  • Glass-like insulator for electrically isolating electrodes from ion implanter housing
    Patent number: 6291828
    Abstract: An electrostatic quadrupole lens assembly (60) is provided for an ion implanter (10) having an axis (86) along which an ion beam passes, comprising: (i) four electrodes (84a-84d) oriented radially outward from the axis (86), approximately 90° apart from each other, such that a first pair of electrodes (84a and 84c) oppose each other approximately 180° apart, and a second pair of electrodes (84b and 84d) also oppose each other approximately 180° apart; (ii) a housing (62) having a mounting surface (64) for mounting the assembly (60) to the implanter, the housing at least partially enclosing the four electrodes (84a-84d); (iii) a first electrical lead (104) for providing electrical power to the first pair of electrodes (84a and 84c); (iv) a second electrical lead (108) for providing electrical power to the second pair of electrodes (84b and 84d); and (v) a plurality of electrically insulating members (92) formed of a glass-like material, comprising at least a first electrically insulating member for

  • Compact helical resonator coil for ion implanter linear accelerator
    Patent number: 6208095
    Abstract: A compact coil design is provided for a linear accelerator resonator (70) capable of resonating at a predetermined frequency. The coil (90) comprises a plurality of generally circular coil segments (90a-90n), each of the coil segments having a polygonal cross section wherein flat surfaces (122) of adjacent coil segments face each other. The polygonal cross section may take the form of a rectangle having dimensions of length x and width y, wherein dimension x section defines the flat surfaces (122) of adjacent coil segments (90a-90n). The coil segments (90a-90n) are provided with a dual channel construction for providing the introduction of a cooling medium into the coil. The dual channel construction comprises an inlet passageway (118) and an outlet passageway (120) having separate a separate inlet (100) and outlet (102), respectively, at a first end (94) of the coil, and wherein the inlet and outlet passageways (118, 120) are connected and in communication with each other at a second end (96) of the coil.
