Abstract
An instrument measures fluorescence which has occurred in a sample stimulated by X rays. The instrument consists of a laser device, an X-ray pulse generation tube excited by the laser pulse from the laser device, a light sensor for detecting fluorescence in the sample, a reference timing pulse generator, a time-to-voltage converter to indicate the time of fluorescence and a multichannel analyzer to sum the frequency of times that the designated voltage is issued from the time-to-voltage converter in each voltage level during measurement.
