Injection of a high density plasma into a magnetic mirror was accomplished by generating plasma vortex rings under both mirror coils. Observations indicated that the rings move toward the center of the mirror and collide. Trapped magnetic fields in the rings produced a field reversal at the center of the mirror. The collision was followed by an oscillating motion of the ring currents flowing in the highly ionized plasma. Plasma was trapped inside the mirror for times of the order of milli-seconds. There was no recycling of the gas in the mirror system. The plasma thermalized and then left through the escape cones and by diffusion to the walls. The ion temperature was of the order of 200 eV. Plasma volume was approximately 1000cc. Confining field was 10kG. Author
