A special demountable cathode-ray tube was designed to produce electron- beam excitation of organic scintillator solutions. Solutions were irradiated through an electronpermeable window. The beam was swept across the window in 0.4 x 10^-9 seconds. A 1P28 photomultiplier and traveling-wave oscilloscope was used in recording. About 25,000 Mev of excitation energy was delivered per pulse and pulse oscillograms were free of statistical variations. System response time was due almost wholly to photomultiplier transit-time dispersion. A pure Gaussian form was assumed for the response function of the system in analyzing pulse contours. The time resolution of the system was adequate to permit observation of the dependence of pulse rise times on concentration in solutions of pterphenyl in toluene and anthracene in benzene. The results were m good agreement with the energy-transfer theory proposed by Kallmann and Furst.
