ION HEATING DUE TO ROTATION AND COLLISION IN A MAGNETIZED PLASMA
The ExB rotation and associated collisional ion heating of noble gas magnetized plasmas are investigated with high resolution by means of laser induced fluorescence and electrical probes. Plasma rotation results from a radial potential gradient which can be controlled by biasing of the discharge electrodes. The time and space evolution of the potential, the rotation velocity nu-theta, and the ion perpendicular temperature indicate that heating is due to the randomization of nu-theta by ion - neutral collisions, and leads to temperature increases as high as a factor of 50 over initial values.
