Plasma shape and finite {beta} effects on stability thresholds of the ion temperature gradient modes
Abstract
The stability of electromagnetic ion temperature gradient driven modes with emphasis on the lower and upper stability thresholds is investigated by a collisionless magnetized plasma in both circular and noncircular geometry. The stability properties are discussed and the results are compared for finite {beta} effects, arbitrary elongation, and Shafranov shift rate parameters. It has been found that the lower stability thresholds are weakly dependent on the (combined) effects of Shafranov shift rate, finite {beta}, and elongation whereas the second (upper) stability regime shows substantial dependence depending on parameter regimes.
