Agenda
- Hybrid calorimeter simulation update
- Proposal draft
Minutes
Attendees: Liping G., Sascha S., S.T.
- Liping is working on the introduction and the physics update for the proposal. We will only be focussing on our responses to the PAC's questions.
- Sascha presented his latest simulation results. We decreased the size of the insert from 1.2x1.2 m^2 to 1x1 m^2 but increased the beam energy range and therefore the flux by about a factor of 2 relative to the original proposal, so we anticipate a similar yield of π0γγ events. The signal/background ratio depends on how many photons are detected in the insert. The sweet spot seems to be when at least 3 of the 4 are in the insert. The efficiency is quite low (<2%) if we require all photons be in the insert.
