摘要
为 2 0 Me V直线感应加速器建造的 2 Me V注入器经过一年多实验调试 ,束流技术指标已达到能量 2 Me V、束流 3 k A、亮度≥ 1 0 8A/ ( m· rad) 2 。建立了二维数字模型 ,并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。
The beam current, energy and brightness of 2MeV injector for 20MeV LIA have been up to 3kA, 2MeV and 10-8A/(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.
