HEC Beam Test Primer• Production modules of the HEC have been tested
in particle beams in 1998, 1999, 2000 and 2001– Lots of data (electron, pions, muons, 6 to 200 GeV)– Pulse shape sampled for many 25ns time samples– Calibration parameters obtained from special runs– Signal peak reconstruction parameters obtained from
noise measurements and knowledge of pulse shape– hec_adc software framework– NIM paper accepted for publication
• Getting ready for combined beam tests– HEC/EMEC scheduled for August 2002– HEC/EMEC/FCAL in 2003
