Implementation of Main Waveguide Cavities of Electron Linear Accelerator Using Integrated and Separable Methods and Comparing Their Performance

There are many methods for fabricating electron linear accelerator cavities. In the present research two methods were chosen: first, separable parts (separate ring and disks) and second, parallel disks and cylinder (integrated). The resonance frequencies of cavities and the quality factor of each frequency are two important parameters in their performance. The comparison of measured parameters of the cavities made with two methods, firstly by the network analyzer machine and secondly using the HFSS simulator. The results of both the practical measurements and the simulation of the two structures indicated that the integrated method is better for implementing cavities.
