초록
High-frequency electron accelerators are widely used in the various radiation equipment such as container inspection device, non-destructive inspection system and radiation therapy. The RF characteristics of S-band (2856 MHz) side-coupled structures for accelerator cavity were measured by using E-antenna (in refection), part of the half cell cavity was found to be out of error bound from resonance frequency, and thus was re-processed. When the error bound of the frequency is within 2 MHz, it can be reduced by using external tuning device. But if the error bound is bigger than 10 MHz, external tuning device cannot be used. In this study, Based on the result of accelerator cavity simulation and the precise machining, accelerating cell part and side-coupling cell were reprocessed to produce accelerator cavity frequency that is fit to purpose.
Abstract
