Density limits in toroidal plasmas
In addition to the operational limits imposed by MHD stability on plasma current and pressure, an independent limit on plasma density is observed in confined toroidal plasmas. This review attempts to summarize recent work on the phenomenology and physics of the density limit. Perhaps the most surprising result is that all of the toroidal confinement devices considered operate in similar ranges ...
متن کاملSelf Consistent Calculations of Ion Cyclotron Resonance Heating in Toroidal Plasmas
A method for self consistent calculations of ion cyclotron resonance heating has been developed. The dielectric tensor is calculated from a particle distribution function calculated with the orbit averaged Monte Carlo code fido. The tensor is then fed into the global wave code lion. The calculated wave field and power partitions are fed back into the fido code. By using two existing codes in an...
متن کاملA Global Simulation Study of ICRF Heating by TASK/WM and GNET in Toroidal Plasmas
A global simulation code is developed to study the ICRF heating combining two global simulation codes: a full wave field solver, TASK/WM, and a drift kinetic equation solver, GNET. The both codes can treat a 3-D magnetic configuration based on the MHD equilibrium by VMEC code. The developed code is applied to the ICRF minority heating in a simple circular tokamak. The ICRF wave propagation is s...
متن کاملNeoclassical Transport in Enhanced Confinement Toroidal Plasmas
It has recently been reported that ion thermal transport levels in enhanced confinement tokamak plasmas have been observed to fall below the "irreducible minimum level" predicted by standard neoclassical theory. This apparent contradiction is resolved in the present analysis by relaxing the basic neoclassical assumption that the ions orbital excursions are much smaller than the local toroidal m...
متن کاملPaleoclassical transport in low-collisionality toroidal plasmas
Radial electron heat transport in a low-collisionality, current-carrying resistive plasma confined in an axisymmetric toroidal magnetic field is hypothesized to be caused by the paleoclassical collisional processes of parallel electron heat conduction and radial magnetic-field diffusion. The electron distribution is Maxwellianized and the electron temperature equilibrated over a long length L t...
