Surface loss coefficients of CFx and F radicals on stainless steel

The surface loss coefficients of CFx (x51 – 3) and F radicals have been measured on the stainless steel walls of the differential pumping systems of a plasma reactor. This measurement is made by comparing the beam to background signal ratio of the radicals measured by...

Quantification of a Radical Beam Source for Methyl Radicals

A radical beam source for methyl radicals (CH3) was characterized applying ionization-threshold mass spectrometry. The beam source is based on thermal dissociation of methane (CH4) or azomethane (N2~CH3!2! in a heated tungsten capillary. A flux of (361)31013 cm22 s21...
