Shielding maze design for Line C tunnel at LANSCE - 25456

The Los Alamos Neutron Science Center (LANSCE) is a major experimental facility at Los Alamos National Laboratory. The LANSCE linear accelerator (linac) supplies proton beams to five experimental areas simultaneously. The Isotope Production Facility (IPF) utilizes a 100-MeV beam after the first stage of acceleration, all other facilities use proton beams at 800 MeV. However, the facility can support sole-use experiments at 200-600 MeV proton beam energies. There are three spallation neutron sources providing neutrons in different energy regimes: Weapons Neutron Research (WNR), Lujan Neutron Scattering Center (Lujan Center) and the Ultra Cold Neutron source (UCN). The proton radiography (pRAD) facility utilizes the energetic proton beam for imaging and tomography directly. The beam to pRAD and UCN facilities is delivered via line X that splits into line C (pRAD) and line B (UCN). Due to engineering access controls it is impossible to deliver beam to UCN while the pRAD facility is occupied. The goal of our project was to design a shielding maze arrangement for line C to allow for simultaneous beam delivery to UCN while pRAD area (dome) is occupied. (authors)
