Physics of Electron Internal Transport Barrier in Toroidal Helical Plasmas

The role of zonal flows in the formation of the transport barrier in the helical plasmas is analyzed using the transport code. A set of one-dimensional transport equations is analyzed, including the effect of zonal flows. The turbulent transport coefficient is shown to be suppressed when the plasma state changes from the weak negative radial electric field to the strong positive one. This bifur...

Changes in Core Electron Temperature Fluctuations Across the Ohmic Energy Confinement Transition in Alcator C-Mod Plasmas

The first measurements of long wavelength (kyρs < 0.3) electron temperature fluctuations in Alcator C-Mod made with a new Correlation Electron Cyclotron Emission (CECE) diagnostic support a long-standing hypothesis regarding the confinement transition from Linear Ohmic Confinement (LOC) to Saturated Ohmic Confinement (SOC). Electron temperature fluctuations decrease significantly (∼40%) crossin...

Appearance and dynamics of helical flux tubes under electron cyclotron resonance heating in the core of KSTAR plasmas.

Dual (or sometimes multiple) flux tubes (DFTs) have been observed in the core of sawtoothing KSTAR tokamak plasmas with electron cyclotron resonance heating. The time evolution of the flux tubes visualized by a 2D electron cyclotron emission imaging diagnostic typically consists of four distinctive phases: (1) growth of one flux tube out of multiple small flux tubes during the initial buildup p...

Inverse Braking Radiation and Resonance Absorption in Corona Plasmas of Inertial Confinement Fusion

Abstract: In this paper, combining the Maxwell equations with the electron balanceequation, we obtain the inverse braking radiation absorption coefficient in a laser fusioncorona plasma. For a fixed plasma temperature, variations of the absorption coefficientversus the penetration depth into the plasma are illustrated numerically for differentvalues of laser wavelength. ...
