An experimental apparatus has been developed at UNR to study few-body dynamics in target atoms, molecules, and projectile ions. For example, ionization-excitation cross sections will be studied at intermediate incident projectile velocities. Projectile ions are extracted from a small accelerator, with an energy range of 20 to 150 keV. Ions then collide with gaseous atoms or molecules in a differentially pumped gas cell, and are finally collected in a Faraday cup. A grazing incidence monochromater is used to measure the EUV radiation produced by the collision event. Cross sections are derived by normalizing this data to the ion beam current. An electron gun can be mounted in the experimental chamber to provide data for calibration of the EUV monochromatic. Calibration data and preliminary cross section measurements for ionization-excitation of He by proton impact will be reported.
