摘      要：A 499.8 MHz SOLEIL-type superconducting cavity was simulated and designed for the first time in this *** higher-order mode(HOM)properties of the cavity were *** kinds of coaxial HOM couplers were *** 4 L-type and 4 T-type HOM couplers,the longitudinal impedance and the transverse impedances were suppressed to below 3 kΩand 30 kΩ/m,*** HOM damping requirements of Hefei Advanced Light Facility(HALF)were *** paper conducted an in-depth study on the radio frequency(RF)design,multipacting optimization,and thermal analysis of these coaxial *** results indicated that under operating acceleration voltage,the optimized couplers does not exhibit multiplicating or thermal breakdown *** cavity has the potential to reach a higher acceleration gradient.

主 题 词：HOM coupler superconducting cavity RF system multipacting thermal simulation
