Studies of atomic processes involving keV kinetic energy multiply charged ions of importance to controlled thermonuclear fusion research have long been hampered by the lack of suitable sources of such ions. The recently available reliable sources of low energy, multiply charged ions, such as the electron beam ion source (EBIS) have changed the circumstance and make possible new and interesting experiments in atomic physics. Over the past twenty months, an EBIS capable of generating usable beams (at least 10/sup 8/ particles/sec) of C, N, and O in various stages of ionization up to and including C/sup 5 +/, N/sup 5 +/ and O/sup 6 +/, at kinetic energies ranging from 200 eV/q to 1000 eV/q has been constructed and tested at Cornell. Additional experimental apparatus has been constructed and is being used to carry out energy gain spectroscopy on triply and quadruply ionized C, N, and O ions scattered in collisions with H/sub 2/ and He in the 10 eV/q to 1000 eV/q energy range, and electron spectroscopy on electrons emitted in the decay of autoionizing states formed in two electron capture. In addition, preliminary design and cost estimate of a superconducting solenoid EBIS initially capable of generating AR/sup 18 +/ have been carried out.
