在质子速度为0.1～0.5c范围,美国Los Alamos实验室提出一种新的加速结构CCDTL。我们利用铝模及铜模,对CCDTL结构进行研究。CCTDL模型腔列由四个加速单元及三个耦合单元组成。采用单漂移管CCDTL结构。对CCDTL的模型进行了调谐及测试,获取了初步的实验数据,如谐振频率、色散曲线、耦合系数、场分布等 In the proton velocity of 0.1 ~ 0.5c range, the United States Los Alamos laboratory proposed a new accelerating structure CCDTL. We use aluminum molds and copper molds to study CCDTL structures. The CCTDL model cavity column consists of four acceleration units and three coupling units. Single drift tube CCDTL structure. The CCDTL model was tuned and tested, and preliminary experimental data were acquired, such as resonant frequency, dispersion curve, coupling coefficient, field distribution, etc.
