Compact Electron Cyclotron Resonance Accelerator

A class of novel electron accelerator, electron Cyclotron Resonance Accelerator (eCRA) [1], is under the development to be remarkably-compact and highly efficient to produce high power electron beams and x-ray beams for medical, research, sterilization, and national security applications, so as to replace radioactive materials. The eCRA has several attractive features including: a compact robust room-temperature single-cell RF cavity as the accelerator structure; and a high-current self-scanning accelerated energetic e-beam, obviating need for a separate beam scanner. Numerical simulation and on-going experimental efforts will be reported here.
