Plasma heating by collisional magnetic pumping in a steady-state modified penning discharge

This paper describes the experimental application of collisional magnetic pumping to heat a plasma by a sawtooth magnetic perturbation, and provides results relating to the energy transfer process between the perturbed magnetic field and the parallel and perpendicular energy components of the heated species in a steady-state modified Penning discharge apparatus with a magnetic mirror configuration. Experimental data is discussed, and heating of ions and electrons as functions of magnetic induction, electron number density, and natural gas pressure is presented. The detailed design of the above apparatus is presented and discussed
