45 GHz/20 kW gyrotron-based system for ECR ION source

This paper describes gyrotron-based setup developed by Gycom Ltd. jointly with IAP RAS and intended for use in superconducting ECR ion source FECRAL (a Fourth generation ECR ion source with Advanced design in Lanzhou, China) [1]. The setup is capable to provide output power up to 20 kW in both CW and pulse (5–200 ms duration with less than 10 μs fall time and up to 5 Hz repetition rate) modes with 45 GHz frequency.
