The ALICE CPV Detector

Abstract

The Charged-Particle Veto (CPV) detector of ALICE at the LHC is presented. Physics motivation for the detector, its construction and operation in physics runs are shortly discussed. Readout electronics and data taking conditions are described. Special attention is focused on CPV automation via the detector control system. Different states of the detector and protection algorithms implemented into the control system are described.
