A study has been made of r-f breakdown in which the controlling loss mechanism arises from the drift of electrons in an inhomogeneous magnetic field. The study was carried out using a toroidal system with parallel r-f electric and steady magnetic fields. An approximate averageelectron theory of drift- controlled breakdown is presented. Experimental measurements of breakdown r-f electric field versus magnetic field were made at various pressures from 1.25 to 6.0 x 10/sup -3/ mm of Hg, using hydrogen and helium gases. A radio frequency of 8-Mc/sec was used. Magnetic fields up to 2000 gauss were employed. The r-f breakdown field was found to vary as the inverse square root of the magnetic field as predicted by the theory. (auth)
