A high power sub terahertz pulse gyrotron is under development in FIR-FU for application to collective Thomson scattering from a high density plasma in the large helical device. As a step to the final goal, a second harmonic gyrotron using a newly designed electron gun was fabricated aiming at 50 kW at around 400 GHz. Oscillation modes were carefully selected from the view point of mode separation...
A high power sub terahertz pulse gyrotron is under development in FIR-FU for application to collective Thomson scattering from a high density plasma in the large helical device. As the first step of this development, a pulse gyrotron using an existing electron gun was constructed and tested. Oscillations with frequencies around 400 GHz was observed at the second harmonic resonance. Several modes were...
