Abstract

The Advanced Continuous-wave Electron injector aims to provide accelerator-based light sources with a high repetition rate and high average current electron beam. The injector consists of a DC thermionic gun generating a continuous electron beam, after which a radio-frequency (rf) cavity operating in dual mode at 1.5 and 3 GHz deflects the beam onto a knife-edge, creating a pulsed beam. A final rf cavity, also operating at 1.5 and 3 GHz, compresses the electron bunches for injection into a booster linac. The DC thermionic gun is fully operational and this paper presents the first results, demonstrating a continuous beam with a transverse emittance of 49±2 nm rad at 9.6 mA.
