Abstract

The algorithm and results of calculating the integral and differential energy spectra of a pulsed electron beam (350–500 keV, 80 ns), generated by direct-action accelerators, are presented. The electron spectrum was calculated using the oscillograms of the accelerating voltage, electron current, total current of the diode, and the one-dimensional Child–Langmuir (1D CL) ratio. It was found that the discrepancy in the integrated electron beam energy spectrum, when measured using the total current in the diode and using the electron beam current, did not exceed 15% for 80%–95% of the electrons generated in a diode with graphite, carbon fabric, and multipoint cathodes. When calculating the electron spectrum using the 1D CL, the error was much higher.

用电流和电压示波图测定脉冲电子束能谱

本文介绍了直接作用加速器产生的脉冲电子束(350 ~ 500 keV, 80 ns)的积分能谱和微分能谱的计算方法和结果。利用加速电压、电子电流、二极管总电流和一维Child-Langmuir (1D CL)比的示波图计算了电子能谱。研究发现，在石墨、碳织物和多点阴极二极管中产生的80%-95%的电子中，当使用二极管中的总电流和使用电子束电流测量时，集成电子束能谱的差异不超过15%。当使用1D CL计算电子能谱时，误差要高得多。

期刊介绍： Laser and Particle Beams is an international journal which deals with basic physics issues of intense laser and particle beams, and the interaction of these beams with matter. Research on pulse power technology associated with beam generation is also of strong interest. Subjects covered include the physics of high energy densities; non-LTE phenomena; hot dense matter and related atomic, plasma and hydrodynamic physics and astrophysics; intense sources of coherent radiation; high current particle accelerators; beam-wave interaction; and pulsed power technology.
