ANL's planned Accelerator Development Facility (ADF) for heavy-ion fusion will test and demonstrate virtually all of the beam manipulations thought to be necessary for a heavy-ion inertial confinement fusion driver. The relatively simple upgrade of adding synchrotron acceleration capability to the storage ring would also allow important energy deposition and materials experiments. The feasibility of this upgrade depends critically on the beam loss rate from charge exchange scattering. A computer progran has been written for the purpose of obtaining a better estimate for this lifetime. The code assumes a K-V transverse distribution folded into a Neuffer longitudinal distribution. The emittance ellipse parameters, along with various estimates for the velocity-dependent ion-ion cross sections, are read in and a numerical integration is performed over the distribution, yielding a value for the loss rate -1/ N2 dN/ dt. Preliminary estimates indicate that this mode of beam loss presents no obstacle to upgrading the ADF.
