The Hefei Advanced Light Source(HALS) is a super low emittance storage ring and has a very short beam life time. In order to run the ring stablely, top-up injection will be necessary. The injection system will greatly affect the quality of beam. This article first gives a physics design of the injecting system. Then the injecting system is tracked under different errors. The responses of storage beam and injecting beam are given in the article. 相似文献

采用URMEL-T程序进行了二次发射微波电子枪的腔内电磁计算和特性分析。同时利用URMEL-T得出的腔内轴向电场及自编程序,模拟电子在该高频场作用下的运动。计算表明二次发射微波电子枪确实具有相位选择性,进而探讨了腔形尺寸、射频电场强度对相位选择性和产生二次倍增的有关条件的影响,以及输出电子的能量稳定性。模拟结果表明,这类电子枪(MPG)可得到高电流密度(5303A/cm2)及短脉冲(3.15~10ps)的电子束。 相似文献
