Abstract

An electron/ion pulse counting system was used for a high-counting-rate application under strong electromagnetic noise. The number of photoelectrons produced by a nonresonant multiphoton ionization of gaseous molecules was counted as a function of gas pressure in vacuum. The system was successfully operated under electromagnetic noise originated from a pulsed laser. The detector acted as a gated, accumulating counter with a capacity of 300 cps. A maximum counting rate of 2×1010 cps was experimentally achieved when laser-produced photoelectrons arrived within a gate of 15 ns.
