=====Meeting Minutes February 10, 2012=====

===Present===
Betty, Suwat, Mike, Rachel, Bec, Jack, Dan--arrived when Bec began.

Bill: out of town

Zibi: sick

=====Group Business/Physics=====

  * Congratulations, Bill!
  * Room 124: Removed cabinets, tiles in floor have asbestos. Will be drilling into the floor, so need to remove asbestos from the floor.  Pushes back all lab moving?
  * Lee's experiment: maybe he'll decide not to take out DE's
  * Betty has a summer student coming mid-May.  Think about having him do a pin source calibration on Tilak's experiment
  * HiRA cans: Jimmy assembled one, Rachel and Betty looked at it; he'll try to set in the Si mechanical sample in the next one to check that it's right
  * TPC visitors here this weekend! Bec has a schedule up.
  * Bec: TWOFNR vs. fresco: corrections to how fresco input files read, new form for local-energy approximation, Now predictions between TWOFNR and fresco almost exact
  * Previously saw "discontinuity" in 3He cross-section, only in TWOFNR, corrected. Had a dominating spin-orbit term above ~70 MeV

===Jack: Efficiency===

  * "spreader function" in analysis code: where does it happen? Current guess: after merge when making physics files
  * Will ask Ali when he incorporated it
  * make randomization an option in the efficiency program, or a separate script to do it and then can be read by the efficiency program.

===Research Updates===
  * Mike: new gates on p,d,t from 50 MeV data. Not cutting into bands!
  * Rachel: dropping 3He because not enough dynamic range in the LASSAs. Looking at each CsI crystal, am missing some triton punchthrough, also have a lot of punchback in telescope 5 spectra... hopefully this will be omitted in the center-of-mass data when take cuts.
  * Dan: Proton vetoes not 100% efficient. Can we reconstruct missing events?  In 50 MeV: have lots more protons that are wall overflows than neutrons.  In 120 Mev: have way more overflow data than anything else.
  * Suwat: assembling from machine shop.. getting welded.
  * Betty: illustration: when using statistical models be careful of the assumptions that are made in the models. Also, be careful when using someone else's data, may not know all the limitations.
