Penetration of magnetic fields into plasmas and heating of a collisionless plasma by radio frequency waves. Progress report

Experimental work is completed on the effects of neutrals on magnetic piston and sheath development. A preliminary form of this work was presented at the American Physical Society meeting in November, 1975 and is included as appendix. In this work, the measurement and analysis of the current sheath with a data reduction to the microscopic collision frequencies, is also included. The rotation of the plasma during the implosion was detected. Indications are that observations of a nonradial component of the electric field can be related to plasma rotation. (auth)
