Paper Abstract

Today's mass spectrometers provide data to the researcher in two modes: (1) in the form of a photographic plate where line densities provide integrated ion abundances, and (2) in the form of a strip chart recording where peak intensities provide ion abundances during a mass versus time scan. Both types of data suffer from low sensitivity - the former due to the insensitivity of photographic emulsions to positive ions (104 ions required for a detectable line) and the latter from a low duty cycle due to spectral scanning (typically 10-2 - 10-4). This paper describes the development of an electro-optical ion detector combining the best features of photographic and electrical ion detection (i.e., wide mass range coverage and low ion detection threshold respectively). A nineteen fold fiber optic image dissector is discussed which reformats the 1 mm x 361 mm mass spectrometer focal plane format to a 19 mm x 19 mm format suitable for vidicon imaging and electronic display of the data.
