The Indiana University Cyclotron Facility (IUCF) is in the process of commissioning a new synchrotron that is designed to rapidly accumulate, accelerate and inject beam into the IUCF Cooler ring. The Cooler Injector Synchrotron (CIS) is filled by the strip injection of 7 MeV negative ions that were pre-accelerated by an RFQ-DTL linear accelerator. This pre-accelerator has an acceptance of 1.0 {pi} mm mrad normalized with an injection energy of 25 keV. The injected beam should be pulsed with a maximum repetition rate of 5 Hz, have a maximum pulse width of 300 {mu}s and a peak beam current that exceeds 300 {mu}A. Beam commissioning will be complete by the fall of 1998 at which time CIS will be used exclusively to fill the Cooler ring with both unpolarized and polarized beams. A pulsed source of polarized negative hydrogen and deuterium ions is under construction at IUCF. The source will consist of a pulsed atomic beam which is ionized by the resonant charge exchange method. Progress in the design and construction of the ABS will be described.
