Abstract

A photomultiplier tube gain-suppression technique has been applied to a Thorn EMMI 9828B red sensitive photomultiplier. The gain-suppression mechanism and characteristics has been studied by measurement of the output changes of the photomultiplier during the application of the gain-suppression pulse while subjected to a constant incident light. Experimental results show that the 9828B photomultiplier tube can provide, at least, a two-step gain response for a constant incident light, when the gain-suppression pulse satisfies certain conditions. The application of the multiple-gain response of the PMT for the simultaneous measurement of photoluminescence of molecules of biological/biomedical importance is discussed.
