Tail Catcher/Muon Tracker at DESY & FNAL TB Facilities Northern Illinois Center for Accelerator and Detector Development Northern Illinois University and Deutsches Elektronen-Synchrotron (DESY)
CALICE TCMT (Tail Catcher/Muon Tracker) Provide a reasonable snapshot of the tail-end of the shower for simulation validation Prototype detector with high-fidelity to what is imagined for a generic LCD correcting for leakage understanding the impact of coil muon reconstruction + PFA fake rate Designed to test new detector technology (Silicon photomultipliers) for the ILC

CALICE TCMT Calibration data showing single Photoelectron separation Moved into the facility 3 rd week of Feb. Took beam in the last week ~ 5 days Took 120 GeV/c protons, 16 GeV/c (mostly pions) and some beam dump muon runs Calice DAQ Electronics chain reproduced and tested Raw ADC count from 120 GeV proton beam On Avg p.e./mip
Pedestal subtracted noise signal
Plans Participation in the combined test beam at CERN. Approximately 1 month (August-October) of beam time Followed by longer tests at Fermilab in 2007
