  • Abstract
    Physical design studies towards DEMO-compatible gyrotrons (frequency above 230 GHz, output power above 1 MW, frequency-tunable) have been started at KIT. Usage of very high-order modes (eigenvalue above 120) is necessary and allows a novel mode-selection strategy. Two different resonator designs for 237.5 GHz gyrotrons are under investigation.
