Abstract

The experimental researches of DRO-orbictron mainly confirmed the conclusions of theoretical researches and showed perspective of the use in DRO resonance matching method of double grating with the ORS-field. The placing of double grating on the bottom of the matching groove gives the opportunity in substantially decreasing of ORS-mirrors aperture, and we can excite in the ORS only the basic TEM00q-modes. The increasing of efficiency for energy exchange between an electron beam and resonance field in DRO-orbictron is caused by gathering of the resonance field to the width of matching groove and do not accompanied by the growth of ohmic losses in a resonator. At the choice of the matching groove height to b ≈ 0,75λ the width of one-mode frequency tuning for DRO-orbictron exceeds 5,5%, and the output power arrives P = 10Watt at the beam current Ia = 130mA and the accelerating voltage Ua = 2,9 kV. The carried-out experimental researches of DRO-orbictron showed a perspective of use the given ORS in short-wavelengths DRO.

8-MM波段下反轨道器的实验研究

ro -orbictron的实验研究主要证实了理论研究的结论，并展示了双光栅与ors场的DRO共振匹配方法的应用前景。在匹配槽底部放置双光栅，使ORS-镜孔径有机会大幅减小，并且在ORS中只能激发基本的tem00q模式。电子束与谐振场之间能量交换效率的提高是由于谐振场聚集到匹配槽的宽度而引起的，而不伴随着谐振腔内欧姆损耗的增加。选择匹配槽高为b≈0,75λ时，ro -orbictron的单模频率调谐宽度超过5,5%，在束流Ia = 130mA，加速电压Ua = 2,9 kV时，输出功率达到P = 10w。进行的ro -orbictron实验研究显示了将给定的ORS用于短波ro的前景。
