title: Threshold sensitivity and noise ratings of multiplier phototubes.
abstract: This paper deals with the various methods of specifying the noise characteristics of multiplier phototubes. Particular attention is paid to the different sources of noise, including thermionic emission from the photocathode, spurious dark emission, leakage current, background flux, and the random photon fluctuation of the signal flux itself to be detected.
