| 摘 要： | ELV-8型加速器的加速管分为变梯度加速管段和等梯度加速管段两部分。阴极为六硼化镧平面阴极。电子束的聚焦采用变梯度场聚焦，使电子束成为层流束。电子枪的平面电极使得阴极发射面前的电场均匀，从而使得加速管的电子光学系统对初始条件不过于敏感，这便于电子枪的替换。

| Abstract: | ELV-8 accelerator use flat lanthanum hexaboride as the cathode .The acceleration tube consists of alternating gradient section and equi-gradient section. Focusing of electron is completed by electrical fields of alternating gradient, which makes electron beam a laminar beam. The flat electrode of the electron gun makes the electrical fields before the gun uniform, so the electron optical characteristic of the accelerating tube is not sensitive to the initial condition and the replacement of electron gun is convenient. |
