Shield design of the materials test station's camera room

The Materials Test Station (MTS) is a project funded by the Advanced Fuel Cycle Initiative with the goal to build a facility that allows large-scale irradiation for potential future nuclear fuel and material samples to obtain the knowledge and understanding of the nuclear processes necessary to close the nuclear fuel cycle and thereby reduce the amount and the toxicity of the nuclear waste. The MTS is proposed to be built in Area A of the Los Alamos Neutron Science Center and operated at up to 2 MW (2.5 mA at 800 MeV). As part of this operation, a so-called camera room will need to be installed upstream of the target cell. Because of the uniqueness of this functionality, the camera room requires a special shielding design, which will be discussed in this paper.
