【摘要】 通过电子枪的优化设计、测量电路的设计以及测量方法的选择,成功设计了一种加速器真空室常用材料二次电子产额的测量装置。用此系统测量了原电子能量在0-3keV时不锈钢、无氧铜、TiN膜等材料的二次电子产额,某些相同材料的测量结果与国内外资料相近似。实验结果可为新一代加速器真空室的设计以参考,对于国内在此领域的深入研究有一定的借鉴意义。更多还原

【Abstract】 A system for measuring secondary electron yield(SEY)of some accelerator vacuum chamber construction material had been set up successfully by the optimization design of electron gun、design of measurement circuit and selection of measurement method.The SEY of stainless steal(SS)、OFHC、SS coated with TiN thin film had been measured in the system with the primary electron energy of 0-3keV,and some of the measurement result accord with the reported data. These measurement result can be as reference to design of next generation accelerator vacuum chamber and further research in this field.更多还原
