Abstract
For the EDDA experiment at COSY, the response of the small, linear foc used photomultipliers Hamamatsu R 1450 and R 1355 has been studied wit h fast light pulses generating yields up to 2 x 10(3) photoelectrons/c m2 or peak currents of 24 mA. Linearity was obtained with a tapered bl eeder chain at a tolerable loss of gain. The serial test of altogether 140 photomultipliers revealed the close correlation between single el ectron and amplitude resolution. The influence of the photoelectron st atistics on this correlation is discussed.
