A unique feature of the current LANSCE accelerator facility is acceleration of four H- beams (differing in time structure) and one H+ beam. This is achieved by utilization of an injector system based on two ion sources (H+/H-), and a combination of chopper and RF bunchers in the Low Energy Beam Transports. Since the end of 1990’s, the large LANSCE experimental, Area-A, has been largely unused. In order to restore usage of Area-A, we have been exploring the possibilities of bringing low-intensity power beams into Area-A*. The proposal is based on partial stripping of the 800 MeV H- beam that is transported to the Weapons Neutron Research Facility, and to deliver the resulting 10 – 100 nA proton beam to Area-A. The appropriate place for generating proton beam was found to be the beginning of Line D after LANSCE Switchyard by first neutralizing the beam from H- to neutral hydrogen beam ahead of the bending magnet using a laser, and then by fully stripping the neutral hydrogen beam to protons utilizing a stripper foil. The paper discusses design details of the proposed high-energy beamline and beam parameters.
