Impact ionization effect

WitrynaElectron impact ionization (ei) is by far the most commonly used ionization method. The effluent from the GC enters a partially enclosed ion source. Electrons “boiled” from a hot wire or ribbon (filament) are accelerated typically by 70 V (and thus have 70 eV of energy) before entering the ion source through a small aperature. Witryna3 maj 2024 · The electron impact ionization (EII) cross-section can be obtained by replacing one bound orbital in the final state with the free orbital of the ejected electron in the above EIE expression. ... Furthermore, the plasma screening has a stronger effect on the ionization of the outer-shell electrons than the inner-shell electrons. Taking the …
