Agenda

  • Rachel: status on mTPC digitization;
  • all: any other business;

Minutes

Discussions about mTPC digitization: SAMPA pulse actually slightly more complicated than APV pulse (APV assumes N=1):

 f(t) = ((t-t0)/tau)^N exp(-N((t-t0)/tau))

Questions/Comments from Nilanga:

* from GEMs (solid, sbs), the microscopic details do not matter that much;
* photons: some will hit copper instead of GEM foil. Photoproduced electrons have sizeable energies;

Questions from Steve:

* can we accomodate the pad size?
* having a constant number of pad as function of radius can really help in the perspective of machine learning analysis.
* Time for 1 million events? 1 h? (consistent with current sbsdig_lw speed) (need to define what is one event)

Question from Ed:

* Time of the sampling: when is the sampling started wrt the beginning of the pulse? needs to be randomized.


Question from Ed to Salina: Will she use the BNL FEC for the mTPC prototype? question of connectors ($15 each but can only be bought in large quantities), could be sorted out by getting "free samples"? Design of the card is needed to finalize the prototype design.
