Ionic and neutral reactions in glow discharges of a He--SO/sub 2/--CO mixture
Mass spectrographic studies have been conducted on the positive ions and neutral species of glow discharges containing 1.0 percent SO/sub 2/ and 1.0 percent CO in helium. Measurements were conducted for gas pressures from 3.5 to 10.1 torr using both dc and 60-Hz ac excitation. The ion species that were observed included S/sup +/, SO/sup +/, SO/sub 2//sup +/, O/sup +/, O/sub 2//sup +/, C/sup +/, CO/sup +/, and CO/sub 2//sup +/ with lesser amounts of SO/sub 3//sup +/, (CO)/sub 2//sup +/, SCO/sup +/, and (SO . CO)/sup +/ or CS/sub 2//sup +/. Interpretation of the functional dependence of the various ionic and neutral species on pressure and applied power showed that CO reacted with the SO formed in the discharges to produce CO/sub 2/ and sulfur. Deposition of elemental sulfur was observed in the plasma container.
