摘要
强脉冲离子束在靶上的横截面能量密度分布和束流焦点位置是束流分析和辐照效应研究中重要的技术参数.利用红外成像诊断技术,可以以较高的空间分辨率和能量密度分辨率对束流的横截面分布进行测量,并可以实现对束流焦点的测量和束流传输特性的分析.通过该实验,可以使学生掌握强脉冲加速器诊断的基本技能,加深对加速器原理及脉冲束流分布和传输特性的认识.
The cross sectional energy density distribution of intense pulsed ion beam is of great significance to beam characterization and application.Using infrared imaging diagnostic techniques,the cross sectional distribution analysis of IPIB is achieved with high spatial and energy density resolution.With this method the measurement of the beam focus and the beam transmission characteristics analysis are carried out.This diagnostics can be used to make further understanding of the working principles of intense pulsed accelerator and master the basic skills in carrying out diagnostics to powerful pulsed beams.
