Abstract

Abstract

Tuner system is the indispensable part of ADS high current proton superconducting linac.It influences the working frequency of superconducting cavity of particle accelerator.To completely understand the working situation of the tuner system and analyse the problems, experiments were fully conducted.The lever structure and scissor structure of tuner were analyzed first, then the electric field simulations of the HWR superconducting cavity under different conditions were performed, and it was concluded that the force of tuning and tuning displacement meet the frequency tuning requirements of HWR cavity.Finally, the linearity and return difference of the tuner and linear unit in thermostats CM1, CM2, and CM3 were tested automatically and manually.The tuner of CM1 basically meets the need of slow tuning.In the test result of CM2 return of 1200 steps occurred, mainly due to the linear unit.The tuner of CM3 has a large return difference and a little worse linearity that need further improvement.
