Abstract :
In this paper, we present the experimental cold-test results of the new input cavity and the hot tests of this new 4 cavity, frequency-doubling coaxial gyroklystron. The input cavity was redesigned to have a lower quality factor and located the lossy absorbers inside the cavity structure, rather than in the adjacent drift tube sections. The average radius of the cavity was increased to make that cavity less susceptible to spurious oscillations. The designed 4 cavity frequency doubling system have a high large signal gain above 50 dB.
