摘要

摘要: 废束站束窗是废束站的重要部件。利用束流的束斑尺寸及功率确定束窗能量的高斯分布方式；通过蒙特卡罗方法计算束窗的沉积能量。利用ANSYS稳态分析确定束窗的材料、截面形状和厚度。通过计算比较束窗在不同材料、截面形状和厚度条件下的温度、应力和变形，得出合适的束窗材料、截面形状和厚度，从而确定束窗的最终结构。最后利用瞬态方法模拟束窗调束时的温度分布情况。

Abstract: Dump beam window is an important part of the dump. The Gaussian distribution of energy was decided by the beam size and power. The energy deposition was calculated by the Monte Carlo method. The thermal steady-state analysis of ANSYS was applied to decide the material, section shape and thickness of the dump beam window. The temperature, stress and deformation with different materials, section shapes and thickness were analyzed and compared to get the suitable material, section shape and thickness for the dump beam window. The final structure of the dump beam window was decided accordingly and the temperature of the window was simulated by the transient analysis of ANSYS.
