Abstract

The results of investigation and comparison of a series of transverse phase space painting schemes for the injection of the SNS accumulator ring is reported. In this computer simulation study, the focus is on the creation of closed orbit bumps that give desired distributions at the target. Space charge effects such as tune shift, emittance growth and beam losses are considered. The results of pseudo end-to-end simulations from the injection to the target through the accumulator ring and the Ring to Target Beam Transfer (RTBT) system are presented and discussed
