本文介绍了一种有效的冷却设计方法，以消除高平均功率工作的射频四极杆谐振腔中射频引起的频移。射频功率输入腔内后，由于腔内温度的变化，频率可能发生移位。然而，在设计阶段，可以通过优化冷却通道位置和叶片和壁面的水流速率来减小rf引起的频移。冷却水的温度对射频频移没有影响。通过对腔体的电磁、热学和力学耦合分析实现了该方法，并在CW/ 100kw FRIB RFQ的冷却设计中进行了验证。设计总流量为18.2 kg/s，射频频移为-0.4 kHz。在运行过程中，可以进一步在容差范围内调节流量，以尽可能减少射频引起的频移。除RFQ型腔外，该方法也适用于具有类似结构特性的其他室温加速器的冷却设计。
This paper describes an effective cooling-design approach to the elimination of the RF-induced frequency-shift in the resonant cavity of the Radio Frequency Quadrupole with the high average-power operation. After the RF power is fed into the cavity, the frequency may shift due to the temperature change in the cavity. However, the RF-induced frequency shift can be diminished by the optimization of the cooling passage location and the water flow rate in the vane and wall during the design phase. The temperature of the cooling water has no effect on the RF-induced frequency shift. This approach is implemented by the coupled electromagnetic, thermal and mechanical analyses of the cavity, and has been performed on the cooling design of the CW/100 kW FRIB RFQ. The total designed flow rate is 18.2 kg/s and the RF-induced frequency shift is -0.4 kHz. During operation, the flow rate can be further adjusted within tolerance to diminish the RF-induced frequency shift as much as possible. Besides the RFQ cavity, this method is applicable to the cooling design of other room-temperature accelerators with similar structural characteristics.
