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 use of the compressional hydromagnetic (fast wave) mode is examined with respect to heating a minority helium-3 species in a fully catalyzed deuterium tokamak. In this paper we develop a rapid solution to analyze the two dimensional, steady state Fokker-Planck equation, with quasi-linear ICRF heating terms. This finite element solution for the minority helium-3 distribution function develops a high, anisotropic in the perpendicular velocity direction, energy tail as a result of ICRH. The rapidity of this method of solution makes it possible to conduct parametric studies which are not possible with other codes.
