Description
The authors present results on the efficiency and performance of the ZEUS detector Calorimeter First Level Trigger (CFLT) using data taken during the 1993 HERA physics run. The CFLT is designed to process events in a digital pipeline applying pattern recognition algorithms and fast digital summation techniques in order to collect interesting physics events and reduce background from beam gas interactions. The total FLT efficiency was 98% for neutral current events and 85% for charged current events above Q2 of 10 GeV2. The introduction of the isolated electron trigger increases the CFLT beam gas rejection by a factor of two
