Abstract

In this paper, we show the influence of the chemical structure of four different conformers on the secondary electron emission and backscattering of an electron beam from a gel of methacrylic acid. The conformers have different permanent dipole moments, which determines the cross sections for elastic collisions with electrons. The cross sections are used in Monte Carlo simulations of an electron beam, which enters the gel of methacrylic acid. The secondary electron yield and the backscattering coefficient are computed as a function of the beam energy.

摘要

在本文中，我们展示了四种不同构象的化学结构对甲基丙烯酸凝胶中电子束的二次电子发射和背散射的影响。这些构象具有不同的永久偶极矩，这决定了与电子发生弹性碰撞的截面。这些截面被用于模拟电子束进入甲基丙烯酸凝胶的蒙特卡罗模拟中。二次电子产额和背散射系数作为束能的函数进行计算。
