Abstract
The effect of the powerful ion beams (PIB) with a power density of APP 1STH 10**9 W/cm**2 on the absorber causes heating of the latter. To describe the temperature field of the absorber, it is essential to know the heat source formed as a result of dissipation of the energy of the ion beam. The construction of the function of the heat source (heat generation function) which takes into account the fine mechanisms of interaction between the incident ion and the absorber is quite cumbersome even within the framework of simulation. To carry out thermal calculation, it is sufficient to have a simple algorithm of construction of the heat source reflecting the main relationships of distribution of absorbed energy which would be universal in relation to the variations of the parameters of the beam and the absorber. In this work, the authors propose approximation of the heat source in the absorber constructed on the basis of experimental results. Comparison of the results calculated from the equations derived with the tabulated data show that the error of approximation is maximum in the vicinity x approximately c//1 and does not exceed 6-8% for Z//1 less than 35 and E//0 APP GRTH 0. 5 MeV/nucleon.
