* MOSS design, Fred
 - new schedule
 - for IPHC, row steering, first version working -> now tuning
 - potential additional (small) blocs in end caps for IPHC -> discussion on-going
   such blocs might be interesting to gain expertise on the stitching (i.e. the fact that the sensor is large)
   => to be discussed in detail at next meeting
 - About DAC (Kimmo)
  o more systematic tests achieved, especially investigating temperature stability
    - one chip displayed some relative poor performance
  o dispersion of performance not known, would require much more chips and time <= we are not doing it
  o CERN keeps asking IPHC to dsesign DACs for MOSS => we keep answering NO

* MOST design, Szymon
 - no time from Szymon, task pending...
 - same feeling from CERN side

* Tests, Szymon, Serhyi
 o irradiation plan for DAC starting somewhere after 5 Oct
  - 3 chips of same variant split4-B (flavour D does not have DACs) => PRIORITY FOR BONDING
  - final doses expected: 500k, 1M, 10M
  - system (based on DAQboard) is almost ready
  - still need some shielding =>
 o About lab-tests of matrices
  - still only ONE setup for IPHC (will travel with Szymon)
    ==> NEED a MODIFICATION
  - 4 more chips (at least) split4-A/B/C/D to be bonded with new PCBs
    o then if more PCBs
  - these chips will be tested by Szymon AT CERN after DAC irradiation

* Test beam PS (18 oct - 6 nov)
 - mechanics
  o there might be an issue with the mechanical support => Serhyi ASKs CERN and probably relies on them
 - cables
  o missing USB-3 cables => probably need to buy
===> Serhyi to ask Miko what is needed from IPHC (both Hw and Sw)
 - Readiness of SW and FW for DAQboard (dependends on Valerio@Cagliari)
  o the situation is frightening, CERN has priority with APTS
  o Valerio will be
 - EUDAQ
  o produced -> Szymon
  o converter -> Yitao
 - Analysis for lab
  o Szymon has a ROOT tree with frames -> could be read by TAF
 - Issue of oscillation with carrier board
  o bricolage to be done on PROXYboard TODAY
 - Analysis for beam
  o Yitao will use Corryvreckan
 - people going to CERN
  Szymon 05/10 to ~30/10
  Yitao 11/10 to ~30/10
  Serhyi 25/10-01/11
  Jerome 01/11-06/11
 - Test plan
  o note that there is not much biasing choice, the nominal ones seem OK, just check outputs are in ADC range
  o Number of operational points
    - three voltages: Substrate and High and Reset
    => about 25 settings
  o basic 4 sensors from split4-A/B/C/D @ one temperature
  o trigger to accumulate per run: 10 to 50 thousands
  o 1st priority: Split4-B, Split4-A, Split4-D, Split4-C
  o 2nd priority: Split1-B, and repetition with other chips Split4-B, Split4-D
  o 3rd priority: irradiated Split4-B with various doses and settings
  o 4th priority: more irradiated Split4-flavors or Split-1

* AOB
 o Do we want to buy a TLU => no we don't

* TO DOs
 o Serhyi is organizing a discussion Thursday 30th with Miko to discuss some technical items related to test beam.
    After this discussion, Serhyi will confirm the feasibility of the priorities establish above for the test beam
     and then be able to write down this plan on one slide for the next WP3 meeting.
