PHOTOELECTRON DETECTION EFFICIENCY OF HIGH-GAIN IMAGE INTENSIFIER SYSTEMS USED WITH SCINTILLATION CHAMBERS
Journal Article

· Nucl. Instr. Methods
ABS>The method described for measurement of photoelectron detection efficiencies requires that a weak light source illuminate the photocathode of the first stage of the image intensifier system, and that the resulting electron current be measured. The light is then reduced by a known large factor so that the number of electrons emitted under these conditions is known. The number of electrons reaching the phosphor is attenuated by pulsing the tube. Photographs record the corresponding number of spots. Results of one series of measurements are shown. (A.G.W.)
