电子直线加速器要求有一个束流品质优良的电子源。在常规的脉冲电子枪,如二极管式的电子枪提供的电子束流时间波形,它的上升时间(简称前沿)和下降时间(简称后沿)都大于1微秒,难于满足物理试验对直线加速器的能散度要求.为了改善其波形,减少能散度,减轻后面环节的束流负载,我们设计了一台结构紧凑的切割器.实验证明,它可对能量 Electron linac requires an electron beam with good beam quality. In the conventional pulse electron gun, such as the diode-type electron gun provides the time-waveform of the electron beam, its rise time (referred to as the front) and fall time (referred to as the trailing edge) are greater than 1 microsecond, difficult to meet the physical test of linear accelerator Divergence requirements In order to improve its waveform, reduce the energy dissipation and reduce the beam load in the later part of the cycle, we designed a compact cutter that has been experimentally demonstrated that it can be used for energy
