Abstract

To cover a so-called terahertz gap in available sources of coherent electromagnetic radiation, the gyrotron with a pulsed solenoid producing up to 50 T magnetic field has been designed, manufactured and tested. At 38.5 T magnetic field, the gyrotron generated coherent radiation at 1.022 THz frequency with pulse duration about 50 microseconds. The microwave power and energy per pulse were about 1.5 kW and 75 mJ, respectively. Details of the gyrotron design, manufacturing, operation and measurements of output radiation are given. The highest for gyrotrons generation frequency 1.3 THz has been obtained at 48.7 T magnetic field.
