Plasma chemistry and surface processes of negative ions
This work reviews formation processes of negative ions in low-pressure laboratory plasmas. There are many topics of discussion in the chemistry of negative ions. In most studies only volume production by dissociative electron attachment is considered. However, a typical problem is that experiments reveal higher negative ion densities than one would expect based on attachment rates to ground-sta...
متن کاملCharging of dust grains in a plasma with negative ions
The effect of negative ions on the charging of dust particles in a plasma is investigated experimentally. A plasma containing a very low percentage of electrons is formed in a single-ended Q machine when SF6 is admitted into the vacuum system. The relatively cold Q machine electrons Te 0.2 eV readily attach to SF6 molecules to form SF6 − negative ions. Calculations of the dust charge indicate t...

15 صفحه اولLower-hybrid waves in a plasma with negative ions
The introduction of an electronegative gas (i.e., a gas with a large electron attachment cross section, e.g., SF6) into a plasma has made it possible to study plasmas in which the negative ion density can be much larger than the electron density. lp2 In such a plasma, new phenomena may be expected to occur, in particular, various electrostatic wave modes are modified by the presence of negative...
