      Minute Taker: Sebastian Preuss


      David/Luigi (Testbeam-crew):

      • Checked all powering configurations, works

      • Tested 2 sensors, three more to go

      • Will finish in the given time

      • 2 chips do not work → 4/6 chips working

      Benjamin/Heiko (Run2020 summary):

      • Only one sensor available, three more glued, not yet bonded

      • Delay on inserts

      • Can see data, no AmpOut or Hitbus yet, unable to mask pixels → Heiko and Benjamin looking into it

      • Chips from Optim arrived, one wafer picked yesterday (30.09.2020)

        • Ivan was asked if he needs some of the remaining chips

      • Inserts expected to arrive on friday

      • V5 ready to be tested, but masking would be nice to have (not working yet)


      Round table:


      • Will give prep talk on Monday at 11:00

      Sebastian Dittmeier:

      • Next week, new FEBs will arrive (coils still missing), will be tested, some go to Mainz


      • Designed PCB which arrived yesterday, chips were bonded, will look at firmware


      • Development of FEB for december test ongoing

        • Needs more input for being able to continue


      • Work on Run2020 ongoing

      • Waiting for Master thesis result


      • Testbeam


      • Fixing grammar and incorporating feedback in thesis


      • Working out how to go to Germany due to COVID

        • Rules at DESY will be updated today


      • writing at the moment and continuing some software work


      • No digital hits, AmpOut, hitbus → Maybe sensor is damaged


      • Writing on thesis

      • Some result overview (see presentation)


      • Organizing transport (see Mattermost for pictures etc.)

      • Glued last letter

      • Will bond second-to-last ladder

      • Will finish outer half shell this week

      • LTU’s HDIs look good in quality, thickness same as before, optical check says they’re good, also under the microscope; connectivity will be tested

        • length matched really well (~20-30 um accuracy)


      • Testbeam and related work


      • ETH Zurich started tests with longer cables, results expected within next two weeks

        • different driver than the one we use

        • Results needed in order to decide what is needed for a new MuTrig

      • Magnet cooldown still ongoing on PSI

        • coil at ~170K

        • cooldown at expected pace, will take ~10 more days

        • Vibrations of coolers have to be looked into, will probably be investigated further beginning of next year to then determine appropriate dampening solution

      • Working on sensors for the experiment (temperature, humidity, pressure, …)

        • Difficulty due to different interfaces, maybe a change of specification is needed

      • Two new students, one working on helium filling process, one on expansion

      • Design of upstream beampipe at PSI started



      • HVMAPS consortium will end mid next year (2021)

      • Will contact some people to write new applications (due 01.11.2020)
