PHYSICAL APPROXIMATION OF THE HEAT DEPOSITION PARAMETERS IN THICK TARGETS BOMBARDED BY MEDIUM-ENERGY PROTONS

The experimental data of the spatial component of heat deposition in b eryllium, carbon, aluminium, iron, copper, bismuth, and lead targets b ombarded by protons in the 0.8-1.2 GeV energy range are analysed. The targets with 0.2 m diameter in the 0.3-0.6 m thick range were used in experiments. The experimental data of the heat deposition density mere obtained by ZOMBE calorimeter. A brief description of the facility co nstruction, measurement blocks, principles of calorimetric data taking , and results of calorimetric experiments are presented.Physical appro ximation of the spatial component parameters are found by using the le ast-squares method. Dependencies of parameters from radiation length, matter density, inelastic interaction length, and other physical param eters are given for the region of proton release energy.
