In order to study the microscopic physics underlying observed L-mode current scaling, 1-1/2-d BALDUR has been used to simulate density and temperature profiles for high and low current, neutral beam heated discharges on TFTR with several semi-empirical, theoretically-based models previously compared for TFTR, including several versions of trapped electron drift wave driven transport. Experiments at TFTR, JET and D3-D show that I{sub p} scaling of {tau}{sub E} does not arise from edge modes as…

Effect of the neutral beam fuelling profile on fusion power, confinement and stability in TFTR
The stored energy and neutron yields of TFTR plasmas have been modelled, with small dispersion, by considering a parameter associated with the peakedness of the beam fuelling profile as an
Self-consistent plasma modelling by Monte Carlo test particles
The question addressed in this paper is whether it is possible to model in a fully self-consistent way a thermal plasma ion population by a finite number of test particles of a Monte Carlo model.
Confidence contours for calibration of a theoretical transport model against a multitokamak database
A systematic statistical model has been used to calibrate the turbulence saturation coefficients in a theory based tokamak transport model. Confidence contours are used to assess the accuracy of

Correlations of heat and momentum transport in the TFTR tokamak
Measurements of the toroidal rotation speed vφ(r) driven by neutral beam injection in tokamak plasmas and, in particular, simultaneous profile measurements of vφ, Ti, Te, and ne, have provided new

Simple models for the dissipative trapped electron, circulating electron and toroidal ion temperature gradient drift modes, together with the effect of low-m tearing mode islands, are incorporated
Tokamak transport in the presence of multiple mechanisms
Some success has been achieved by F.W. Perkins, W.M. Tang, R.E. Waltz, A. Rogister and others in explaining tokamak transport using drift wave turbulence as the source of the losses in the
Current ramp experiments on the scaling of energy confinement
The dependence of global and local confinement upon plasma current and poloidal field is studied in an analysis of JET data from a series of current ramp experiments. In such experiments the current
H-Mode energy confinement scaling from the DIII-D and JET tokamaks
Neutral beam heated H-mode DIII-D and JET expanded boundary divertor discharges were examined to study the parametric dependence of the thermal energy confinement on the plasma current, plasma size
Microinstability-based model for anomalous thermal confinement in tokamaks
This paper deals with the formulation of microinstability-based thermal transport coefficients (chi/sub j/) for the purpose of modelling anomalous energy confinement properties in tokamak plasmas.
Experimental evidence for ion pressure gradient driven turbulence in text
For high density Ohmic discharges in the TEXT tokamak, a distinct ion mode (i.e. density fluctuations propagating in the ion diamagnetic drift direction) is observed in the microturbulence spectra.
