Abstract

Locally inclined targets are developed to produce medical radioisotopes which can be used for high-intensity proton beam irradiation. The results of a numerical analysis of thermal processes in locally inclined targets made of pressed molybdenum powder with a niobium target holder for the Nirta Solid Compact Model TS06 target module are presented. Computations were carried out using the Fluid Flow (Fluent) engineering package of the ANSYS Workbench 18.2 software platform for variants of targets with linear and axially symmetric grooves in the proton irradiation zone. It has been shown that using various models of locally inclined targets with a cooling area increased by 2.37 times, it is possible to increase the irradiation current by 1.34–1.46 times compared to a standard flat target. An analysis of the distribution of heat flows and temperatures in the targets was also carried out.

利用 Nirta 固体紧凑型靶模块对局部倾斜靶的冷却过程进行数值建模

摘要开发局部倾斜靶是为了生产可用于高强度质子束辐照的医用放射性同位素。本文介绍了对 Nirta Solid Compact Model TS06 靶件模块的局部倾斜靶件中的热过程进行数值分析的结果，该靶件由带铌靶架的压制钼粉制成。计算是使用 ANSYS Workbench 18.2 软件平台的流体流动（Fluent）工程软件包进行的，适用于质子辐照区内带有线性和轴对称凹槽的各种靶件。结果表明，使用冷却面积增加 2.37 倍的各种局部倾斜靶模型，可以使辐照电流比标准平面靶增加 1.34-1.46 倍。此外，还对靶中的热流和温度分布进行了分析。
