  • Indirectly heated cathode ion source assembly
    Patent number: 10217600
    Abstract: The indirectly heated cathode ion source assembly employs a cathode cup unit and filament arrangement wherein the filament has a flat face spaced from a tungsten disc-shaped body and is disposed in a space that is surrounded by a thermal barrier to reduce thermal losses. The thermal barrier is formed by a plurality of concentric foils that are closely spaced.

  • Extraction electrode
    Patent number: 9793094
    Abstract: The extraction electrode has a pair of sub-assemblies that define a gap. Each sub-assembly has a suppression plate and ground plate secured together in spaced relation by pairs of insulating assemblies. A plate assembly extends perpendicularly from the ground plate. The gap between the subassemblies is set by tabs on a centering fixture extension.

  • Plasma arc chamber
    Patent number: 9159526
    Abstract: The plasma arc chamber is made in part of a one piece base fabricated from 95.95% pure tungsten having four rigid walls defining a rectangular central opening. A bottom plate closes the bottom of the base and a cover with a slit for the passage of an ion beam closes the top of the base. Liners are fitted into the bottom plate, the top of base and against the four walls of the base.

  • Filament clamp assembly
    Patent number: 9117623
    Abstract: The filament clamp assembly has a pair of clamps to hold the connecting leads of a filament. Each clamp employs a locking pin within a longitudinally disposed bore that is moved into clamping engagement with a filament lead by rotation of a locking nut that moves a stud with a camming surface into the clamp to lift the locking pin via the camming surface.
