Abstract:
A primary ion source subassembly for use with a secondary ion mass spectrometer may include a unitary graphite ionizer tube and reservoir base. A primary ion source may include a capillary insert defining an ionizer aperture. An ionizer aperture may be centrally arranged in an outwardly protruding conical or frustoconical surface, and may be overlaid with a refractory metal coating or sheath. Parameters including ionizer surface shape, ionizer materials, ionizer temperature, and beam stop plate orifice geometry may be manipulated to eliminate ghost images. A graphite tube gasket with a dual tapered surface, or an externally threaded graphite tubular connecting body, may promote sealing of a source material cavity.

Claim (Index 7):
The primary ion source subassembly of  claim 5 , wherein the reservoir base further comprises:\n a wall defining the internally threaded surface configured to receive the externally threaded surface of a tubular connecting body; and a shoulder arranged in a first annular cavity defined in the reservoir base and configured to receive the beveled primary sealing surface of the tubular connecting body when the reservoir base is engaged with the tubular connecting body.
