Title Conceptual design of DIII-D experiments to diagnose the lifetime of spin polarized fuel
Abstract In magnetic fusion experiments, the cross sections for the D-T and D- 3He fusion reactions are increased by as much as 50% if the fuel remains spin polarized parallel to the magnetic field. The goal of this study is to assess the feasibility of lifetime measurements of spin polarization, in magnetic fusion relevant conditions, on the DIII-D tokamak using relative changes in charged fusion product (CFP) loss measurements that depend upon the differential fusion cross section d?/d?. Relative measurements that capture changes in the escaping CFP pitch, poloidal, and energy distributions are studied in two realistic TRANSP calculated plasma scenarios: 1) vector-polarized 3He and D pellets are injected into a hot hydrogen plasma to produce thermonuclear reactions, and 2) a tensor-polarized deuterium pellet is injected into an L-mode hydrogen background plasma that includes unpolarized 3He neutral beam injection (NBI). Ideal CFP signals in both scenarios show substantial pitch sensitivity to
