Abstract
OBSERVATIONS have been made of the light emitted from the positive and negative point surge corona discharges. The photomultiplier used for measuring the light, together with its associated distributed amplifiers with a rise time of not more than 10−8 sec., and the recording oscillograph, were contained in a double-screened cage with a filtered mains-supply to eliminate large spurious signals originating from the surge generator. The time base of the oscillograph was tripped from a pulse derived from the corona itself via a second photomultiplier so that fast time sweeps could be used.
