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.

Applying a voltage on the rectangular metal plate in RF produced plasma, two-dimensional profiles of ion saturation current, transverse plasma flow and floating potential were measured, changing a filling pressure, magnetic field and applied voltage. It was found that near the plate surface, plasma density was lower and the spatial inhomogeneity of shifted profile was enhanced, which was consistent with the Mach probe measurement and E × B direction (E: electrostatic field, B: magnetic field).
