[en] In Nuclear Astrophysics (NA) experiments low fusion or capture cross-section make the measurements with appreciable accuracy difficult. In order to improve the statistical accuracy in a reasonable time of the beam time, a high current is desirable. The purpose of this simulation will be to develop an idea about the amount of heating generated in the target, its temperature profile and how the temperature can be controlled by heat dissipation and the different factors on which it depends. The simulation will mostly be based on the physical concepts and more realistic aspects that will lead to the design of a cooling setup which will be developed based on the present basic study
