      Minute taker: Luigi.

      Most of people are in HighRR lecture week.

      Alex: discussed with Bochum on Tuesday about probe card. Updated with minor modifications. 99%. Removed VDDD/A power regulator and legacy shift register.

      Jackob: trying to obtain results about the thickness from the shape of the efficiency curve. Derivative should be about Landau, then converted to thickness of signal region with ration between MPV and Landau width. Found a paper with more details about it. Cross-section corrections play a big role. Then writing thesis.

      Marius: just came back from summer school + vacation. Summer school good experience. Planning to work 2 days a week for the next 2-3 months. Will reprise working on tuning. Luigi offered to show the latest results he obtained. David proposed to make a testbeam box to use it in testbeams.

      Jan: moved the setup and reassembled it. Check if everything works again. Received Mupix10s from Benni. Next week might need help to set it up. Played with AtlasPix3: it takes up noise from peltier. Happens when connecting to Arduino. Need isolation?

      Heiko: no news. One measurement needs to be done on Mupix10 in lab. There might be a signal loss. AmpOut is consistent with Mupix8. Somewhere afterwards signal is reduced by 50%. Proposed a series of measurements to Luigi. Possible reasons: one decoupling capacitance different, and ___. The new values don't look bad, but there might be some filtering effects. Benni also volunteered to check with simulations. If we really have problems there independently on other issues we saw, we need to verify it before finalizing Mupix11. It might be not a minor change. We should do simulations and lab tests. It won't solve all our problems, bur we can recover part of the signal loss.

      Sebastian: in contact with Mainz to understand the rates at their testbeam. Found a bug, already fixed. Problems with running PixelAna. Jackob proposed to come over and check offline.

      Luigi: helped Mainz in testbeam. Few organizational things. Organizing return of chiller from PSI IntRun. Jan: news from AtlasPix3 thinning? No, but it might be good to do it by DESY testbeam.
