Gwyn – TMS Optimization (–20 min)
some clarifying questions on the slides/talk
(Tom LeCompte) horizontal strips in front seem to help most in lower energy range (~250 – 500)
(Tom Markiewicz) question for geometry used here, dimensions / air gaps?
(Andrew Furmanski) what is the steel error? → where did the particle actually stop / how much steel did it go through after the last registered hit
some discussion on why and where this is going to be useful
( Steve Manly added in chat) For Gwyn's study: we used 200mm passive argon followed by a cold membrane and window with 62.8 g/cm^2 on average. We used a distance from the downstream edge of the ND-LAr cryo wall to the first plane of TMS to be 1025 mm
Kate – Track Matching Update (~20 min)
some clarifying questions on the slides/talk
source of off-diagonal portion of lost momentum?
(Jeffrey Kleykamp) bug in position LAr End position array? → remake plots with correct value in arrays used
Discussion after talks
Tom LeCompte: Light yield from test piece is very high (~40% brighter than Mu2e scintillator, ~125 photons per MIP) → Bragg peak can be dissolved? Energy could be differently handled in code
Could this scintillator be distributed to other groups/institutes for testing?
Jeffrey: Who is writing about studies in the PDR?
Asa: ND prototype workshop, who is going? → Liam, Asa
