The new injector SSC-LINAC is under design and con-struction to improve the efficiency and intensity of beams for the Separated-Sector Cyclotron (SSC). This will be accomplished with a normal conducting radio-frequency quadrupole (RFQ) accelerator. To match with the SSC, the RFQ must be operated on Continuous Wave (CW) mode with a frequency of 53.667 MHz. A four-rod structure was adopted for small dimensions of the cavity. While, it was a huge challenge on CW mode. A multi-physics theoretical analysis, including RF, thermal, struc-tural and frequency shift coupling analysis, have been completed in response to the security and stable opera-tion of the RFQ. The experimental measurement of fre-quency shift was also completed, which is consistent with the simulation. In this paper, the results of theoretical analysis and experiment are reported in detail.
