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.

This report summarizes the results of experimental investigations on the Gas Dynamic Trap (GDT) obtained during the last five years. Due to essential upgrade of the GDT facility performed during this period, the following plasma parameters were obtained: electron temperature-90-110 eV, fast ion density (mean energy — 5–8 keV) — up to 0.8×1013cm−3, plasma β — 15–20%. The following experiments are described: study of the effect of the wall conditioning on neutral gas transport, detailed investigations of the longitudinal electron heat flux, study of confinement of the high β two-component plasma, detailed study of fast ion parameters in experiments with high β, investigations of fueling of the bulk plasma by gas puffing. The results of the experiments to be described:
