Web26 mrt. 2024 · The term “ ionization chamber ” is used to describe those detectors that are based on the principle of excitation or ionization of atoms of the medium through which the incident charged particles pass. The charged particles while passing through matter leave along their paths a chain of ionized or excited atoms which can be detected and counted. WebIONISATION –Electron Impact Ionisation (EI) • Operation depends on the conversion of gas molecules into charged particles, typically positive ions / fragments. • Achieved by electron impact ionisation via thermionic emission from a hot filament. • A typical current is 1x10-4Amps. • Ions extracted into the mass filter.
