Abstract :
The high intensity stored beam stability limits of the IUCF (Indiana University Cyclotron Facility) cooler-storage ring are being explored. Measurements of the equilibrium emittance and bunching factor for a 45 MeV electron cooled proton beam as a function of stored beam intensity are reported. In addition, calculations of space-charge tune shift based on these measurements are presented. The tune shift is found to be as large as about 0.3 in magnitude, depending on the degree to which the beam is cooled. The space-charge tune shift is discussed as a possible contributing factor to observed stored beam current limits.<>
