小型、便携工业探伤加速器具有广泛的应用市场,可应用于核工业、航空航天工程,以及地质、电力等部门。便携式工业探伤加速器要求整机轻巧,可以现场、在线、实时检测。X-波段加速结构具有尺寸小、分流阻抗高、建场时间短、加速梯度高及电场击穿阈值高的特性,可以满足小型工业探伤机的要求。本文描述了一种供便携式工业探伤加速器使用的X波段轴耦合驻波加速管物理设计。根据粒子动力学计算结果和2-D电磁场计算结果,给出该加速管的性能参数。π/2模式轴耦合驻波加速管具有群速度最大,频率稳定性好,便于微波测量与调整;结构轴对称,易于加工、焊接及冷却;且加速管外径小,可以减少屏蔽体的重量,因此选用该型加速管。加
Small, portable industrial inspection accelerator has a wide range of applications, can be applied to the nuclear industry, aerospace engineering, and geological, electric power and other departments. Portable industrial detector accelerator requires lightweight machine, you can live, online, real-time detection. The X-band accelerated structure has the characteristics of small size, high shunt impedance, short construction time, high acceleration gradient and high electric field breakdown threshold, which can meet the requirements of small industrial detector. This article describes a physical design of an X-band axis coupled VSWR for portable industrial inspection accelerators. The performance parameters of the accelerating tube are given based on the results of particle dynamics calculation and 2-D electromagnetic field calculation. The π / 2 mode axis coupled standing wave accelerating tube has the highest group velocity, good frequency stability, and is convenient for microwave measurement and adjustment. The structure axis is symmetrical, which is easy to process, weld and cool. The outer diameter of the accelerating tube is small, which can reduce the weight of the shielding body , So choose this type of accelerating tube. plus
