GEANT from a user view-point

GEANT program package (FORTRAN, the BESM-6 computer) designated for computerized simulation of experiments on elementary particle physics is described. Algorithms realized in programs forming a part of GEANT enable the user to solve the following problems: to perform processes of elementary particle interaction by Monte-Carlo method, to determine particle tracks in space with regard to particle interaction with a substance, to determine coordinates of track traverse points with detectors of experimental facility, to transform transverse point coordinates into detector readings. The described program package is realized in the form of RAM-file in RATSNU-4 standard. GEANT program package is used for simulation of experiments at the ITEP 3 meter spectrometer
