Abstract
Resistors have successfully replaced corona point discharge devices in the control of high voltage gradients, such as those experienced in electrostatic accelerators. An improved resistor for such applications which has a single elongate resistive element, one end of which is mounted on a metal clamp which is adapted to be clamped to the edge of a metal disc of the type used in a supporting column or tube of an electrostatic accelerator. The other (free) end of the resistor is unsupported, but carries a tubular capacitive electrode, which provides, with a cylindrical metal housing which is mounted on the clamp coaxially with the resistive element, a spark gap. The free end of the resistor also supports a light-weight connector, into which or on to which a plug can be inserted or affixed to make an external electrical connection to the resistive element.
