The transparent cathode was found to improve relativistic magnetron operation by providing faster start of microwave oscillations at a predetermined mode without mode competition. Comparison of output microwave pulses produced by the microwave pulse compressor equipped with a mechanically operated switch and a fast gas-discharge switch showed that the latter one sufficiently shortens the rise time of the output microwave pulse.  Results of this research suggest that: i) the use of a transparent cathode in relativistic and, probably, nonrelativistic magnetrons provides better mode selection by locking the desired magnetron oscillations in a shorter period of time, and ii) the use of a faster switch (as fast as possible) in a waveguide of a microwave pulse compressor shortens the rise time of the compressed output microwave pulse.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783846548813\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783846548813","offer_id":39493550375005,"sku":"9783846548813","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/4db68d10-d761-4707-a046-07effd92a1c2.jpg?v=1770447547","url":"https:\/\/shop.autorenwelt.de\/products\/methods-to-produce-short-pulse-high-power-microwaves-von-andrey-d-andreev","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
