Abstract

X-band electron linacs are an excellent choice for portable accelerators. In this pager we present an X-band disk-and-washer standing wave structure is studied in this paper for a low energy accelerating tube. The DAW cavities are optimized to obtain the largest shunt impedance and quality for the TM020 mode. A set of differential equations is used to describe the optimizing process. The optimized results of a DAW structure working at 9300 MHz are given using SUPERFISH and MAFIA400. Four radial stem supports are adopted. The modes near to the working frequency are given with and without supports. The electromagnetic field building process was analyzed with T3 of MAFIA400. OFC model DAW cavities are built and the first test results are described
