    Abstract

    Following on from the successful operation of a broadband, high-power gyrotron traveling wave amplifier (gyro-TWA) in W-band, experiments were carried out to demonstrate the versatility of the gyro-TWA and investigate its tuning characteristics. When operating at a lower voltage of 40 kV, 30 dB gain was achieved for a 1 GHz bandwidth frequency-swept input signal.
