R&D CHALLENGES AT THE SPALLATION NEUTRON SOURCE HIGH POWER ACCELERATOR

SARAH COUSINEAU, UNIVERSITY OF TENNESSEE, KNOXVILLE

The Spallation Neutron Source accelerator operates with a world record beam power of 1.4 MW. The accelerator is composed of a superconducting hadron linear accelerator to an energy of 1 GeV, and an accumulator ring that generates a 1us proton pulse with 1.5x1014 protons per pulse at 60 Hz. These parameters gives rise to a number of challenges associated with operating a very high intensity, high power accelerator. The accelerator science research program at SNS is focused on exploring the most limiting challenges to enable solutions for performance improvement and for next generation accelerators. This talk will review the status of four research thrusts in the area of high intensity beam dynamics in linear accelerators and rings, charge-exchange injection technologies, and surface processing techniques for accelerator gradient improvement in superconducting cavities.
