    The AAEC ROTAMAK experiment description and preliminary results at low input power.
    (Australian Atomic Energy Commission, 1984-12) Durance, G; Hogg, GR; Tendys, J
    A description is given of the initial experiments on a rotamak device operating with 10 kW input power at a frequency of 1.85 MHz. The experimental apparatus and the diagnostic systems are also described. The matching of the radiofrequency power sources to the drive coils is discussed and details are given of the results from discharges in hydrogen, deuterium helium, and argon. The plasma/magnetic field configuration appears to be stable although under certain conditions fluctuations of the magnetic field structure have been observed.

    A comparison of measured and calculated 238U/235U fission rate ratios for natural U02 rod-cluster fuel elements in the Zerlina Reactor
    (Australian Atomic Energy Commission, 1972-08) Durance, G; McCulloch, DB
    Experimentally measured values of the 238U/235U fission rate ratio 628 in uranium dioxide cluster fuel elements in a heavy water moderated, light water cooled reactor lattice configuration are compared with the predictions of one-group Monte Carlo cell calculations (MONTE), corrected for the actual experimental environment. A comparison between MONTE and WIMS calculations for the experiments is also given.

    The effect of an applied toroidal magnetic field on ROTAMAK discharges
    (Australian Atomic Energy Commission, 1984-12) Trowse, J; Durance, G; Hogg, GR; Jones, IR; Tendys, J
    The effect of an applied toroidal magnetic field upon the rotamak configuration has been investigated. It has been found that the configuration can be maintained for at least several milliseconds but it has not been unambiguously established whether the addition of the toroidal field is beneficial or detrimental to the rotamak discharge.

    Effects of rotating field frequency on the ROTAMAK configuration.
    (Australian Atomic Energy Commission, 1984-12) Durance, G; Hogg, GR; Tendys, J
    Experiments have been undertaken at three rotating field frequencies 1.0 1.85 and 3.5 MHz to determine the effect upon the rotamak configuration and the driven toroidal current. Toroidal current has been driven at all three rotating field frequencies for each of the gases studied. The results indicate that the 1.0 MHz frequency chosen for the rotating field in the high power AAEC rotamak experiments appears to be satisfactory.
