Abstract
The results of experimental studies evaluating the influence of longitudinal slits in a conical diffraction outlet, combined with an electron collector, of a 10 GHz relativistic BWO (Backward-Wave Oscillator) with an operating mode TM01 are presented. It has been shown experimentally that replacing a solid conical waveguide with a similar longitudinal-slotted waveguide has little effect on the performance of the BWO. The use of a longitudinally slotted diffraction outlet instead of a continuous one makes it possible to reduce the volume of plasma and microparticles formed on the diffraction outlet surface under the action of an electron beam, and to improve their adsorption and removal.
期刊介绍：
Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
