Three–dimensional simulations of a solid graphite target for high intensity fast extracted uranium beams for the Super–FRS

This paper presents three-dimensional numerical simulations of thermodynamic and hydrodynamic response of it wheel shaped solid graphite production target for the super conducting fragment separator (Super-FRS) that is irradiated with a fast extracted high intensity uranium beam. These fragment separator experiments will be carried out at the future Facility for Antiprotons and Ion Research (FAIR), at Darmstadt. Previously, we reported simulation results that Weir carried out using two-dimensional computer codes which showed that one can use a solid graphite target for the Super-FRS for the highest intensity (5 x 10(11) ions per spill) of the fast extracted uranium beam. Present results, however, have shown that due to three dimensional effects the maximum intensity that can he used with Such a target is 3 x 10(11) ions per spill. A detailed comparison between two-dimensional and three-dimensional results is presented in this paper.
