previous meeting << >> following meeting

Agenda

Thia kindly requested status/updates on:

  • simulations - Rachel, Carlos
  • tracking - Steve, Arun
  • target - Dipangkar
  • GEM/streaming DAQ - Ed, Eric P.
  • mTPC - Nilanga, Kondo
  • LAC refurbishment - Dipangkar, Simona
  • SAMPA chips - Sao Paulo, want to give an update?
  • Cerenkov modifications - Andrew, Eric F. any news/thoughts?

Minutes

Attendees: Bogdan, Dipangkar, Jan Bernauer (Welcome), Marco B. Nilanga, Paul, Steve, Thia, Arun, Carlos, Ed, Eric F.

  • Simulations updates/discussion:
    • Carlos: g4sbs part about mTPC will be reorgainzed; almost has all the interesting background processes (some been provided as structure functions only, not cross sections), now need to include them in g4sbs;
    • Arun/Steve: been busy (with Hall C activities) but will be able to resume shortly;
    • Rachel: will wrap around conical chamber wall study + will focus on estimate trigger/electron rates;

Discussions will be made offline about when G4 simulations, digitization and tracking will need to come together.

  • Target (Dipangkar): Target bust at 80 psi absolute = ~5.5atm (NB: we want to run at 4 atm~60psi), /but/ there was a flaw in the gluing of the target tube to one flange, which is where the target busted; will try again with flawless gluing + will test lower pressure values before testing 80 psi.
  • Electronics updates/discussions:
    • Ed: Progress (see document) currently at step (C); will probably use SAMPA in non-continuous mode (triggering);
    • Marco: Infos about newer chip: shaping time can be configured to 80 or 160 ns;

Discussions about triggering mode: trigger rates are (roughly) estimated about 20kHz which for the SAMPA chip is low; number of samples recorded after trigger is programmable.

  • mTPC prototype (Nilanga): will be delayed + will need input from simulation team (number of pads, conical wall, etc);
  • LAC (Dipangkar): there was a leak in the LAC (a light leak I assume);
