Yv. Vasilchenko et al., EVALUATION OF PHOTOMULTIPLIERS RESPONSE NONLINEARITY WITH NONCALIBRATED PULSE LIGHT-SOURCES, Instruments and experimental techniques, 39(4), 1996, pp. 552-557
A simple method for measuring and evaluation of nonlinearity of the ph
otomultiplier response efficiency using two controlled noncalibrated l
ight sources is presented. The accuracy of the response efficiency non
linearity evaluation and its linearization procedure was found to be 0
.15%. As was shown, a photomultiplier nonlinearity led to nonproportio
nal distortions of photoelectronic estimates.
