Steady-state thermonuclear power generation in a two-energy-component Astron device

Nuclear Fusion, 1975
Studies are reported on a steady-state two-component Astron device. The basic idea is to confine a tritium plasma in a field- reversing deuterium ion layer and generate thermonuclear power from the optimized layer-plasma fusion reactions. The system is maintained at a steady state by the injection of neutral deuterium beams (150-300 keV).

THERMONUCLEAR FUTURE OF THE TOKAMAK MAGNETIC CONFINEMENT DEVICE.

Nuclear Fusion, 1969
A possible extrapolation of the Tokamak principle towards a thermonuclear reactor raises many problems among which stress is laid on the minimum values required for the equilibrium and stability parameters. Some technological requirements are confronted with the most recent theoretical developments, revealing the existence of a small domain inside of ...

Accessibility of the lower hybrid resonance in thermonuclear devices

Nuclear Fusion, 1974
The condition for efficient coupling of a high-frequency wave at the lower hybrid resonance is discussed for grazing-angle incidence. Scaling laws are derived, which show that the optimistic results recently produced numerically by Puri and Tutter cannot be extrapolated to densities of thermonuclear interest.

Scattering theory of strongly refracting microwaves in turbulent inhomogeneous plasma. Applications of the theory to the description of fluctuation reflectometry in thermonuclear fusion devices

Physics-Uspekhi, 2021
Abstract We present the theory of propagation and scattering of strongly refracting microwaves in turbulent inhomogeneous plasmas. We calculate the scattered signal amplitude in the case of a linear scattering regime in the Born approximation and in the case of multiple small-angle scattering. We discuss the possibility of an analytic

Levitation of Current Carrying Hoops of Quadrupole Magnetic Field for Thermonuclear Fusion Device

Journal of Nuclear Science and Technology, 1969
A simple and reliable method of levitating current-carrying hoops of a quadrupole magnetic field for thermonuclear fusion devices is presented. The hoops are initially posed on three supports, which are then propelled downward by repulsive force generated in a magnetic coil fed from a capacitor bank, leaving the current carrying hoops gravitating in ...

THE CORRELATION BETWEEN OF DISCHARGE CURRENT AND NEUTRON EMISSIONS IN THE THERMONUCLEAR PLASMA FOCUS DEVICE

NNC RK Bulletin, 2020
The dynamic characteristics of the discharge current in a thermonuclear plasma focus installation and its dependence on neutron emission was studied. The dynamics of the formation of discharge pickcurrent was measured and analysed through the Rogowskiy belt and activated neutron flux with an activated silver foil detector.

A two-stage pellet injector with a cryogenic piston for plasma fueling of thermonuclear devices

Instruments and Experimental Techniques, 2000
A new two-stage gun was developed for solid-hydrogen-or deuterium-pellet formation and injection into plasma of thermonuclear devices. A cryogenic piston made from solid carbon dioxide was first used to compress and heat the propellant gas in the second gun stage. The piston was produced simultaneously with fuel pellets before each shot.

XPS, SIMS and FTIR-ATR characterization of boronized graphite from the thermonuclear plasma device RFX-mod

Applied Surface Science, 2015
Abstract In this paper the characterization of a thin (tens of nanometers) boron layer on fine grain polycrystalline graphite substrate is presented. The boron film is used as conditioning technique for the full graphite wall of the Reversed Field eXperiment–modified (RFX-mod) experiment, a device for the magnetic confinement of plasmas of ...

Neutron flux distribution on the wall of toroidal controlled thermonuclear reactor devices with elongated cross section

Zeitschrift für Physik, 1974
The neutron flux distribution on the wall of a toroidal CTR device with strongly elongated cross section is calculated. On the inner and outer cylindrical walls (belt-pinch device) the flux distribution has a plateau region with a half-width equal to about the height of the plasma.
