Evidence of a Second Order Phase Transformation in Turbulent Fusion Plasmas

ORAL

Abstract

Turbulence physics characterized as a Ginzburg-Landau phase transformation with the tools from BCS Theory predicts a new universal constant for all turbulent systems. At SSPX, with diagnostics for: ion temperature, Ti, from a Compact Neutral Particle Analyzer; electron temperature, Te, from Profile Thomson Scattering; and electron density, ne, from CO2 laser interferometry, we can now test these predictions using the influence of variations in the SSPX helicity injection during a single shot on turbulent magnetic field fluctuations. We will report on these successful tests and their implication for the broad class of isolated turbulent fusion plasma regimes.
