摘要: 正 (一)引言 電子迴旋脈塞(Gyrotron)作為一類新型的快波器件,可在毫米、亞毫米波段有效地產(chǎn)生高功率相干輻射,標志著微波電子學的一大突破。 Gyrotron與普通微波管在作用機理上有很大的區(qū)別。它采用光滑波導或過模諧振腔作為高頻結(jié)構,取代了傳統(tǒng)的慢波電路或諧振腔。Gyrotron為快波型器件,而微波管一般為慢波型器件。不久前,有人提出利用慢波互作用的變態(tài)迴旋脈塞器件即weibel型器件。Gyrotron快波型器件的作用機理來自迴旋脈塞不穩(wěn)定性,而Weibel型慢波器件的

Abstract: Starting from the view point of the coherent cyclotron radiation, we work out the phase condition of the Weibel instability gain mechanism and make a comparison with the phase condition of the cyclotron maser gain mechanism. Moreover, we propose a conceived slow wave cyclotron amplifier (SWCA) with a periodic rf structure. -
