Transcript High energy muon analysis (Wai and Chekhtman)

High energy muon analysis
Larry Wai and Sasha Chekhtman
External Trigger from
Scintillator Coincidence w/ 50cm Pb
CAL_LO only trigger
Data sample size
 3.7 Hz external trigger rate
 Goal for calibration is 1000 selected
events / 3 mm


From 16k external triggers (1.13 hrs), selected 3
events / 3 mm
This will improve by factor (~2?) when using TKR
information for selection (Sasha is investigating)
 For livetime factor of 0.9, need 188 hrs of
data taking; 176 hrs are scheduled
 Sasha will also fold in CAL_LO triggered data
already collected (72 hrs) after checking for
differences in data samples
