Abstract

An electron temperature gradient (ETG) is formed perpendicular to the magnetic field lines by superimposing lowerature thermionic electrons emitted from a tungsten hot plate upon higherature electrons of an electron cyclotron resonance plasma, which pass through two different-shaped mesh grids. The radial profile of the plasma space potential can be controlled independent of the ETG by changing the bias voltages of the hot plate.
