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 5):
The primary ion source subassembly of  claim 4 , wherein the reservoir base further comprises a beveled primary sealing surface configured to mate with a shoulder arranged in the cavity of the cavity-defining reservoir body when the reservoir base is engaged with the cavity-defining reservoir body.
