Abstract

A different method of measuring the quantum noise characteristic of image intensifier tubes is described. This method consists of measuring the transmission of primary radiation through the entire tube and, by correcting for the attenuation losses in the input and output windows, calculating the fractional number of x-rays incident on the tube that is actually detected by the input scintillating screen. The results of these measurements for several image intensifier tubes are presented and discussed. The results show that this measurement method is capable of distinguishing one tube from another as far as quantum detection is concerned. This measurement method has been found useful for measuring and spe-cifyin the noise characteristic of image intensifier tubes.
