The objective of this program is to develop theories and computational methods which describe the fundamental parameters and processes necessary to understand the interaction of intense, short pulse charged particle beams with molecules, atoms, ions, and plasmas including collisional excitation, ionization, dissociation, recombination, and de-excitation processes. The overall goals of the project include description of the transition of intense charged particle beam driven plasmas from weakly-ionized and molecular to strongly-ionized and atomic. This includes determination of scattering cross sections for step-wise processes to ionization and dissociation as well as predicting the production rate of characteristic line radiation from air species. Of particular interest is evaluation of electron scattering cross section data and characterization of uncertainty in the data including covariance.
