Abstract : In this research program, an apparatus using electron beam, laser beam and molecular beam has been constructed to measure the electron-impact-ionization cross sections and electron-attachment cross sections of radicals that are abundant in electrical discharge media. The electron excitation cross sections of radicals are very little known. The radical data are needed for understanding the microscopic processes of electrical discharges and for designing gaseous discharge switches. High power gaseous discharge switches are currently needed for the development of inductive-energy-storage systems, high power lasers, and particle beam experiments.
