چکیده
A 325 MHz aluminum prototype of a spatially periodic RF quadrupole focusing linac was developed at the Institute Modern Physics, Chinese Academy Sciences, as promising candidate for front end high-current linac. It consists an alternating series crossbar H-type drift tubes and sections. Owing to its special geometry, cavity fabrication is major hurdle engineering development application. In this paper, we report detailed mechanical design structure describe process, including machining, assembly, inspection. The field distribution measured by bead-pull technique. results show that errors both accelerating fields are within acceptable range. tuning scheme new proposed verified. cold test process presented in detail. provides valuable guidance application structure.
