DTL加速器是大型高能加速器装置不可或缺的加速结构。为进一步研究DTL加速器的结构及工作原理,制作了一段模型腔体。该DTL加速结构模型腔的频率为325 MHz,其机械设计的部件主要包括1个圆筒形谐振腔体、13个漂移管组件、11个可动耦合杆组件、4个可动调谐器组件、1个真空组件、1个射频耦合组件以及腔体支架和水冷组件。材料部分除谐振腔体采用碳钢以外,其余所有部分均采用304不锈钢,
The DTL accelerator is an indispensable acceleration structure for large high-energy accelerator devices. In order to further study the structure and working principle of DTL accelerator, a model cavity was made. The DTL acceleration model cavity has a frequency of 325 MHz and its mechanical design consists of a cylindrical resonator, 13 drift tube assemblies, 11 movable coupling bar assemblies, 4 movable tuner assemblies, 1 vacuum assembly, 1 RF coupling assembly and cavity holder and water-cooled assembly. In addition to the material part of the resonant cavity with carbon steel, all other parts are made of 304 stainless steel,
