Description
Cyclotron Resonance Accelerator has several attractive features including: a compact robust room-temperature single-cell RF cavity as the accelerator structure; continuous high current accelerated dc beam output with self-scanning, obviating need for a separate beam scanner.
An electron accelerator version, electron Cyclotron Resonance Accelerator (eCRA) [1], is under the development to be highly compact and 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. Progress on the eCRA development, including numerical simulation, engineering design, and on-going experimental efforts will be reported here.
And an deuteron accelerator version, the deuteron Cyclotron Auto-Resonance Accelerator (dCARA) is presented here as well. Simulations predict that dCARA will produce a high-current multi-MeV beam of accelerated deuterons which could be highly competitive with that produced either with linacs or cyclotrons for an application to produce, via deuteron stripping, a high flux of neutrons with an energy spectrum centered near 14.1 MeV, as needed for testing inner-wall materials for a future deuterium-tritium fusion power reactor.
