A new type of high-power electronic device—a gyroton with a corrugated resonator—is described and investigated. Spatial bunching of the electron beam does not occur in this device, however, highly efficient electron beam power conversion into the rotating electromagnetic field power is possible. The rectilinear electron beam deviates from the axis by the slow TM11 wave, then it gives up longitudinal energy to the same wave with more than 78% efficiency, and an output power up to 30 MW. The developed mathematical model of the interaction of the relativistic electron beam with an irregular circular waveguide and resonator fields presented in this article can be used to calculate and optimize the processes occurring in various microwave electronic devices, such as gyrotrons, gyrotons, TWT, Gyro-TWT, and BWT.

“…Previously proposed traveling wave gyroton [4] is based on the anomalous Doppler effect [6,15]. The calculated TM 11 wave phase velocity is less than the longitudinal velocity of electrons, and the following equation is satisfied…”

Аннотация -Рассмотрены вопросы создания нового типа генератора на открытом гофрированном резонаторе. Особенность такого генератора состоит в отсутствии пространственной группировки электронного потока. Электронный поток, прямолинейный на входе прибора, за счет своего начального отклонения от оси замедленной волной E 11 отдает свою продольную энергию этой волне. При этом возможно достижение высокого КПД (порядка 74%) преобразования мощности электронного потока в мощность электромагнитной вращающейся волны.

Absbact -In work the theory ofGyroton with a wide electron beam is constructed. Optimum regime of Gyroton with a wide electron beam are investigated. Frequency characteristics of Gyrotons, goffer and magnitostatic distributions are received. Dependence of gyroton efficiency on width of an electron beam is determined I. Introduction The Gyroton is new type ofthe electron device [I-41. The principle of its action cardinally differs from processes in girotron and consists that the rectilinear electron beam cooperates with rotating slowed down electromagnetic wave E,, of type. The electron beam deviates an axis of the device under action of a cross component of a magnetic HF field and then gives the longitudinal energy to a longitudinal component of HF electric field. Thus any longitudinal or cross bunching of an electron beam does not occur. Synchronism of interaction of an electron beam with the slowed down rotating wave is set by the wave E l l and supported by longitudinal magnitostatic field. It is obvious. that the slowed down wave such as E , , cannot be distributed in a waveguide not being transformed in H I , . It's waves are interconnected. Therefore calculations of a Gyroton can be carried out only at the account of both types of waves.Results of calculations. The some characteristics of Gyrotons have been given in [ 5 ] . There it has been shown, that the Gyroton with a thin electron beam and a regular goffered waveguide can have efficiency coming nearer to 100 %. The basic role in work of the device belong to wave Ell, however in this process not last role to wave H,,. Without taking into account a wave HI, the gyroton efficiency achieves the same level. but at other parameters of waveguide and magnitostatic field. At increase a width of electron beam the Gyroton efficiency decreases, but it is not so essential. Fig.1 shows, that with increase in radius of electron beam fiom dr=2nAr/h=O up to dr=0.9 the efficiency decrease from 97 % up to 40 %. Calculations were cai-ried out on five layer models of electron beam.
