A Los Alamos design study for a high-power spallation-neutron-source driver

A design study for an accelerator-driven spallation-neutron source is underway at Los Alamos. The driver, based on the LAMPF facility, produces a 1-MW proton beam and is upgradable to 5 MW. After linear acceleration to full energy, an H/sup -/ beam is accumulated for approximately 1.2 ms in an accumulator ring and then extracted to produce an intense proton burst, less than 1 /spl mu/s long, onto a spallation-target system with a 60-Hz pulse rate. The design uses existing infrastructure insofar as possible while maintaining project goals. This paper summarizes the system specifications and design status.<
