介绍用来产生放射性核束的厚靶的物理设计过程，提出对靶材料特性和温度条件的严格要求，列举了几种候选靶材，设计了１个石墨靶衬并合理安排靶的水冷散热结构，计算了厚靶的三维温度分布情况。计算结果表明：此厚靶完全能够承受最高达１４ｋＷ的质子束入射束流功率，靶的温度可以根据不同要求控制在１３００—２０００℃。
This paper introduces the physical design process of thick targets for generating radioactive nuclear beam, puts forward the strict requirements of target material properties and temperature conditions, lists several candidate targets, designs a graphite target lining and arranges the target water cooling structure , Calculated the thickness of the target three-dimensional temperature distribution. The calculated results show that this thick target can fully withstand the beam power of proton beam up to 14kW, and the target temperature can be controlled at 1300-2000 ℃ according to different requirements.
