Particle diffusion by magnetic perturbations of axisymmetric geometries by
Harry E Mynick(
Book
)
4 editions published in 1979 in English and held by 64 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

By utilizing a singly phased external ring structure, the existence of the cold low frequency resonance cone is verified for .omega. <.cap omega./sub i/ and .omega./k/sub parallel parallel/> V/sub Te/. Then with a slow wave structure, the dispersion relations of the cold electrostatic ion cyclotron waves are measured in both single and twoionspecies plasmas. In a twoionspecies plasma, a resonance near the ionion hybrid frequency is observed

Plasma heating by externally launched ion Bernstein waves by
M Ono(
Book
)
3 editions published in 1979 in English and held by 62 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)

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 62 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

Suppression of lower hybrid wave coupling due to the ponderomotive force by J. R Wilson(
Book
)
3 editions published in 1980 in English and held by 62 WorldCat member libraries worldwide
The coupling efficiency from a slowwave structure to lower hybrid waves is investigated experimentally. At moderate electric field strengths large edge density changes are observed. Wave trajectory modifications and departure from linear coupling are observed consistent with these changes and in good agreement with a simple nonlinear theory that includes the ponderomotive force

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 62 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

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 62 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

An algorithm for locating the extremum of a multidimensional constrained function and its application to the PPPL hybrid
study by
C Bathke(
Book
)
4 editions published in 1978 in English and held by 62 WorldCat member libraries worldwide
A description is presented of a general algorithm for locating the extremum of a multidimensional constrained function. The algorithm employs a series of techniques dominated by random shrinkage, steepest descent, and adaptive creeping. A discussion follows of the algorithm's application to a ''real world'' problem, namely the optimization of the price of electricity, P/sub eh/, from a hybrid fusionfission reactor. Upon the basis of comparisons with other optimization schemes of a survey nature, the algorithm is concluded to yield a good approximation to the location of a function's optimum

Enhanced transport in tokamaks due to toroidal ripple by A. H Boozer(
Book
)
4 editions published in 1980 in English and held by 62 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

A general theory for particle acceleration by weak hydromagnetic turbulence with a given spectrum of waves is described. Various limiting cases, corresponding to Fermi acceleration and magnetic pumping, are discussed and two numerical examples illustrating them are given. An attempt is made to show that the expression for the rate of Fermi acceleration is valid for finite amplitudes

Analytical theory of drift waves and drift Alfvén waves in tokamaks by
C. Z Cheng(
Book
)
4 editions published between 1979 and 1980 in English and held by 5 WorldCat member libraries worldwide
Employing the ballooningmode formalism, the twodimensional eigenmode equation for trappedelectron instabilities in tokamaks is reduced to a onedimensional integrodifferential equation along the magnetic field lines; which is then analyzed both analytically and numerically. Dominant toroidal coupling effects are due to ion magnetic drifts which create quasibounded states. The trappedelectron response can be treated as perturbation and is found to destablize the quasibounded states
