Spherical Torus as an Example of Attractive Path for Fusion Energy
We would like to Solicit Comments on the Following Topics Concerning ST Pathway
U.S. Fusion Strategy Recognizes Great Potential in Advancing Fusion and Plasma Science
Great Advances in Fusion Science and Energy Technology are Targeted in the Previous Strategy
Five Development Stages of Magnetic Fusion Confinement Concept (FESAC-AltCon)
U.S. Fusion Program Needs to Examine Additional Development Pathways
How About a Paradigm Shift?
Spherical Torus Plasma Has Interesting Features of Tokamak and Spheromak Plasmas
Intriguing (and Unique) Plasma Properties of Spherical Torus Have been Suggested Recently
START Reached ~30% in Average Toroidal b in Well-Confined NBI Plasma (Gates, Sykes et al.)
An Attractive Pathway Should Require Fewer or Simpler Technology or Engineering Advances
An ST VNS Design Can Take Advantage of a Smaller and Simpler Fusion Core
This Possible Paradigm Shift is Robust to Outcomes of ITER Decisions
We Envision ST Development Path as a Good Example of Potential Benefits from Innovation
Smaller, Cheaper Devices Increase Possibility for Attractive Nearer-Term Applications
