摘　　要：海关大型货物在线检测用加速器采用4MW速调管作为微波功率源,保证加速管入口功率可达35MW、工作频率为2856MHz;以行波方式加速电子,聚束器俘获效率大于80%;加速管全长约220cm;电子能量设置9、6MeV两档,对应的额定脉冲束流强度理论设计值分别为170和300mA。本文给出了纵向粒子动力学。An accelerating tube is described in this thesis. It is a part of an accelerator used for inspection of vehicle cargoes in rail cars, trucks, shipping containers, or airplanes in customs. A klystron with power of 4 MW and frequency of 2 856 MHz will be applied to supply microwave power. The electrons can be accelerated by a travelling wave in the accelerating tube about 220 cm long, with a buncher whose capture efficiency is more than 80 %. Energy of electrons after travelling through the tube can reach 9 MeV (pulse current intensity 170 mA)or 6 MeV (pulse current intensity 300 mA). Physical design of the accelerating tube, including the calculations of longitudinal particle dynamics, structure parameter and working character is carried out.
