Abstract : An Ion Mass Spectrometer and supporting Sounding Rocket System were developed to make in situ measurements of cluster-ions in the D-region of the ionosphere. A cryogenically vacuum-pumped quadrupole mass filter and secondary emission ion counter are coupled to make mass spectral measurements of positive and negative ion composition in ambient gas sampled at the apex of a cone designed to attach the shock wave induced by supersonic sounding rocket speeds.
