* CE-65 Test, Szymon, Yitao, Serhyi
 - current test beam is mostly used to get the CE-65 system running
   o there is not yet a good connexion with the telescope-trigger
   o Szymon does not understand very well the small amount of data taken
 - Sergey will bring back one DAQboard from CERN at the end of this week
   o lab test will start (hopefully) from November 2nd
   o for data analysis, we still need to connect rawdata format of lab sw to someting, probably TAF (Jerome)
   ! Szymon has to switch to design, test team will be essentially Serghyi, Yitao (Jerome)
 - target beam at DESY from 29 Nov. to 6 Dec.
   o we skip SPS beam 10-15 Nov.
   => Jerome writes a mail to Miko to crosscheck this is reasonnable
 - Some discussion on the plots posted on Mattermost (https://mattermost.web.cern.ch/iphc/channels/ce65-beam-test)
   o backbias -3 V
   o AC high-Voltage 4 V
   o conversion factor measured with external voltage O.O5 mV/ADCU
   o no clear conclusion
 - Plan the message for next WP1.2 on Wednesday 3rd
   o prepare 1-2 pages with plots for the DAC (nothing on irradiated chips)
   o prepare 1 page with a positive message about CE-65 but no results (except for the scope image)
      => Andrei
 - STRONG comment by Andrei: we need to assess at least one version of CE-65 works before designing CE-65++

* MOSS, Fred
 - still working on the vertical PE
 - debugging the digital flow with Pedro (@CERN)
 - seems that the 6 metal layers will be available but no new kit availble...
   o note that 5th layer reserved for power
 - mock GDS file to be ready by end of November 2021
   o only realistic if metal layers do not change...
   o expect long feedback about stitching with Tower
 - two options for the pixel (18 and 23 um) still to be chosen
   o front-ent from DPTS (CERN in charge)

* CE-65++, Andrei
 - design is starting again
 - pad ring with new features (power supplies) already there
 - we need to re-discuss the various options for next meeting (below a few hints already)
   o need to include the 2 pitches from MOSS
   o we can keep same pitch
 - we don't know yet if the process will be modified (doping profile, ...)
   o we can submit same sensors as CE-65 in that case

==> next meeting Wednesday Nov. 10th at 10h30
