Abstract

A pulse counting method has been used to determine gains of an electron multiplier for various ions. A16-stage box and grid type electron multiplier with copper-beryllium dynodes has been employed in equipment to a single focusing mass spectrometer. The condition, where the gain determined by the pulse counting method becomes almost identical to that by a Faraday cup method for each of various ions, has been discussed.
