DTRA’s advancements in nuclear and radiological detection
A new, more complex nuclear age has begun. Echoing the tensions of the Cold War amid rapidly evolving nuclear and radiological threats, preparedness in the modern age is a contest of scientific innovation. The Research and Development Directorate (RD) at the Defense Threat Reduction Agency (DTRA) is charged with winning this contest.

The relationships among the radial distributions of neutral beam momentum and particle sources, the radial distribution of ion orbit losses, and the resulting radial distributions of toroidal and poloidal rotation velocities and radial pressure gradients and the radial distribution of the ion and electron temperatures are derived from the requirements of particle, momentum, and energy conservation.
