摘要：

A resonator for a flat-top acceleration system in the RIKEN AVF cyclotron is designed to improve the extraction efficiency and the energy spread of the beam, The fundamental-frequency range is from 12 to 23 MHz and its maximum accelerating voltage is 50 kV. In order to generate the flat-top accelerating voltage on the dee, an additional resonator is required. which is coupled to the main resonator with a coupling capacitor. The flat-top accelerating voltage is obtained by superimposition of the fundamental-frequency and the fifth-harmonic-frequency voltages. We performed a cold model test of the flat-top system using a full-scale model coupled to the main resonator. It was found that the fifth-harmonic mode was realized below 68.71 MHz, but not in the whole required range.
