A simple and low-cost pseudo-fixed dead time X-ray counting system is implemented for long-time stable accurate X-ray sampling in electron probe microanalysis (EPMA). The extendable dead time generator is inserted between the single-channel analyzer (pulse-height analyzer) and counter in this study. The dead time of the new design can be considered to be a fixed value when that originated by the proportional counter
and single-channel analyzer.
