摘　　要：介绍了一种T型桥全通域网络的频率特性和计算结果。将这种具有频率带通特性的全通域网络运用于同步加速器高频腔体,就形成了一种新型同步加速器无调谐高频腔体。这种新型高频腔体具有比同步加速器常规高频腔体相对优越的性能。A bridged-T type all-pass network is introduced in this paper with its calculation results and frequency responses. With the utilization of this all-pass network, a new type of tuning-free RF acceleration cavity is obtained for synchrotron. The merits of better performance of such a tuning-free RF cavity than the conventional tuning RF cavity make it very attractive in synchrotron application. The possibility of using such a tuning-free RF cavity in HIRFL-CSR (Cooler Storage Ring) project at Lanzhou is also discussed. By applying multiple-frequency flat-topping acceleration technique, the capture efficiency of the radioactive ion beam of large emittance at CSR will be enhanced.
