Synchrotron-based or FEL-based light source have been proven to be an essential tool in many areas of research, including materials science, chemistry, biophysics and biochemistry, medicine, and physics. But its applications set stringent requirements on the desired performance of the electron gun. Electron beam brightness is the deterministic factor in the performance of light source. The successful completion of this project should allow development of a novel electron beam source to meet such demands.
This project seeks to develop a novel electron beam source using dual harmonic mode superposition to increase acceleration gradient and improve output beam quality without increasing the RF breakdown probability. One of the possible direct application is to provide a high-quality electron beam for positron production and detector calibration in support of goals of Wright Lab. Furthermore, one can foresee wide commercial and industrial interest in this concept of high quality electron beam source, for use in accelerator R&D, medical diagnostics and therapy.
