切伦科夫辐射是一种方向性极好的辐射,其辐射能量发射方向严格地与带电粒子的运动方向相关,辐射光携带了带电粒子的方向信息,利用这种特性可以进行电子束发散角及其分布的测量。在基于切伦科夫辐射原理的基础上,考虑电子与物质作用时的多重库仑散射、电离等效应,进行了电子束发散角测量的蒙特卡罗数值模拟程序的建模工作,并完成了理想电子束及具有发散角分布的电子束的测量技术模拟工作。大量模拟结果显示,这种测量方法是可行的,具有对电子束发散角分布进行直接测量的能力,并且其测量系统结构简单。
Cerenkov radiation is an extremely directional radiation whose radiation energy emission direction is strictly related to the movement direction of the charged particles and the radiation light carries the direction information of the charged particles. With this feature, the electron beam divergence angle And its distribution measurement. Based on the Cerenkov radiation principle, the Monte Carlo numerical simulation program of electron beam divergence measurement was modeled considering the multiple Coulomb scattering and ionization effects under the action of electrons and species, and the ideal E-beam and electron beam with divergent angle distribution measurement technology simulation work. A large number of simulation results show that this measurement method is feasible, with the ability to directly measure the spread of the electron beam divergence angle, and the measuring system is simple in structure.
