The Associated Electrical Industries levitron.
(Great
Britain) The levitron is a toroidal version of the linear hard core or inverse pinch discharge with the object of producing a hydromagnetically stable plasma, in addition to hydromagnetic instability, others may occur and it is the object of the authors to determine their nature and estimate their importance in energy and particle-loss processes. The normal working pressure in the torus is of the order of 3 × 10 -3 torr. Discharges have, however, been studied at pressures as low as 6 × 10 -5 torr and as high as 16 × 10 3 tort. Most of the work has been carried out with hydrogen, but several experiments were carried out with helium and argon. The levitron discharge is more stable than a toroidal pinch discharge and shows better isolation of the plasma from the walls of the torus. There is however still an instability, the nature of which is unknown. The maximum electron
