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

摘要

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-beam is accumulated for approximately I ms in a compressor ring and then extracted to produce an intense proton burst, less than 1 (mu)s long, onto a spallation target system with a 60-Hz cycle rate. The design uses existing infrastructure insofar as possible while maintaining project goals. This paper summarizes the system specifications and design status.
