A directed dense plasma was observed to penetrate and be detained by a vacuum cusp magnetic field. A gross measurement of the directed velocity of the deuterium plasma was (8.5 plus or minus 0.5) x 10/sup 6/ cm/sec. Ion density in the central region of the cusp was measured to be 8.5 x 10/sup 15/ at 16 mu sec after injection, and it had a decay constant of 13.5 mu sec. Magnetic probe measurements were shown which indicated the gross reaction of the magnetic field to the injected plasma. Observation of impurity eraission indicated that the plasma electrons cool rapidly and that the collision-dominated plasma is in contact with the container walls at the cusp ring. (auth)
