摘要： In accordance with one specific embodiment of the present invention, the ion optics for use with an ion source have a plurality of electrically conductive grids that are mutually spaced apart and have mutually aligned respective pluralities of apertures through which ions may be accelerated and wherein each grid has an integral peripheral portion. A plurality .of moment means are applied to a circumferentially distributed plurality of locations on the peripheral portion of each grid, which is initially flat, thereby establishing an annular segment of a cone as the approximate shape for that peripheral portion and a segment of a sphere as the approximate dished shape for the grid as a whole. The plurality of grids have conformal shapes in that the direction of deformation and the approximate spherical radii are the same. This elastic deformation during installation avoids any need for any permanent or inelastic deformation during fabrication, as well as controlling the excessive thermal displacements and accompanying performance changes to which flat grids are prone.

摘要： In accordance with one embodiment of the present invention, an end-Hall ion source has an electron emitting cathode, an anode, a reflector, an internal pole piece, an external pole piece, a magnetically permeable path, and a magnetic-field generating means located in the permeable path between the two pole pieces. The anode and reflector are enclosed without contact by a thermally conductive cup that has internal passages through which a cooling fluid can flow. The closed end of the cup is located between the reflector and the internal pole piece and the opposite end of the cup is in direct contact with the external pole piece, and wherein the cup is made of a material having a low microhardness, such as copper or aluminum.

摘要： In accordance with one embodiment of the present invention, the hollow-cathode (70) apparatus comprises a small-diameter tantalum tube (71) with a plurality of tantalum-foil radiation shields, wherein the plurality of shields (72a, 72b) in turn comprise one or more spiral windings external to that tube and approximately flush with the open end from which electron emission takes place. The axial length of at least one of the inner windings (closer to the tantalum tube) is equal to or less than approximately half the length of the tantalum tube. An enclosed keeper surrounds the cathode. To start the cathode, a flow of ionizable inert gas, usually argon, is initiated through the cathode and out the open end. An electrical discharge is then started between the keeper and the hollow cathode. When heated to operating temperature, electrons exit from the open end of the hollow cathode.
