为我国2011年启动的ADS项目设计了一台四叶片涡轮加速器。作为C-ADS直线加速器的两个前端之一，该加速器工作在162.5MHz的频率，将质子束从35 keV加速到2.1MeV。由于CW（连续波）操作模式，采用了1.2的小Kilpatric因子。同时采用π模棒来减小偶极模对四极模的影响，并通过调节冷却水的温度来实现腔的调谐。本文将介绍束流动力学设计、射频腔设计和热分析。文中还介绍了该谐振腔的一些制作试验。
A four-vane RFQ accelerator has been designed for the ADS project which has been launched in China since 2011. As one of the two front ends of C-ADS LINAC, the RFQ works at a frequency of 162.5MHz, accelerating the proton beam from 35keV to 2.1MeV. Due to the CW (continuous wave) operation mode, a small Kilpatric factor of 1.2 was adopted. At the same time, Pi-mode rods are employed to reduce the effect of dipole mode on quadrupole mode, and cavity tuning will be implemented by temperature adjustment of cooling water. Beam dynamics design, RF cavity design and thermal analysis all will be presented in the paper. Some fabrication test of the RFQ cavity will be described, too.
