Abstract
WITH a point-to-plane gap geometry, a visible (corona) discharge can occur at much lower values of applied gap voltage than those necessary to cause spark breakdown. Such a positive-point d.c. corona discharge in room air has been studied by recording the light emitted with an 11-stage photomultiplier. The output from the photomultiplier was delayed, amplified by ‘distributed’ amplifiers1, and displayed on a high-speed cathode ray oscilloscope. The time base of the oscilloscope was triggered by the output of light through a separate photomultiplier, distributed amplifier and thyratron trigger circuit.
