Three-dimensional thermal simulations of thin solid carbon foils for charge stripping of high current uranium ion beams at a proposed new heavy-ion linac at GSI

Abstract

This paper presents an extensive numerical study of heating of thin solid carbon foils by 1.4 MeV=u uranium ion beams to explore the possibility of using such a target as a charge stripper at the proposed new Gesellschaft für Schwerionenforschung high energy heavy-ion linac. These simulations have been carried out using a sophisticated 3D computer code that accounts for physical phenomena that are important in this problem. A variety of beam and target parameters have been considered. The results suggest that within the considered parameter range, the target will be severely damaged by the beam. Thus, a carbon foil stripper does not seem to be a reliable option for the future Gesellschaft für Schwerionenforschung high energy heavy-ion linac, in particular, at FAIR design beam intensities.

“…Simulations have been carried out by Tahir [22] using a sophisticated 3D computer code that is equipped with ion energy deposition, heat conduction and thermal radiation losses from the target surface. Different phases of the target material are handled by using an advanced multiphase, multicomponent equation of state package [23].…”
