Monte Carlo Studies of Tandem-Mirror Plasmas Interacting with Waves in the Ion-Cyclotron Range of Frequencies (ICRF). Annual Report, October 1, 1982-September 30, 1983

摘要

A study of RF start-up, RF Fueling, and RF Anchor operation in Tandem Mirrors has been completed. Significant results include finding little performance difference between inboard and outboard antennas, and an optimum central-cell electron-to-ion-temperature ratio of between one and two. Several variance-reduction techniques, improved RF operators and a Monte Carlo neutral model have been incorporated in the code. Ongoing activities include studies of central-cell ICRF heating and hot-electron anchor operation of Tandem Mirrors, and Development of Monte Carlo non-maxwellian scattering operators. Completion of these ongoing activities, conversion of our Monte Carlo ICRF code to the NMECC CRAYS, and initial development of a new Monte Carlo RF code for 3-D mirror equilibrium geometries comprises our proposed program for FY '84.
