Over
of data have been collected with the CFLT in the 1993
run. The total CFLT trigger rate has been about 100 Hz with thresholds as
low as 500 MeV. The CFLT was used for every ZEUS first level trigger
employed in physics analysis and was responsible for the majority of the
reduction of rate written to tape (a few Hz). There was zero trigger rate
from noise for trigger tower energy above 500 MeV.
