Abstract

The SNS ring and associated transport lines, commissioned in January 2006, are designed to accumulate and deliver up to 1.5e14, 1 GeV protons at 60 Hz to a liquid mercury target for neutron production. In order to control activation and to allow for routine hands-on maintenance of accelerator components, beam loss in most of the ring must remain below 1 W/m. For the full 1.4 MW beam, this translates to a fractional beam loss limit of 0.02%. Accomplishing this loss limit at full beam power will require successful utilization of the ring's two-stage betatron collimation system. In this paper we present the results of initial collimation experiments. We characterize the collimation-induced beam-loss pattern and compare our results with simulations.
