Multiple-beam microwave tubes

The production of multiple-beam microwave tubes at the Russian research and production company ISTOK is discussed. MBKs (multiple-beam klystrons). TWTs (traveling wave tubes), and BWOs (backward wave tubes) provide low operating voltages, high power, low noise, and the possibility of larger operating bandwidth. The devices discussed include MBKs, pulsed multimode multiple-beam TWTs, and multiple-beam BWOs operating at wavelengths as short as 0.2 mm. These studies have shown that the use of multiple-beam designs provides a powerful means for improving the parameters of microwave tubes.<
