The combination of a heavy-ion storage ring with the intense photon beams from a synchrotron light source present new opportunities for research in atomic physics. At Brookhaven a design for such a facility has been proposed as the basis of a comprehensive National Atomic Physics Facility. Vacuum considerations are an important factor in its performance since the storage time of the heavy ions in the ring is vacuum-dependent. A vacuum system design for attainment of pressures of order 10/sup /minus/11/ Torr in the heavy-ion ion storage ring is discussed. The photon source will be the x-ray ring of the National Synchrotron Light Source, and the heavy-ion source will be the BNL Tandem Van de Graaff Accelerators. Differential pumping between components of the facility will allow for different pressures in the ion source, accelerators, transfer lines, and storage rings. For some experiments it may be useful to have gas jet or vapor targets in experimental sections viewed by detector systems that are not suitable for use on ultrahigh vacuum systems. Possible solutions to a wide range of vacuum problems are discussed. 8 refs., 2 figs., 2 tabs.
