General theory of kinetic ballooning modes by
Princeton University(
Book
)
4 editions published in 1979 in English and held by 61 WorldCat member libraries worldwide
The ballooning mode formalism, previously developed for the ideal MHD problem, is applied here to the kinetic problem in tokamaks. The general twodimensional equation governing drift and trappedelectron eigenmodes reduces to a onedimensional integral equation along the lines of force with the radial structure determined by a WKB procedure. Comparisons made between the present onedimensional code and a previous twodimensional code embodying identical physical assumptions indicate reasonable agreement. This correspondence holds both for the structure along the field line and for the radial structure in the special case of closely spaced turning points

A. H Boozer(
Book
)
4 editions published in 1980 in English and held by 60 WorldCat member libraries worldwide
A method for evaluating transport in nonsymmetric systems is developed and applied to a previously unstudied ripple collisionality regime of tokamaks. This collisionality regime, the ripple plateau, is the regime of primary importance both for present day and reactor scale tokamaks. The results can be directly applied to related systems like the toroidal Z pinch

Computational studies of impurity effects, impurity control, and neutral beam injection in large tokamaks by
Princeton University(
Book
)
3 editions published in 1978 in English and held by 58 WorldCat member libraries worldwide
Computational models have been constructed for the Princeton Large Torus (PLT), the Poloidal Divertor Experiment (PDX), and the Tokamak Fusion Test Reactor (TFTR). These models have been calibrated by comparison with current experiments and used to predict plasma parameters and delineate favorable modes of operation for future experiments. The models for PLT emphasize plasma transport and neutral beam injection heating. The models for PDX emphasize the capability of divertors for impurity and recycling control in intense neutralbeamheated tokamaks, as well as optimization of the MHD properties of divertorequipped tokamaks. The TFTR calculations stress the fusion aspects of a large, circular crosssection DT tokamak with intense neutral beam injection

Unstable universal drift eigenmodes in toroidal plasmas by
C. Z Cheng(
Book
)
4 editions published in 1979 in English and held by 58 WorldCat member libraries worldwide
The eigenmode equation describing ballooning collisionless drift instabilities is analyzed both analytically and numerically. A new branch of eigenmodes, which corresponds to quasibound states due to the finite toroidicity, is shown to be destabilized by electron Landau damping for typical Tokamak parameters. This branch cannot be understood by the strong coupling approximation. However, the slablike (PearlsteinBerk type) branch is found to remain stable and experience enhanced shear damping due to finite toroidicity

Observations of giant recombination edges on PLT tokamak induced by particle transport by
Princeton University(
Book
)
3 editions published in 1980 in English and held by 58 WorldCat member libraries worldwide
Characteristic steps in the continum spectrum of high temperature tokamak plasmas associated with recombination radiation from impurity ions were observed. During special argonseeded discharges on the Princeton Large Torus (PLT) tokamak the xray spectrum exhibited large enhancements over the bremsstrahlung continuum beginning with energies of 4.1 keV. This corresponds to the radiative capture of free electrons by hydrogenlike argon into the ground state of heliumlike argon. A simple particle diffusion model is proposed, with the Ar XVIII radial profiles evaluated from the size of the recombination edges. For the case of moderate density (<n/sub e/> approx. 3 x 10¹³ cm⁻³) and temperature (T/sub e/(0) approx. 1.5 keV) discharges the outward radial transport velocity is found to be approximately 10 m/sec

Observations of several disruptions in PLT using soft and ultrasoft xray radiation by
Princeton University(
Book
)
3 editions published in 1979 in English and held by 58 WorldCat member libraries worldwide
The evolution of ultrasoft xray radiation (USX, h.nu. approx.> 100 eV) is compared to that of the soft xray radiation (SX, h.nu. approx.> 1000 eV) during several disruptions in PLT. Spatial resolution is obtained in both cases by arrays of silicon surface barrier detectors viewing along different chords. During some disruptions the USX behaves quite differently from the SX, and a classification is made based on the USX behavior. Different interpretations of the data are discussed, along with the possibility that these measurements may distinguish between the roles of temperature and impurity density changes during disruptions

Plasma heating by externally launched ion Bernstein waves by
M Ono(
Book
)
3 editions published in 1979 in English and held by 58 WorldCat member libraries worldwide
Externally launched ion Bernstein waves are shown to provide highly effective means for heating reactor plasmas. In a high density plasma (n₀ greater than or equal to 10¹⁴cm⁻³), an ion Bernstein wave with a parallel index of refraction n/sub parallel/ = O (1) is modetransformed into a highdensity ion Bernstein wave with electron Landau damping several orders of magnitude smaller than that of the original ion Bernstein wave. Because of this reduced damping, an externally launched ion Bernstein wave with n/sub parallel/ less than or equal to 6 can penetrate to and deposit most of its wave power in the core of even a reactorgrade plasma (n₀= 3 x 10¹⁴cm⁻³, T/sub eo/ = T/sub io/ = 7 keV, B₀ = 60 kG)

Particle diffusion by magnetic perturbations of axisymmetric geometries by
Harry E Mynick(
Book

3 editions published in 1979 in English and held by 58 WorldCat member libraries worldwide
The quasilinear theory of collisionless test particle diffusion in stochastic magnetic fields is extended to include the effects of finite gyroradius, particle drifts, and magnetic trapping. Runaway confinement is substantially improved relative to earlier estimates which assumed that particles exactly followed field lines. Trapped particles are not expected to be stochastic

Effect of convective loss on the parametric decay of cold electron plasma waves by
Ka Leung Wong(
Book
)
3 editions published in 1979 in English and held by 58 WorldCat member libraries worldwide
The resonant decay of cold electron plasma waves was investigated in the Princeton L3 device in an argon plasma with n approx. 10¹°⁻⁻¹°sup 11/ cm⁻³, B approx. 700 G 2kG, f₀ approx. 50 to 80 MHz (omega₀ greater than or equal to 10 omega/sub LH/). The decay waves were identified to be ionacoustic waves and cold electron plasma waves. Because of convective losses in the finite extent pump field, the threshold for parametric decay is considerably higher than the collisional threshold for the dominant anti E/sub 0 perpendicular/ x anti B coupling. Coupling due to E/sub 0''/ can be important in low density high magentic field plasmas. At high densities (n> 3 x 10¹°cm⁻³), anti E/sub 0 perpendicular/ x anti B coupling becomes dominant. The anti E/sub 0 perpendicular/ x anti B decay convective threshold was measured at various antenna lengths; magentic field strengths and plasma densities

Conditions for soft Xray lasing action in a confined plasma column by
S Suckewer(
Book
)
3 editions published in 1979 in English and held by 58 WorldCat member libraries worldwide
The idea of using a multiZ (e.g., carbon, oxygen) thin plasma column as a medium for soft xray lasing action is presented. A plasma confined by a strong magnetic field is first heated by a CO₂laser, and then cools rapidly by radiation losses. This leads to a level population inversion of hydrogenlike carbon or oxygen ions. Two computational models are presented. One uses given electron temperature, T/sub e/(t), evolutions. The other uses T/sub e/(t) calculated from an energy balance equation ith CO₂laser beam power as a parameter. According to calculations, a total gain of G> 100 is expected for 3 .>. 2 and G> 10 for 4 .>. 2 transitions (lambda = 182 A and lambda = 135 A, respectively) for CVI ions using a CO₂laser beam with power approx. 5 x 10¹° W for plasma column heating

Strong minority proton heating is produced in PLT through ion cyclotron resonance damping of fast waves at moderate rf power levels. In addition to demonstrating good proton confinement, the proton energy distribution is consistent with FokkerPlanck theory which provides the prescription for extrapolation of this heating regime to higher rf power levels
