Abstract

The fluorescence sensitized photomultiplier has been combined with a peak-reading pulse voltmeter to record intensities from a source of the Lyman continuum operated at a repetition frequency about 2 cps. Intensities can be measured on a linear scale to within a few percent. The variation of intensity with time during the 100 µsec following the pulse discharge has also been examined using sodium salicylate and calcium tungstate as fluorescent materials.
