在不久的将来，一个世界性的挑战将是找到一种方法，在不依赖研究反应堆的情况下生产足够数量的放射性同位素。这项关于靶的创新工作的动机在于使用中子转换器靶以加速器为基础生产放射性同位素，如通过绝热共振交叉概念进行嬗变。利用计算流体力学程序CFX对多通道氦冷器件进行了热分析。在模拟过程中考虑了不同的边界条件，并研究了许多重要的参数，如最大允许固体目标温度以及均匀的入口速度和出口压力在通道中的变化。结果证实，冷却配置工作良好，因此，这样的固体目标可以安全地操作，可以考虑作为原型目标。
A worldwide challenge in the near future will be to find a way of producing radioisotopes in sufficient quantity without relying on research reactors. The motivation for this innovative work on targets lies in the accelerator-based production of radioisotopes using a neutron converter target as in the transmutation by adiabatic resonance crossing concept. Thermal analysis of a multi-channel helium cooled device is performed with the computational fluid dynamics code CFX. Different boundary conditions are taken into account in the simulation process and many important parameters such as maximum allowable solid target temperature as well as uniform inlet velocity and outlet pressure changes in the channels are investigated. The results confirm that the cooling configuration works well; hence such a solid target could be operated safely and may be considered for a prototype target.
