IMPROVEMENTS IN ION SOURCES
Patent
·
OSTI ID:4834070
An ion source for mass spectrometers is designed for ion outputs which are more abundant and more representative of the true isotopic composition of the sample ionized. The ion source, operated without a magnetic field, comprises a filament for emitting electrons, an accelerating grid, a plate at a potential negative to that of the filament, and a fourth electrode at a potential highly negative to that of the plate and having a slit for extraction of the ions. The potential of the filament is negative to that of the grid. (D.L.C.)
