Development of a continuously frequency tunable gyrotron operating at the fundamental resonance for 600 MHz DNP-NMR spectroscopy

Continuously frequency tunable gyrotron, FU CW VIB, which is of sealed-off type has been developed for 600 MHz DNP-NMR at FIR FU. The frequency tuning bandwidth reached 1.4 GHz. The output power was ranged from 15 to 130 W.
