Proposal for a Meso-Scale Science Facility in Area A at the Los Alamos Neutron Science Center*

Experimental Area A at LANSCE is a large unused experimental area with overhead crane coverage, installed power, access to the LANSCE proton beam, and more than 30,000 square feet of floor space. In former times it was used for pion experiments. We propose to restore proton delivery to Area A and to build a new three axis proton radiography area designed to support high, peak-intensity, low-power, low-emittance beam delivery for studying small dynamic experiments aimed at studying dynamic materials physics at the meso-scale. With the addition of a responsive RF kicker currently under evaluation, such a facility could support multiple beamlines, including a multi-axis proton radiography installation. A refurbished Area A would also support other high-current experimental beamlines for materials studies and isotope production. We will present the technical options and some examples of physics opportunities where the temporal and spatial resolution offered by such a facility will help elucidate shock physics at the grain level.
