Computation of intrabeam charge-exchange rate

Description

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 program 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 ... continued below

Description

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 program 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/N/sup 2/ dN/dt. Preliminary estimates indicate that this mode of beam loss presents no obstacle to upgrading the ADF.
