The sparking probability of a test gap, to which short-duration direct high voltage pulses are applied, is shown to depend on the distance of the gap from a source of short wavelength, ultraviolet radiation. The radiation is restricted to a small volume of gas midway between the electrodes. The sparking probability can therefore be used as a parameter in examining the absorption of the radiation responsible for triggering a discharge in the gas. Absorption of ultraviolet radiation by the gases argon, air, nitrogen, and oxygen has been studied.

Birefringent Medium

An apparatus is described to measure the Kerr constant of conducting as well as non-conducting liquids and solutions. High-voltage pulses of short duration (1.5 μs) are applied across the Kerr cell and the resultant birefringence is measured by a novel signal-nulling technique. New expressions are derived for the null conditions for an optically active birefringent medium. Results are presented at 633 nm and 293 K for water, methanol, ethanol, propan-1-ol and propan-2-ol. The Kerr constant of water (3.0 × 10-14 m V-2) was in good agreement with recent determinations.

Delay Lines

A high voltage pulse lasting 0.35 microsecond is applied to a pair of delay lines, so that two pulses can be picked up from adjustable points of connection on the lines. One is applied to an irradiating gap and the other to a longer test gap, the gaps being so arranged that only mid-gap irradiation occurs. The sparking probability, P, of the test gap is used to indicate the presence of ionizing radiation. Variations of P with the time interval between the two pulses are recorded. They indicate that ionizing radiation is emitted in repeated short flashes. Photographic observations support this view.
