Abstract :
The possibility of improving bunching and rising efficiency by using a cavity that operates at the second harmonics of working frequency has been studied. This possibility is realized in relativistic gyroklystrons with rather high-density electron beams. The three-cavity gyroklystrons with full length l=5.2/spl lambda/, accelerating voltage V/sub 0/=425 kV, and beam current I/sub 0/=160 A have been studied. In this letter, a new solution to the problem of electron-phase-bunching improvement in gyroklystrons is suggested. It allows one to design a new construction of gyroklystrons 10% more effective than traditional designs.
