Design of a 1.3 GHz CW Room Temperature Buncher for the PAPS Project | |
|
||
| A 1.3 GHz CW room temperature buncher is located between the DC gun and the superconducting accelerator modules in the PAPS project. A brief beam dynamic study of the buncher system will be presented in this paper. According to the beam dynamic study, the effective cavity voltage should be more than 120 kV. The designed cavity has a unload Q of 23000 and a shunt impedance of 5.3 MΩ. 3-D electromagnetic simulation codes CST MWS and HFSS are used to optimize the inner dimensions of the buncher cavity. The multi-physics analysis is carried out to determine the cooling scheme and the mechanical sizes of the metal body. The RF coupler design and HOM analysis will also be presented in this paper. | ||
