Abstract：
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 Xband 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 TM110 mode in a X-band 30cm structure are obtained with bead pull measurements.
