    Notes: Abstract Frequency detuning in the University of Sydney Gyrotron II has been measured for a number of modes in the vicinity of the TE0 14 1 mode at 183 GHz. The main features of the observations agree with theory and the importance of a detailed knowledge of the electron velocity distribution and the cavity Q's is established.

    Notes: Abstract In the course of developing a low-power, tuneable millimeter-wave source, two gyrotrons have been constructed. Gyrotron I was a fixed-frequency device operating at 120 GHz while Gyrotron II produced more than 20 lines in the frequency range 130 to 260 GHz. The design of tuneable gyrotrons is discussed with reference to the Gyrotron II results.

    Notes: Abstract The cavity of the University of Sydney gyrotron, GYROTRON IIIB, is split in two longitudinally to allow and frequency that lies between the fixed cavity resonances to be accessed by mechanically changing the separation of the two halves. The rate of change in resonant frequency with separation is greatest if the minor axis of the cavity cross-section is the one undergoing change. Results obtained with the latest cavity demonstrate this and show excellent agreement with theory.

    Notes: Abstract The observed output power levels in the University of Sydney's gyrotron can be accounted for only by including the effects of mode conversion at waveguidetaper transitions in the vicinity of the resonant cavity. A series of measurements taken from liquid-crystal images of the microwave fields beyond the output window confirms this.
