摘要
电子束束参数是衡量各种加速器产生的电子束品质的重要参数,其测量技术的研究及测量工作是极其重要的一个方面。由于加速器研制水平的提高,尤其在调试阶段对束参数的测量要求也变得更高,体现在高的时间分辨能力和更好的空间分辨率、数据更高的动态范围及更加直观的可视性。针对束参数中最基本的参数如束斑测量、发射度测量、能量测量等技术,利用已研制的高性能设备,针对强流脉冲电子束的特点,基于多种主要原理研制了比较完整的、时间分辨能力高达2 ns、高灵敏度、高动态数据范围的电子束束参数光学测量及诊断系统,并编制了一套处理程序,达到了现场实时的数据处理水平,具有直观诊断的特点,为解决调试工作中诸多的问题提供翔实而准确的数据,成功地应用于多个加速器的调试。
Abstract
The beam parameters measurement is the most important work for the study of linear induction accelerator(LIA). The beam parameters are important to evaluate the character of the beam. The demands of beam parameters measurement are improving while the development of accelerator is improving. The measurement difficulty features higher time-resolved ability, higher spatial resolution, larger dynamic range and higher intuitionistic view data. The measurement technology of beam spot, beam emittance, beam energy has been developed for the past several years. Some high performance equipments such as high speed framing camera are developed recently. Under this condition, the relative integrated optical measurement and diagnostic system for the beam parameters is developed based on several principles. The system features time-resolved ability of up to 2 ns, high sensitivity and large dynamic range. The processing program is compiled for the data process and the local real-time process is reached. The measurement and diagnostic system has provided full and accurate data for the debug work and has been put into applications.
