Neutral-injection plasma in the Culham levitron

OSTI ID:4429406
From third international symposium on toroidal plasma confinement; Garching, Germany (26 Mar 1973). The Levitron has a 30-cm major radius floating superconducting ring carrying up to 500 kA. Current supported with the aid of vertical field coils which are also used to determine the shape of the magnetic surfaces, and consequently the minimum-average-B properties. A beam of 5-keV neutral atoms was injected and trapped in a toroidal experiment. There appears to be no anomalous loss of these injected ions at least for times of 4 msec. The resulting cold plasma produced by their ionization of the gas has a lifetime of several hundred millisceonds which, provided no additional loss of plasma occurs, should be sufficient to allow exponentiation to higher densities where heating from the injected ions becomes significant.
