摘要：
We describe the results of studying experimentally a high-power (hundreds of kilowatts) pulsed (pulse duration of about 30 μs) subterahertz gyrotron with the generation frequency corresponding to one of the atmosphere transparency windows. The gyrotron with an operating frequency of 0.67 THz, a power of more than 200 kW and an efficiency of 20–25% was used in the experiments on ignition of a localized discharge in a plasma. The paper presents the data about measurements of the temperature field of the emitter, calorimetric measurements of the power and efficiency of the gyrotron, and the design of the quasioptical converter of radiation to a narrow wave beam. The first experiments with the terahertz discharge in a focused wave beam of the gyrotron are briefly described.
