Abstract
Improvements for viewing particles, e.g. electrons or ions, in mass spectrometer systems. A special kind of system allows a phosphor to be formed which does not include any kind of conductive layer thereon. The particles impinge directly on the phosphor, and produce light that shines through an ITO layer. This special system enables lower voltage, and smaller systems. Another improvement enables direct viewing of ions from the system.
