Abstract— The design of an inlet vacuum window, which was developed and manufactured as part of the project of a target station for the production of medical radionuclides, is presented. The calculated data of temperature fields and thermomechanical stresses in the window elements are presented, as well as data on the stress–strain state of the window under the action of the total load (pressure plus uneven heating). Particular attention is paid to the numerical simulation of window cooling by unheated water flows. The “life time” of the window is estimated due to radiation damage to its material. Given the high levels of energy release and induced activity, initiated by protons in the window, as well as its frequent replacement, the AMg6 alloy was selected as the window material.

使用医用放射性核素进行操作的目标站的输入窗口

摘要—介绍了作为医用放射性核素生产目标站项目的一部分而开发和制造的入口真空窗的设计。给出了窗户元件中温度场和热机械应力的计算数据，以及窗户在总载荷（压力加不均匀加热）作用下的应力-应变状态数据。要特别注意由未加热的水流冷却窗户的数值模拟。窗户的“使用寿命”是由于其材料受到辐射损坏而估算的。考虑到窗户中的质子引发的高水平的能量释放和诱导的活动以及频繁更换，AMg6合金被选作窗户材料。
