| TUPB097 | The Study on Microphonics of Low Beta HWR Cavity at IMP | 837 |
|
||
| The superconducting linac of China Accelerator-Driven System Injector II will operate at CW-mode. The mechanical vibrations of the superconducting cavity, also known as microphonics, cause shifts in the resonant frequency of the cavity. The microphonics is the main disturbance source of cavity frequency shifts when the cavity running in CW mode. In order to understand the effects, microphonics measurements were performed on the half-wave superconducting cavities when they were operated in the cryostat. And the experimental modal test was also performed to identify noise source and improve the cavity structure optimization. The measurement method and results will be shown and analyzed in this paper. | ||

| THPB015 | Design of a Medium Beta Half-Wave SC Prototype Cavity at IMP | 1097 |
|
||
| A superconducting half-wave resonator has been designed with frequency of 325 MHz and beta of 0.51. The geometry parameters and the three shapes of inner conductors (racetrack, ring-shape and elliptical-shape) were studied in details to decrease the peak electromagnetic fields to obtain higher accelerating gradients and minimize the dissipated power on the RF walls. To suppress the operation frequency shift caused by the helium pressure fluctuations and maximize the tuner ranges, the frequency shifts and mechanical characters were simulated in the electric and magnetic areas separately. At the end, the helium vessel was also designed to keep stability as possible. The fabrication and test of the prototype will be complete at the beginning of 2016. | ||
