The Tokamak Fusion Test Reactor (TFTR) (R. J. Hawryluk, to be published in Rev. Mod. Phys.) experiments on high-temperature plasmas, that culminated the study of deuterium–tritium D–T plasmas containing significant populations energetic alpha particles, spanned over two decades from conception completion. During design TFTR, key physics issues were magnetohydrodynamic (MHD) equilibrium and stability, plasma energy transport, impurity effects, reactivity. Energetic particle was given less...
A new procedure for calculating the nonlinear energy transfer and linear growth/damping rate of fully developed turbulence is derived. It avoids unphysically large damping rates typically obtained using predecessor method Ritz [Ch. P. Ritz, E. J. Powers, R. D. Bengtson, Phys. Fluids B 1, 153 (1989)]. enforces stationarity to reduce effects noise fluctuations not described by basic governing equation, includes fourth-order moment avoid closure approximation. The has been implemented tested on...
A localized transition zone is observed between turbulent, long-wavelength density fluctuations (${\mathit{k}}_{\mathrm{\ensuremath{\perp}}}$2 ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}1}$) in the core and edge of beam-heated discharges TFTR. The turbulence unimodal while has two counterpropagating modes, both which are spectrally distinct from fluctuations. fluctuation amplitude scales with global energy confinement time it does not. These observations suggest that modes responsible for...
The application of a new bispectral analysis technique to density fluctuation measurements in the core Tokamak Fusion Test Reactor indicates that peak autopower spectrum usually lies region linear stability. Large changes and nonlinear characteristics turbulence are observed as plasma toroidal rotation and/or confinement properties varied, while estimates turbulence-driven diffusivity varies only slightly with rotation. These observations consistent operation global organizing property may...
This paper examines the theological foundations in Grotius’ works, On Satisfaction of Christ against Faustus Socinus and The Rights War Peace, highlighting links between atonement other forms human sacrifice. It suggests that distinct changes regarding sacrifice observed argument across his works can largely be attributed to political development Dutch controversies. In Grotius takes a ‘secular turn’, creating distinction divine punishment while also differentiating innocent. revision...
A compact, portable, eight-channel, filter spectrometer has been designed for beam emission spectroscopy measurements of long-wavelength density fluctuations on TEXT-U and Phaedrus-T. The system uses radially elongated image volumes which maximize the étendue while still resolving dominant (kr<2 cm−1, kθ<6 cm−1). Because vertical injection geometry diagnostic neutral beam, there is little Doppler shift emissions thus a nonhydrogenic species must be used to distinguish between...
