A next-generation signature facility based on multi-probe capabilities is being planned at Los Alamos. This new facility will enable the first in a new generation of game-changing scientific facilities for the materials community. The new Matter-Radiation Interactions in Extremes (MaRIE) facility will be used to discover and design the advanced materials needed to meet 21st-century national security and energy-security challenges to develop next-generation materials that will perform predictably in extreme environments. The MaRIE facility will include a new 12-GeV electron linac using a state-of-the-art electron photoinjector and superconducting accelerator technology to drive a 42-keV XFEL to generate x rays of unprecedented flux and quality, coupled with the existing proton-beam capabilities of the LANSCE proton linac, new experimental halls, and new materials fabrication/characterization facilities. A description of this new facility, its requirements, and planned uses and capabilities will be presented. Status of the project will also be presented.

Muons have been demonstrated to be great probes for imaging large and dense objects due to their excellent penetrating ability. At present there are no muon accelerators. Development of a compact system that can produce an intense beam of accelerated muons would provide unique imaging options for stockpile stewardship while delivering minimal radiation dose, as well as various homeland-security and industrial applications. Our novel compact accelerator approach allows a single linac to be used to first accelerate an electron beam to 800 MeV to generate muons by interacting with a production target in a high-field solenoid magnet and then to collect and accelerate these low-energy muons to 1 GeV to be used for imaging or active interrogation. The key enabling technology is a high-gradient accelerator with large energy and angular acceptances. Our proposed solution for efficient acceleration of low-energy muons is a 0-mode linac coupled with conventional electron RF accelerating structures to provide a compact system that could deliver a controllable high-flux beam of muons with well-defined energy to allow precise radiographic inspections of complicated objects. The details of the conceptual design will be discussed.
