      Present: Testbeam crew @ DESY, Frank, Annie, Alena & Ivan, Andre, Benjamin, Alex, Adrian, Sebastian

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


      • Ivan:
        • Operation of ATLASPix3: VSSA should be optimal at 1.2 V instead of 1.0V, for maximized AmpOut signal
        • With lower VNPix should also use lower VPLoad, but then amplifier is slower, time resolution could be worse
      • Andre:
        • Full parameter scan will be done at PSI in June, but test now @ DESY what's possible
        • Time structures in the noise: question to Ivan, can noise be induced by counters?
        • Ivan's response: Should be seen @ AmpOut, crosstalk digital to analog possible, but not seen in previous chips
      • Thomas:
        • Lowest threshold we can achieve is 60 mV (Ivan mentioned 70 mV, so this is fine)
        • Will do @Desy tests with settings sent by Ivan
      • Alex:
        • Probe card for MP10 close to be done
        • Will start with insert afterwards
        • Andre: schedule discussion for Tuesday, short notice
      • Sebastian & Andre:
        • Sorter for AP3, quick fix (waiting for readout latency plot, could the range of TS to sort be set via registers?) or go for a new version?
        • Check with Nik what's already there, maybe it's worth to go directly to a completely new version
      • Luigi:
        • Integration testbeam, discovered "feature" of Midas, word alignment by 8 Bytes, but data format did not respect this
        • Lars met with LTU @ GSI, discussed plans, LTU can do in parallel flex for single MP10 and for the ladder
