Abstract :
The SuperHILAC (SHILAC) accelerator serves as a heavy-ion injector to the Lawrence Berkeley Laboratory´s Bevalac via a 260-m transport line. Since the acceptance and hence the final extracted beam intensity of the Bevalac is very sensitive to the emittance and dispersion of the beam at injection, a program was undertaken to accurately characterize these parameters under a variety of operating conditions. Detailed emittance results are presented. In particular, the ratios of the deconvoluted Bevalac to SHILAC emittances in the horizontal plane versus the SHILAC emittance mismatch parameter are shown
