中文摘要：

研制了大功率宽带快速扫频射频系统,其用于中国散裂中子源（CSNS）快循环同步加速器（RCS）中,主要包括铁氧体加载谐振腔、射频功率源、偏流源和低电平控制系统。射频系统工作重复频率为25Hz,扫频范围为1.022～2.444MHz,单个腔体（双加速间隙）可提供最大30kV加速电压。两级的调谐控制能解决快速扫频过程中的系统失谐问题,采用束流前馈、直接反馈等多种技术手段可对束流负载效应进行补偿。

英文摘要：

A high power,broadband and rapid frequency sweeping RF system was developed to satisfy the demand of China Spallation Neutron Source（CSNS）rapid cycling synchrotron（RCS）.The RF system mainly includes a ferrite loaded resonant cavity,a RF power source,a bias supply and a low level RF system.The repetition frequency is 25 Hz and the sweeping frequency range is 1.022-2.444 MHz.One cavity with two gaps can provide a maximum accelerating voltage of 30 kV.The tuning control of two stages can successfully solve the detuning problem during rapid frequency sweeping.The beam feed-forward and direct feedback can compensate the heavy beam loading effect.
