Abstract
The present invention is an anode cathode parallelism gap gauge. The gauge is for determining the relative parallelism between two planar surfaces such as an anode and cathode in a relative ion chamber. The gauge sits on the anode on three points and then has the cathode extended into its volume. The cathode will then contact the measuring arms, of which there must be at least three, that statically latch measurement values onto a scalar device. Thus, the present invention provides a reliable and clean method of determining parallelism and distance between an anode and cathode or other surfaces.
