MINIATURE MASS SPECTROMETERS FOR UPPER ATMOSPHERE COMPOSITION MEASUREMENTS.

Abstract

A basic quadrupole mass spectrometer system for neutral and ionized gaseous composition measurements of the upper atmosphere is described. Emphasis is placed on the electronic circuits used with a particular miniature quadrupole rod assembly and ionizer. Circuits described include the power converter, scan waveform generator, dc and rf excitation generators, logarithmic output current amplifier, ion source filament emission regulator and signal-conditioning circuits for telemetering. A summary of performance specifications and critical design dimensions is included. (Author)
