HYPERBOLOID MASS SPECTROMETER WITH ONE-DIMENSIONAL ION SORTING FOR DIAGNOSTICS OF A PLASMA
DOI: 10.1615/ITPPC-1998.400
pages 265-270
Abstract
A new hyperboloid mass spectrometer with ion separation along one axis was examined. The electrode system consists of two electrodes, each of these has accurately machined hyperbolic internal surfaces, with a shielding electrode. An impulse signal is used, which provides phase ion injection into a field free volume of the analyser. An estimated trapping coefficient of analysed ions and a sorting rate predict high efficiency of the suggested separation method and its capabilities. The achieved mass resolution is about 103.
