Abstract:A 1.5 MW, 110 GHz gyrotron is under development for electron cyclotron resonance plasma heating in the DIII-D tokamak at General Atomics. The research is aimed to provide reliable CW operation of the m o t r o n at high efficiency. The gymtron design is based on previous successful results from the 1 MW gyrotrons built by Communication and Power Industries (CPI). A TE22.6 mode cavity is utilized with an electron beam voltage of 96 kV and a beam current of 40 A. The cavity is designed to avoid mode competition … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
