Low-pressure inductive discharges

Formation of XeI(B) in low pressure inductive radio frequency electric discharges sustained in mixtures of Xe and I2

Low pressure excimer discharges ~,1–5 Torr! are of interest for use as ultraviolet sources for lighting applications. XeI(B) is an attractive candidate for excimer lamps due to the low corrosive properties of iodine. The excimer is thought to be formed by either harpoon or ion-ion recombination reactions, the latter of which requires a third body. The formation of the excimer at low pressures i...

Large effects of small pressure changes in the kinetics of low pressure glow discharges

The effect of comparatively small pressure changes on the composition of low pressure hollow cathode DC discharges is investigated with a combination of experimental diagnostic techniques and simple models of the plasma kinetics. The plasma precursors considered are H2, Ar/H2 mixtures, and air. In all cases, sudden characteristic composition changes are observed in the pressure interval between...

Abnormal heating of low-energy electrons in low-pressure capacitively coupled discharges.

In low-pressure capacitively coupled plasmas, high-energy electrons are collisionlessly heated by large rf fields in the sheaths while low-energy electrons are confined in the bulk plasma by the ambipolar potential. Low-energy electrons are typically inefficiently heated due to their low collisionality and the weak rf electric field present in the bulk. It is shown, however, that as a result of...
