Title: Formation of Collisionless High-{beta} Plasmas by Odd-Parity Rotating Magnetic Fields

Abstract

Odd-parity rotating magnetic fields (RMF{sub o}) applied to mirror-configuration plasmas have produced average electron energies exceeding 200 eV at line-averaged electron densities of {approx}10{sup 12} cm{sup -3}. These plasmas, sustained for over 10{sup 3}{tau}{sub Alfven}, have low Coulomb collisionality, v{sub c}*{identical_to}L/{lambda}{sub C}{approx}10{sup -3}, where {lambda}{sub C} is the Coulomb scattering mean free path and L is the plasma's characteristic half length. Divertors allow reduction of the electron-neutral collision frequency to values where the RMF{sub o} coupling indicates full penetration of the RMF{sub o} to the major axis.
