摘　　要：　详细讨论了强流射频四极加速器高频输入耦合环的一些基本问题,完成了高频输入耦合环的初步物理设计.利用二维程序Superfish的一些结果,确定了耦合环的大小,计算了耦合环的功耗,并对构成耦合环导线的粗细进行了估算。该耦合环的物理设计可作为耦合环试验的基础,同时,也可作为三维程序HFSS模拟计算的起点。A detailed discussion was carried out on some basic problems related with the coupling loop of radio frequency quadrupole with intense beams. A preliminary design of the coupling loop was given. By making use of some results got from the simulations on radio frequency quadrupole with two-dimension code Superfish, the size of the coupling loop and power dissipation on the loop were calculated. These results are helpful in determining the size of the coupling loop in experiments.
