一种简易的电荷堆积排除器

A simple charge pile-up rejector

本文介绍一种应用于离子束分析实验的电荷堆积排除器,它可以有效地消除入射束流在绝缘体样品上产生的电荷堆积。本方法结构简单、易于制作。文中给出了采用这种电荷堆积排除器测得的瓷碟上白釉的背散射能谱。

A simple charge pile-up rejector is described. It can be used in ion beam analysis experiments to neutralize the ion charge pile-up on the isolation target. A typical Rutherford backscattering spectrum from white porcelain glaze on a dish is presented.
