Description

working group meeting place for DarkSide-20k PROTO

Status of proto-proto:

  1. 4 fiber-bundles ordered; 3 of them have 2m inner length and 4m outer length; one bundle contains 76 fibers and is thus sufficient for proto-proto; available in 2 months;
  2. receivers: crate ordered, receivers ready to be tested;
  3. steering module will arrive at LNGS by mid February
  4. first MB ok (but SiPM single dose, low uniformity)
  5. second MB delayed due to late arrival fo SiPMs from FBK run #4 (now expected in first week of February); it seems still possible to have the 2nd MB ready by end of February; the SiPMs are triple dose, high uniformity
  6. TPC: Clevios painting received at CERN; tests will start next week (mechanical resistance, electrical conductivity); tests on two sided wires to be performed at Houston will be reported at next meeting; updated design to be finalized only after test completion; once it is available it must be sent to Bologna in order to finalize tools for MB;
  7. test set-up at CERN: in Francesco's lab; HV feed through to be collected at LNGS; purification loop ok
  8. DAQ: VME crate ok; 5 V1725 boards in TRIUMF; optical interface being shipped; TRIUMF will provide DAQ server, need to organize shipment; order placed for analysis server and disk storage; TRIUMF also finalizing trigger box; MIDAS can interface to slow control; 
  9. need to cover slow control task
  10. Power supplies and filter boxes not yet available (Alessandro R.)
