A new predictive computer simulation tool targeting the development of the H-mode pedestal at the plasma edge in tokamaks and the triggering and dynamics of edge localized modes (ELMs) is presented in this report. This tool brings together, in a coordinated and effective manner, several first-principles physics simulation codes, stability analysis packages,(More)
The NUBEAM module is a comprehensive computational model for Neutral Beam Injection (NBI) in tokamaks. It is used to compute power deposition, driven current, momentum transfer, fueling, and other profiles in tokamak plasmas due to NBI. NUBEAM computes the time-dependent deposition and slowing down of the fast ions produced by NBI, taking into consideration(More)
discharges are carried out for the 15 MA high confinement mode ͑H-mode͒ scenario using PTRANSP, the predictive version of the TRANSP code. The thermal and toroidal momentum transport equations are evolved using turbulent and neoclassical transport models. A predictive model is used to compute the temperature and width of the H-mode pedestal. The ITER(More)
In solving the 1D (flux surface averaged) transport equations for the temperatures, magnetic fields, and densities in the ''evolving equilibrium " description of a tokamak [1], one increasingly encounters highly nonlinear thermal conductivity and diffusivity functions, such as GLF23 [2], that have a strong and non-analytic dependence on the temperature(More)
COMPACT IGNITION TOKAMAK PHYSICS AND ENGINEERING BASIS. The Compact Ignition Tokamak (CIT) is a high-Beld, compact tokamak design whose objective is the study of physics issues associated with burning plasmas. The toroidal and poloidal field coils employ a copper-steel laminate, mamrfacmred by explosive-bonding techniques, to support the forces generated by(More)
A model is proposed for the edge electron temperature profile Te(ρ) in high (H) confinement mode, diverted tokamak plasmas based on the paleoclassical model for the minimum radial electron heat transport. Moving inward from the separatrix, Te profile predictions are: first an increasing Te gradient with ηe ≡ d ln Te/d ln ne 2, a maximum |∇Te| where q drops(More)
