Abstract

The jet chamber of the OPAL experiment at the e+e-collider LEP is designed to measure the momentum of charged particles as well as the specific energy loss in the chamber gas. In this paper, the calibration procedure for the energy loss measurement is described in detail. A resolution of 3–4% has been achieved allowing identification of particles with momenta up to 20 GeV/c in dense particle environments typical for events from Z0 decays.
