摘　　要：Peking University is developing a 1.3 GHz superconducting accelerating section highpower THz free- electron laser for the China Academy of Engineering Physics （CAEP）. A compact fast/slow tuner has been developed by the Institute of High Energy Physics （IHEP） for the accelerating section to control Lorentz detuning, compensate for beam loading effect, microphonics and liquid helium pressure fluctuations. The tuner design, warm test and cold test of the first prototype are presented, which has a guiding significance for the manufazture of the formal tuner and cryomodule assembly.Peking University is developing a 1.3 GHz superconducting accelerating section highpower THz free- electron laser for the China Academy of Engineering Physics （CAEP）.
