The COMET experiment (J-PARC E21, Japan) is under development now. Cosmic ray muons can decay in flight or interact with the materials around the matter of the muon-stopping target and produce “fake” signal-like electrons in the detector region. In order to have control over this background, a Cosmic Ray Veto (CRV) system is required for COMET experiment. In accordance with our plan the CRV system consists of 6 panels located along the perimeter and roof of the COMET detector. The panels consist of “strip”palstic scitillator counters with SiPM readout. A special readout and signal processing electronic board is designed to prototype analog and digital pathes. So the performance data and some specific details are presented. The obtained performance is in accordance with specification and satisfy the CRV system requirements.
