ABSTRACT:
A radiation detector of the gas-filled counter tube type which has a reduced count rate drift. An electrically conductive coating is applied to the interior insulating surfaces in proximity to the anode wire of a gas-filled counter tube structure having an axially disposed wire anode. The electrically conductive coating is maintained at the same electrical potential as the anode and accumulated charges in proximity to the anode are thereby eliminated. Alternately, the electrically conductive coating applied to the interior insulating surfaces in proximity to the anode may be maintained at the same electrical potential as the outer conducting cylinder in order to eliminate accumulated charges. The elimination of accumulated charges in proximity to the anode significantly reduces count rate drift and hence improves detector performance.
