The Effect of Ion Mass and Ion Energy on the Sensitivity of Ilford Q 2 Plates as Ion Detectors in Mass Spectrography

Abstract

The sensitivity of llford Q₂ photographic plates as detectors in mass spectrography has been investigated. The dependence of the sensitivity on the mass and energy of the impinging ions has been determined from the relative darkening of the emulsion produced by a fixed number of ions of mass 13 through 198 accelerated by voltages between 1.88 and 15 kv The sensitivity was found to increase with increasing ion energy and to decrease with ion mass.
