Average Charge Detector for Mass Spectrometers

Abstract
The results of space experiments designed to determine the intensity and energy distribution of the solar plasma have been somewhat ambiguous because of the inability to provide separate measurements for the H+ and He++ components of the plasma stream. An instrument has been designed which can provide the required separation with adequate accuracy. Performance data for the instrument presented as a function of ion beam intensity and energy indicate a repeatability of the order of 3%. Data on measurement sensitivity to experimental variables suggest that the repeatability might be significantly better than is indicated by current results.
