介绍了一种用于测试X波段加速管中高阶模电场分布的笼子式微扰体的研制与标定. 该微型扰动体通过专门设计加工的固定装置，在尼龙线表面平行沉积溅射数根金属丝膜制成. 利用一标准圆柱腔，对笼子式扰动体的扰动因子进行了定标，证实金属丝笼子式扰动体与同外形尺寸的金属圆筒相比，具有高分辨率、高灵敏度的优点. 采用笼子式扰动体测试了一根长30cm的X波段加速管中TM110模的纵向电场分布.

A metallic cage made by sputtering silver film onto a thin nylon thread through a specially designed fixture is used as perturbing object to measure the higher modes in a Xband accelerating structure. The fabrication and calibration of the cage are described in this paper. It is found that this type of perturbation object has the advantages of high sensitivity and high resolution. Using the cage as bead, the longitudinal electric fields of TM110 mode in a Xband 30cm structure are obtained with bead pull measurements.
