Feasibility Study of Using an Electron Beam for Profile Measurements in the SNS Accumulator Ring

The electron beam probe method was suggested for measuring profiles in high power beams. In this method, deflection of a low energy electron beam by the collective field of the high intensity beam is measured. The charge density in the high intensity beam can be restored under certain conditions or estimated by various mathematical techniques. We studied the feasibility of using the electron beam probe for the SNS accumulator ring using computer simulations of the diagnostic setup. Realistic proton beam distributions were used in the simulations. Several profile calculation techniques were explored and the results are reported in this paper.
