STAF Detector Response

Turn PISA hits into :

charge on cathodes (Mathieson, Landau), add noise, put gains (and

pedestals) in --> ADC signals

charge on anode wire, add noise, apply threshold and latch

Apply zero suppression algorithm

Convert zero-suppressed data to “raw data format”

Apply gain, pedestal corrections to raw data, change N cathode samples to 1 (currently just constant gain and 1 sample)

Find cathode “clusters” and store; sort cathodes and anodes into arm, station, octant, plane

Initial fit of cathode clusters; add degradation for Lorentz, angle of incidence, non-perpendicular strips

Find C-A-C intersections, fit tracks, and make dimuon spectrum
