Impact Analysis of Hall Thrusters on Satellite Antenna Performance
Autor: J. C. Wiley, J. William Meyer, Ashish Khanna, Edmund Spencer, Gary A Hallock, Joseph T. Loane
Publikováno v: Journal of Spacecraft and Rockets. 39:115-124
A geometrical optics ray-tracing code has been developed to study the effect of plasma thrusters on communication satellite antennas. This code has e exible three-dimensional geometry and a friendly web-based interface. A study is reported where a th

The role of rotation in tokamak internal transport barriers
Autor: R. E. Waltz, G. M. Staebler, J. C. Wiley
Publikováno v: Nuclear Fusion. 37:287-291
Internal transport barriers have been observed in several tokamak operating regimes and the reduced transport has been shown to be qualitatively consistent with E*B rotational shear suppression of turbulence. The interaction of the toroidal rotation

Designing a VH-mode core/L-mode edge discharge
Autor: F L Hinton, J. C. Wiley, G. M. Staebler
Publikováno v: Plasma Physics and Controlled Fusion. 38:1461-1464
An operating mode with a very high confinement core like the VH-mode but a very low power flow to the divertor plates and low edge particle confinement like an L-mode would be beneficial. For a large tokamak like the proposed ITER, the power density

High and very high modes from energy, particle, and momentum transport models
Autor: G. M. Staebler, R. R. Dominguez, T.H. Osborne, P. Gohil, C. M. Greenfield, F.L. Hinton, J. C. Wiley, T. K. Kurki‐Suonio
Publikováno v: Physics of Plasmas. 1:909-926
Time‐dependent simulations of energy, particle, and momentum transport are presented, which show improved confinement similar to the high mode (H mode). The transport model incorporates the suppression of turbulence by sheared flows, which are self

The electrostatic wake of a superthermal test electron in a magnetized plasma
Autor: J. C. Wiley, A. A. Ware
Publikováno v: Physics of Fluids B: Plasma Physics. 5:2764-2768
The electrostatic potential is determined for a test electron with v∥ ≫ vTe in a uniform magnetized plasma (ωce ≫ ωpe). In the frame of the test electron, part of the spatially oscillatory potential has spherical symmetry over the hemisphere

Publikováno v: Nuclear Fusion. 32:567-579
The authors presents a plasma density perturbation analysis which closely couples measurements of perturbations in density, temperature and turbulent fluctuation levels with a theoretical model in order to calculate particle fluxes. Non-linearities i

Modeling transport in toroidal plasmas: Status and issues
Autor: P. C. Efthimion, W. W. Pfeiffer, W. A. Houlberg, David W. Ross, D. E. Shumaker, L. E. Sugiyama, G. D. Porter, Steven Cowley, J. C. Wiley, G. Bateman
Publikováno v: Physics of Fluids B: Plasma Physics. 2:2913-2925
The scope and detail of physics contained in computational models for fluid (density, momentum, energy) transport in toroidal plasmas have steadily increased during the past two decades. There has been considerable success in the development and veri

Validation of the geometric optics approximation for microwave antenna analysis with an inhomogencous plasma plume
Autor: J. C. Wiley, Alexandra A. García, Gary A Hallock
Publikováno v: The 31st IEEE International Conference on Plasma Science, 2004. ICOPS 2004. IEEE Conference Record - Abstracts..
Summary form only given. The Hall thruster is the most appropriate candidate to replace chemical propulsion systems on geosynchronous communications satellites. This thruster expels an inhomogenous plasma plume for long periods of time, which can cro
