A balloon-borne, radio-frequency mass spectrometer was constructed under this contract. The package is designed to study the ambient positive ion and more abundant neutral molecules of the upper stratosphere. The range of the mass spectrometer is 1 to 150 amu, with a resolution which can be set to better than 1 amu over that range. Titanium sublimation is used to pump the bulk of the gas load, with assistance from a liquid helium CO2 frost pump.
