NSTX Science and Spherical Torus Path to Fusion Power
PPT Slide
The Science of NSTX
A Spherical Torus Fusion Research Community is Growing
START (Small Tight Aspect Ratio Tokamak) and Research Team
START Reached New Record (~40%) in Average Toroidal bt in Well-Confined NBI Plasma (1/98)
Spherical Torus Maximizes the Stable Field Line Length over the Unstable Field Line
MHD Stable, High Beta (bt = 40%) Plasmas in NSTX Are Calculated
Very High Flow Shearing Rate is Anticipated in NSTX
Nearly Self-Driven (BS) Currents at High b Are Also Calculated, Well Aligned with Total Current
NSTX Plasma Exhaust Channel Has Expanded Area of Contact with Material Wall
HIT Demonstrated the Feasibility of Coaxial Helicity Injection Startup (Courtesy of HIT Team)
