Abstract
A variety of ISOL targets for generation of radioactive ion beams have been successfully developed at the Holifield Radioactive Ion Beam Facility. Short-lived ion species generated from fast release targets made up of fibrous materials such as HfO2, and coated low-density carbon foam target matrices such as UC2/RVCF targets have been applied in important research programs of nuclear physics and astrophysics. In this paper, computer modeling of the HRIBF targets are introduced, and the computation results are coincident with the experimental measurements. These studies provide a cost effective method to understand beam power deposition as well as temperature distribution in ISOL target presently utilized at the HRIBF and predict the capability of high power ISOL target designs and the temperature profiles with other target materials and geometries for the future facility upgrade.
