MODELING OF COUPLED EDGE STOCHASTIC AND CORE RESONANT MAGNETIC FIELD EFFECTS IN DIVERTED TOKAMAKS [PDF]

, 2002
Attaining the highest performance in poloidally diverted tokamaks requires resonant magnetic perturbation coils to avoid core instabilities (locked, resistive wall and neoclassical tearing modes).

Experimental investigation of ELM-like transient heat loads on plasma-facing materials using runaway electrons

Nuclear Materials and Energy
Edge-localized modes (ELMs) and runaway electrons (REs) are among the most critical transient heat sources responsible for degradation of plasma-facing materials (PFMs) in tokamaks. Small-scale tokamaks, such as Damavand, provide a practical platform for

Reversal of the isotopic dependence of energy confinement in system size scans

Nuclear Fusion
We report a reversal in the isotopic dependence of energy confinement with increasing system size $\rho^{\ast-1}$ from electrostatic global δ f gyrokinetic simulations.

Balancing physics priors and data for disruption prediction in future tokamaks

Nuclear Fusion
Disruption remains a major barrier to the safe, sustained operation of tokamaks. Although current understanding of disruption physics is broadly valid across existing tokamaks, it cannot provide accurate disruption prediction rules.

Stellarators with enhanced tritium confinement and edge radiation control

Nuclear Fusion
A stellarator design is described with the purpose of achieving three goals: (1) enhance the confinement time of tritium. (2) Have a sufficient density of high- Z impurities to radiate the thermal power escaping from the core while having an extremely ...

Neutral beam injector performance on the PLT and PDX tokamaks [PDF]

, 1981
An overall injector system description is presented first, and this will be followed by a detailed discussion of those problems unique to multiple injector operation on the tokamaks, i.e., power transmission, conditioning, reliability, and ...
