Abstract :
Initial tests of a fast-millimeter-wave wide-band gyrotron traveling-wave amplifier (gyro-TWA)of novel design have demonstrated a small-signal 3-dB bandwidth of 13 percent with 18-dB gain at midband (35 GHz)using a 70-kV 1-A annular electron beam. This reflection-type amplifier using the TE01circular-electric mode has a linear tapered Waveguide circuit with an axial magnetic field profiled to maintain synchronism.
