X-rays and gamma rays have a wide range of applications including scanning suspicious maritime shipping containers for illicit materials, industrial inspection of materials and processes, and medical diagnostic and therapeutic procedures. Current technologies, however, are not ideal. X-rays produce a continuum of energies that limit their inspection and diagnostic performance, and gamma rays can only be produced at specific energies unique to a given radioactive isotope.

The Defense Advanced Research Projects Agency (DARPA) Defense Sciences Office (DSO) is sponsoring a Proposers Day webcast to provide information to potential proposers on the objectives of an anticipated Broad Agency Announcement (BAA) for the Gamma Ray Inspection Technology (GRIT) program.
The Gamma Ray Inspection Technology (GRIT) program seeks transformational approaches to achieving high-intensity, tunable, and narrow-bandwidth gamma ray production, but in a compact form factor suitable for transporting the source to where the capability is needed.
Coherent, short-wavelength UV light is useful for a range of applications such as decontamination, precision manufacturing, real-time medical diagnostics, and chemical and biological identification using Raman spectroscopy. However, many applications are unable to transfer out of the lab because the UV lasers needed to generate these coherent photons are prohibitively large, complicated and expensive.

The Gamma Ray Inspection Technology (GRIT) program seeks transformational approaches to achieving high intensity, tunable, and narrow-bandwidth gamma-ray production, in a compact form factor suitable for transporting the source to where the capability is needed. Such sources have the potential to help discover smuggled nuclear materials in cargo, provide new non-destructive inspection techniques at various scales, and enable new medical diagnostics and therapies.
