Abstract:

The following report reviews the work done in the design and fabrication of rocket borne quadrupole mass spectrometer electronic assemblies and ground support equipment. The electronic assemblies are integrated with a rod housing assembly, which is furnished by the government to make a complete spectrometer unit. The electronic units are designed to supply the necessary data handling circuits, the DC and RF sweep voltages, DC bias voltages, and a programmer which controls the sweep amplitude, time and shape. The mass spectrometers are used to measure positive and negative ion and neutral constituents in the upper atmosphere.
