已经实现了由管状电子束300 keV / 100 A / 3 μs驱动的圆柱形几何形状的Ka波段表面波振荡器。使用具有二维波纹的周期结构实现了超大型系统（周长与波长之比约为 16）中的窄带振荡区域。获得了1.5-2MW级别的输出功率。证明了振荡频率相对于电子束参数的变化的高稳定性。根据模拟结果，频率稳定是由二维波纹结构提供的横向（方位角）能量通量的存在引起的。开发基于“SINUS-6”加速器（500-700 keV/4 kA/20 ns）的Ka波段亚吉瓦表面波振荡器项目。
Ka-band surface wave oscillator of a cylindrical geometry driven by tubular electron beam 300 keV / 100 A / 3 μs has been realized. Narrow-band regime of oscillations in strongly oversized system (perimeter-to-wavelength ratio is about 16) was achieved using periodical structure with two-dimensional corrugation. Output power of 1.5–2 MW level was obtained. High stability of the oscillation frequency with respect to variation of the electron beam parameters was demonstrated. In accordance with the results of simulations, frequency stabilization is caused by the presence of transverse (azimuthal) energy fluxes provided by 2D corrugated structure. The project of a Ka-band sub-gigawatt surface wave oscillator based on “SINUS-6” accelerator (500–700 keV / 4 kA / 20 ns) is developed.
