A terahertz gyrotron oscillator with a pulsed solenoid producing up to an 8 T magnetic field has been designed, constructed and tested. In a 7.96 T magnetic field, 3 kW output power radiations at 0.22 THz frequency have been generated. %K terahertz %K gyrotron %K pulsed magnetic field %U http://link.springer.com/article/10.1007/s11434-009-0172-9
