摘要：
This paper deals with the design of high-Q0 TE resonators for high-efficiency rf pulse compression. The aim of our study was the development of a storage resonator to be used for an energy doubler (similar to the one used on the Stanford linac energy doubler (SLED) to increase the beam energy of the Stanford linac to 53 GeV), but to be used for a linac having a quite long filling time of 1.2 ωs. For this reason the storage resonator must be designed for an unloaded Q0 of roughly 105. By using our OSCAR2D computer code (which computes the resonant frequency, Q0 and geometry factor for any reasonable TE or TM monopolar mode of cylindrically symmetric rf cavities) we found an optimum resonator geometry. On this geometry we get the benefit of a Q0 about 10% higher than that of an ideal cylindrical cavity together with the splitting of TE0mn-like and TM1mn-like modes which in a cylindrical cavity are coalescent. © 1990.
