The paper presents the results of theoretical and experimental studies of W-band planar surface-wave oscillator driven by sheet high-current relativistic electron beam with experimentally realized parameters on the basis of the “SINUKI” accelerator (IAP RAS, N. Novgorod, 1 kА / 650 keV / 17 ns). In simulation of the oscillator nonlinear dynamics, we used both advanced quasi-optical approach and direct 3D PIC modeling. In the experiment, the microwave generation with a frequency of about 75 GHz was registered by microwave detector; measured pulse duration was about 4 ns. The output power measured by the calorimetric method was about 25 MW which is in a satisfactory agreement with the theoretical predictions. The important specific of the experimental set-up is the use of highly efficient side wall absorber for the implementation of a single-mode single-frequency generation regime. |
