Hydrodynamic Confinement of Thermonuclear Plasmas Trisops VIII (Plasma Liner Confinement)

Fusion Technology, 1986
Experiments on fusion reactions produced by adiabatic compression of plasma vortex structures are discussed. The TRISOPS machine at the University of Miami has been modified by improving the preionization of the plasma and increasing the ring frequency of the conical theta-pinch coils. The results obtained with a series of experiments leading up to the

Confining turbulence in plasmas

Physics of Plasmas, 2004
The transport properties of electrostatic turbulence in plasmas are investigated by using test-particle simulations. In particular, the possibility of control of the transport in a given synthetic turbulent field, which evolves both in space and time, is explored.

Electrostatic-Inertial Plasma Confinement

Journal of Applied Physics, 1972
Electrostatic-inertial plasma confinement consists of trapping charged particles in potential wells of the electric field, which are created by ions or electrons injected radially inwards into a hollow sphere or cylinder. Theoretical expressions are derived for the potential and particle densities as functions of radius, grid voltage, and current.

Plasma Confinement Systems

IEEE Transactions on Nuclear Science, 1973
Present plasma confinement systems are reviewed in order to provide an understanding of the developments necessary for demonstrating the scientific feasibility of controlled thermonuclear fusion. Significantly, these systems have several common features which appear certain to be used in more advanced experiments.

Electrostatic-inertial plasma confinement

1990 Plasma Science IEEE Conference Record - Abstracts, 1990
Summary form only given. Electrostatic-inertial confinement offers several significant advantages, including a highly non-Maxwellian plasma which is capable of burning advanced fuels, a relatively simple structure capable of high power density, and a natural connection to direct energy conversion. The plasma is confined in an electrostatic well that is

Melting of Crystalline Confined Plasmas

Physical Review Letters, 2002
The melting of cold, ordered arrays of up to 10 000 charges, confined in external fields, has been studied in simulations. The latent heat associated with melting and the behavior of the specific heat were obtained, along with the spatial correlation function g(r) with respect to neighbors and the diffusion rates, both as a function of temperature. The

Magnetically Confined Plasmas

Physical Review, 1958
The propagation of high-velocity shock waves in an axial maganetic field generated by single-turn coils connected in parallel to a condenser bank is investigated. Time-resolved photographs show that the plasma behind the shock front is driven away from the tube walls by the maganetic pressure, This compression heats the ionized gas and maintains a high

Plasma Confinement Characteristics in Heliotron J—Spontaneous Change of Plasma Confinement State

Plasma Science and Technology, 2004
Spontaneous transition of the plasma confinement mode was observed in the helical-axis heliotron device Heliotron J for three different plasma heating schemes, i.e. ECH-only, NBI-only and the combination of ECH and NBI. The transition seems to occur above a certain critical density.

Numerical simulations of magnetically confined plasmas

Journal of Instrumentation, 2018
Since 2012, the INFN ion source group has been undertaking an intense activity on numerical modelling of magnetically confined plasmas, presently carried out in the framework of the PANDORA project. The aim is the development of a predictive tool for the design of Electron Cyclotron Resonance (ECR) Ion Sources or Traps and ECR-based Charge Breeders ...

Helical Plasma Confinement Devices with Good Confinement Properties

Physical Review Letters, 1997
The criterion of approximate omnigeneity (i.e., having bounce-averaged drift lying within the magnetic surfaces) is much easier to satisfy than quasihelicity, the condition that $B$, the magnitude of the magnetic field, is a function of only a single linear combination of the toroidal angles.
