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.

We explore the utility of using a gas other than hydrogen isotopes to neutralize energetic beams of D+ or H+ for applications in magnetic confinement fusion. We find that, at D+ energies above 160 keV, helium, relative to hydrogen, offers significant improvements in neutralization efficiency and in enrichment of the full energy component of the beam, and that similar advantages accrue with neon at D+ energies in excess of 200 keV.
