Abstract
The resonant frequency stability of the radio frequency quadrupole (RFQ) is an important concern during commissioning. The power dissipated on the RFQ internal surface will heat the cavity and lead to a temperature rise and a structural deformation, especially in the continuous wave (CW) RFQs, which will cause the resonant frequency shifts. It is important to simulate the temperature rise, the deformation and the frequency shift of the RFQ cavity. The cooling water takes away the power to maintain the frequency stability. Meanwhile, the RFQ resonant frequency can be tuned by adjusting the water temperature. In this paper, a detailed three-dimensional multi-physics analysis of the Low Energy Accelerator Facility (LEAF) RFQ will be presented and a commissioning frequency tuning strategy will be studied.
