The development of high-current, short-duration pulses of electrons used in injectors of particle accelerators for research and industrial use has been a challenging problem. Current injector methods are complex, cumbersome, expensive and have performance limitations. A high-charge, micro-pulse electron gun offers the potential to improve these conditions in many accelerator applications and in particular for dielectric wakefield accelerators which require high-charge bunches of electrons. This project is to develop an improved accelerator cavity incorporating the High-Charge Micro-Pulse Electron Gun, an outgrowth of prior research. Phase I is aimed at a detailed analysis to establish credible estimates of charge per bunch, radio-frequency power, pulse length, emittance, efficiency, bunch expansion, power handling and other key parameters. Phase II will be aimed at the design, fabrication and testing of a High-Charge Micro-Pulse Electron Gun and a high-gradient single cell radio-frequency cavity section.

Commercial Applications and Other Benefits as described by the awardee: If successful, this electron gun should provide a high-charge, low emittance, picosecond-long electron source which is suitable for many applications. Of particular interest are high-charge, high-energy picosecond electron injectors for wakefield accelerators, linear colliders, medical and industrial radio-frequency linacs, and accelerator test facilities.
