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

摘要

This paper presents an extensive numerical study of heating of thin solid carbon foils by $1.4ext{ }ext{ }mathrm{MeV}/mathrm{u}$ uranium ion beams to explore the possibility of using such a target as a charge stripper at the proposed new Gesellschaft f"ur 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 f"ur Schwerionenforschung high energy heavy--ion linac, in particular, at FAIR design beam intensities.
