2MeV有箔注入器的束流调试
-
摘要: 为20MeV 直线感应加速器建造的2MeV注入器的束流技术指标经过一年多实验调试已达到能量2MeV、束流3kA、亮度≥108A/(m·rad) 2。建立了二维数字模型对注入器的电子发射和束流传输过程进行模拟，模拟结果指导了实验调试，分析了有箔二极管中发生的聚焦作用。Abstract: The beam current, energy and brightness of 2MeV injector for 20MeV LIA have been up to 3kA, 2MeV and 108A/(m-rad)2 respectively after the debugging experiment has been lasting for more than one year. A two-dimensional model was used to simulate the processes of electron emission and beam transportation. The calculated results, compared with the experimental results, were analyzed.
