Bushing unit with integrated conductor in ion accelerating device and related method

摘要

An ion accelerating device includes a series of bushing units and a series of resistor circuit units. Each resistor circuit unit is coupled to one bushing unit. A bushing unit includes three integrated conductors to establish connections to the coupled resistor circuit unit and to an immediately adjacent bushing unit such that a voltage to the bushing unit may be degraded by the resistor circuit unit before reaching the lens and that two bushing units may contact one another directly.
