Abstract

The limitation in increasing the beam current in the SLC linac comes from the emittance growth caused by wakefields. Simulations of the beam transport that model the wakefield dynamics are being done to study methods to control this growth. To verify the theoretical estimates of the wakefield strengths assumed in these simulations, data were taken which are sensitive to their effect on the first-order linac transport. Specifically, the dependence of single beam loading and betatron motion on beam current was measured in the range of 0.5*10/sup 10/ to 3.5*10/sup 10/ electrons per bunch. These data are presented along with comparisons to results from simulations.<>
