In the low aspect ratio torus experiment (LATE) device, plasma current is initiated and ramped up to 20 kA solely by microwave power at the electron cyclotron (EC) range of frequency with a ramp of the external vertical field B(v) for the radial equilibrium of plasma torus at larger currents. Measurements suggest that an energetic electron tail in the energy range of about 200 keV carries the current. The line averaged electron density is higher than the plasma cut or density, suggesting that tail electrons might be driven by electron Bernstein waves mode-c onverted from the launched electromagnetic waves.
