How we deploy innovation

In the mid-1990s, Los Alamos scientists were developing proton radiography techniques for a variety of applications and decided to try using muons instead of protons. Cosmic-ray muons, produced when cosmic rays strike the upper atmosphere, are subatomic particles that shower down on Earth unnoticed. The resulting technology is known as muon scattering tomography, a breakthrough variation of muon tomography.

Muons can penetrate heavy shielding and tell you precisely what is in a vehicle or container without ever having to open it up. In response to the Sept. 11, 2001 terrorist attack on the United States, the Los Alamos funded a unique project to use the multiple scattering angle of individual muons passing through an object to detect smuggled nuclear materials in cargo.

Decision Sciences has constructed and delivered Multi-Mode Passive Detection System portal monitors at various locations in the United States and the United Kingdom. Decision Sciences International Corporation signed on as a partner to commercialize the Lab’s muon technology. Decision Sciences, with investments from the U.S. Department of Homeland Security, deployed the Multi-Mode Passive Detection System for scanning cargo containers, vehicles, and rail cars. Other applications of muon imaging has been found to be effective are nuclear reactor imaging, arms treaty verification, and structural health monitoring.
