This project will assess the feasibility of enhancing the performance of toroidal devices for magnetic confinement of fusion plasmas by using high-beta, hot-electron, surface- layer plasmas. the objective of this enhancement is to permit stable operation at substantially higher values of beta than… More

Gas, a magnetized plasma stream can function as a high-speed vacuum pump with unique technical advantages. to realize these advantages in a practical way, it is essential to utilize an efficient electron heating technique to create the plasma and maintain the optimal electron temperature. the… More

Relativistic-electron plasmas, created and sustained by electron cyclotron heating (ech) in magnetic- mirror fields, have many promising applications. they can be used to stabilize plasma confinement configurations, such as the elmo bumpy square, the heliac, and even tokamaks; and they can enchance… More

This project will assess the requirements and provide a basis for designing an optimized system for a tokamak reactor to reach the high-beta, "second stability regime" from startup, using electron cyclo- tron heating (ech) techniques. the power needed to achieve a stable plasma evolution to the… More

The thermal-barrier concept for tandem magnetic mirrors has greatly inhanced the attractiveness of this approach to confining high-temperature plasmas for fusion power. transient existence of thermal barriers has already been demonstrated in the tmx experiment at livermore and in the gamma 10… More

For the optimization of tokamak performance, the international fusion energy community generally has a need for current density profile measurements. to accomplish such measurements, it is planned to accelerate unpolarized ground state atoms (hydrogen or helium) along a chord through the plasma to a… More

A robust method for achieving stochastic heating of ionospheric electrons to relativeistic energies is proposed that uses multiple frequency electron cyclotron heating (mfech): electromagnetic radiation from ground based antennas is focused on a suitable region of the earth's magnetosphere; and the… More

High vacuum plasma pumping offers an important, attractive, and viable method of producing vacua. since no mechanical moving parts are employed, it is inherently rugged. moreover, it can achieve high values of hydrogen and helium throughput with excellent flexibility and speed. a high vacuum plasma… More

A novel high power millimeter/microwave source is proposed in which two interpenetrating streams of electrons, flowing through a background plasma in a static magnetic field are used to generate a hot-electron plasma that is confined in a mirror-like magnetic field in the form of a folded-cusp… More
