sPHENIX Event Plane Detector discussion

[Jamie Nagle <jamie.nagle AT colorado.edu>]

Hello Ejiro and Brennan (cc to the sepd list),

Dan and I are going through the mapping of ADC boards into groups with XMIT transmitter boards.     In order to optimize the limited number of boards, it would be very helpful to have hit information from simulation for the sEPD.     Ideally, depending on radiation damage over time to the SiPMs, we would like to zero suppress below the single particle hit level (MIP). 

For Au+Au minimum bias collisions, can you provide a percentage for tiles for when they have >= 1 particle hit (based on cutting at 0.4 * MIP) and hence the percentage of the time a tile has zero hits.

Since this percentage will only vary radially, one can just have a list of percentages for the 16 different tiles going outward.

Thanks in advance,

Jamie
