A floating electrostatic sheath in a thermally produced plasma
Abstract
Measurements are reported of the plasma density in a highly ionized, thermally produced plasma. A floating-electrostatic-sheath theory is presented which predicts that the plasma density is enhanced by several orders of magnitude above the level which would be predicted in the absence of such a sheath. There is agreement between the measured variation of the plasma density as a function of temperature and the predicted behavior.
