During the first two-year term of this grant and the first months of the second two-year term all the equip ment necessary to study fast chemical reactions with a shock tube and mass spectrometer were built. All the separate components were assembled, tested and in most cases modified to improve performance. Preliminary test results were obtained in the form of ion current-vs.-time curves for shocked pure argon and for dilute N2 in Ar. A preliminary test of the N20 dissociation reaction was performed. Several new ideas in shock tube instrumentation were developed and are discussed. A general description of the shock tube, mass spectrometer and all the supporting equipment is included. The shock studies in the nonreacting systems were conducted to calibrate the system and also to determine the limits of sensitivity and range of applicability of this method of studying reactions. Some of the early results are discussed.
