SOFTWARE IMPLEMENTATION OF TARGET SYSTEM IN CLAS DETECTOR AND CALCULATION OF CORRECTIONS DUE TO ENERGY LOSSES BY CHARGED PARTICLES IN THE TARGET MATERIAL

摘要

A technique of the software implementation for the simulated target system of the CLAS detector is described. It reproduces exactly the realistic pattern of the target-detector complex. This allows one to calculate the corrections to the measured momenta of charged particles caused by the energy (momentum) losses in the target material. By the analysis of the missing mass distribution it is shown that the obtained corrections reproduce well the measured proton momentum values in the quasi-elastic d(e,e'p) scattering.
