ambient temperature
          - sensor temperatur 40°C above gas flow (at testbeam), (10°C to 20°C are expected)

          - still testing probe card, issue with labeling some jumpers
          - checked all lines for crosstalk and data connection -> working
          - test probe card again this afternoon
          - to much pressure on some needels -> bending differently -> not aligning correctly
          - backup solution: bond 6 Mupix10 Chips -> test DAQ with complete module and fix probe card afterwards
      Collaboration Week next thursday -> Luigi is doing Update Presentation
