Anderson, J.; Aiken, A.; Buelow, S.; Arrington, C. A.; Jones, B. Optical and Mass Spectral Studies of Shocked Salts and Polymer Films. Presented at the 13th APS Topical Conference on Shock Compression of Condensed Matter,Portland, OR, 2003.
Results from experiments examining shock-induced chemistry will be presented. A laser driven flyer was used to produce shocks in salts and polymer films coated on stainless-steel substrates. Shock intensities ranged to 25 GPa. Ions produced by the shock interaction were collected and analyzed by a time-of-flight mass spectrometer. Experiments examining shocked inorganic salts produced simple, easy to interpret spectra. The spectra indicated the breaking of both ionic and covalent bonds in the shocked salts. Experiments examining shocked nitrocellulose films produced larger ion signals. The majority of the products were hydrogen ions. The ions appear to be emitted over a 1-2 microsecond period in a stochastic manner. Optical studies examining the light emitted from the shocked nitrocellulose showed a similar temporal profile. Similar experiments conducted using cellulose acetate detected very few ions or emitted photons.
