Περίληψη:
The CPLEAR experiment will measure CP violation parameters in the
neutral kaon system, using a low energy antiproton beam from the Low
Energy Antiproton Ring (LEAR) at CERN. One of its subdetectors, the
Particle Identification Detector (PID), makes a fast separation of pions
and kaons, which is essential for the experiment. This article describes
the design of the PID and its performance during beam tests and during
initial runs at LEAR. A pion rejection efficiency of 99.7% for the
first level trigger (after 60 ns) is found in the relevant momentum
region.
