Neutral Beam Injection construction and modelling on WHAM

The Wisconsin HTS Axisymmetric Mirror (WHAM) will utilize advances in high temperature superconductors and recent physics developments to explore the feasibility of axisymmetric magnetic mirrors as a fusion power-plant. WHAM will use neutral beam injection (NBI) for a variety of functions including plasma heating, sloshing ion population creation and warm plasma trapping. We present the current status of the neutral beam heating system and a path to full power operations (1MW at 25keV), diagnostic development to resolve the spatial fusion reactivity profile via a proton detector array and an end loss energy analyzer to resolve the radial electron and ion temperature profiles via measurements made in the end cells. Modelling via CQL3D analyzes the effect of background density and temperature on the sloshing ion distribution. The non-thermal effects of a beam dominated plasma including in particular the Alfven Ion Cyclotron (AIC) instability are considered.
