正在为中国加速器驱动亚临界系统 (C-ADS) 直线加速器的注入器方案 II 设计 162.5 MHz、2.1 MeV 射频四极杆 (RFQ) 结构。 RFQ 将根据需要以连续波 (CW) 模式运行。对于CW常导电机来说，热管理将是最重要的问题之一，因为温度波动可能导致腔体变形并导致谐振频移。因此，需要进行详细的多物理场分析，以确保腔体能够稳定地工作在所需的功率水平。多物理场分析过程包括射频电磁分析、热分析、力学分析，这个过程会迭代多个周期，直到找到满意的解。作为广泛接受的措施之一，冷却水系统用于频率微调，因此也研究了冷却水系统在不同条件下的调谐能力。结果表明，采用冷却水系统，温升和频移都可以控制在可接受的水平。
A 162.5 MHz, 2.1 MeV radio frequency quadruples (RFQ) structure is being designed for the Injector Scheme II of the China Accelerator Driven Sub-critical System (C-ADS) linac. The RFQ will operate in continuous wave (CW) mode as required. For the CW normal conducting machine, the heat management will be one of the most important issues, since the temperature fluctuation may cause cavity deformation and lead to the resonant frequency shift. Therefore a detailed multi-physics analysis is necessary to ensure that the cavity can stably work at the required power level. The multi-physics analysis process includes RF electromagnetic analysis, thermal analysis, mechanical analysis, and this process will be iterated for several cycles until a satisfactory solution can be found. As one of the widely accepted measures, the cooling water system is used for frequency fine tunning, so the tunning capability of the cooling water system is also studied under different conditions. The results indicate that with the cooling water system, both the temperature rise and the frequency shift can be controlled at an acceptable level.
