Abstract
The design and construction of an ion source designed for the MS‐9 mass spectrometer are described. The source is designed to operate at ion chamber pressures up to 2 Torr while the pressure in the remainder of the source housing does not exceed 2×10−4 Torr. It is possible with this source to study ion‐molecule reactions, i.e., chemical ionization mass spectrometry. Alternatively, if operated at lower ion chamber pressures, the source provides normal electron impact mass spectra and is thus a dual‐purpose source. Modifications necessary to the MS‐9 are described, as are performance characteristics of the new source.Keywords
