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 Doublet III tokamak facility is presently undergoing an upgrade to Big Dee, a device projected to be capable of producing plasmas with parameters approaching breakeven conditions, albeit in hydrogen plasmas. The goal of the upgrade has been to develop a facility capable of studying confinement and beta in non-circular discharges at parameters near breakeven conditions while maintaining the flexibility and accessibility necessary to allow a wide range of problems to be addressed. The upgrade replaces the vacuum vessel and outermost plasma shaping coils allowing higher plasma currents and improved access.
