Abstract :
Design of the buncher cavity for Cornell/JLab ERL project is presented. This is a reentrant spherical copper cavity at a frequency of 1300 MHz. It will be installed between a 500 keV electron gun and superconducting accelerating sections in the injector part of ERL. The cavity has Q of 20,000 and a shunt impedance of 2.1 MOhm. For a design cavity voltage of 200 kV, power dissipated in cavity is as much as 9.6 kW. The cavity has a coaxial loop coupler and will be driven by a 17.5 kW klystron. The estimates of cavity influence on beam dynamics are also discussed.
