The interest, both theoretical and experimental, in interactions of low energy highly charged ions with electrons, atoms or ions is due to the importance of such interactions to controlled thermonuclear fusion research and to the intrinsically interesting nature of the fundamental processes involved. Research involving low energy, very highly charged ions has long been hampered by the lack of sources capable of producing such species. In recent years, novel sources of low energy, very highly charged ions have been developed. The electron beam ion source, EBIS, is one such source which shows particular promise for use in atomic physics experiments. This research program is concerned with the development and study of the behaviour and properties of EBIS sources, and their use in atomic physics studies involving low energy, highly charged ions at keV energies. It centers around two lines of activity. One involves atomic physics experiments and source studies using a small EBIS, CEBIS I, and the other, initiated in August 1983, involves the construction of a much larger, superconducting solenoid version, CEBIS II. The immediate goal of CEBIS II is to generate a useable, approx. 3 qkeV beam of Ar/sup 18 +/. Longer range goals include optimization of the source and gradually upgrading it to handle a 25 kV, 1A electron beam which could be used to produce He-like xenon. Both sources will be used in atomic physics experiments involving low energy highly charged ions. Thus far, CEBIS I has been used to investigate low energy charge transfer to multiply charged ions, in particular, to measure partial cross sections for population of specific states of the projectile as a function of its energy for C/sup q+/, N/sup q+/ and O/sup q+/ (q greater than or equal to 3) colliding with helium in the 0.05 to 1 qkeV range. Specific states of the projectile populated in the collision are selected by high resolution energy gain spectroscopy.
