An approach to sustaining steady-state toroidal currents in tokamaks by use of two separate electron cyclotron heating sources is described. One source creates a minority group of collisionless, barely trapped electrons. The second source uses freque

A diagnostic system based on the heavy ion beam probe technique has been developed for the Elmo Bumpy Torus. A variety of singly charged alkali metal ions have been used in the probing beam; detection of multiply charged reaction products allows a co

A heavy-ion--beam probe has been used to measure the space-potential distribution on the Elmo bumpy torus. The results indicate that under optimum confinement conditions the ambipolar electric field is nearly axisymmetric, points radially inward, and

Resonant heating by microwave power has been used to produce high β plasmas with electron temperatures near 1 MeV. Typically plasmas are produced with ωpe~ωce. Further experimental heating studies described here have shown that a large increase in

A high-0 hot-electron plasma was studied in an asymmetric magnetic mirror device with a variable cant angle. The plasma was produced by microwave heating at a frequency corresponding to cold-electron-cyclotron resonance together with a higher frequen

Acceleration of electrons and ions to walls has been observed during plasma instabilities in a hot electron, electron-cyclotron heated plasma. Radioactivity resulting from ( gamma ,n) reactions with thresholds approximately 10 MeV has demonstrated th

The sequence of experiments resulting in the development of steady-state dense hot-electron plasmas is briefly described. These plasmas are produced in magnetic-mirror machines by radiation at the electron-cyclotron frequency. The electron-cyclotron

Neutron emission from the plasma was observed and validated by foil activation measurements. The neutron production rate was optimum when the plasma was adjusted for quiescent steady-state operation. Four methods were used to obtain a rough determina

Silicon barrier detectors have been used to detect H + , H 2 + , and H 3 + by using the detector as a dc current amplifier. Measurements were made in the energy range 2 to 35 keV. The gain of the detector was a linear function of energy for H + energ

The chief virtue of gyrotrons, their capability of producing high average power efficiently at millimeter wavelengths, places special demands on separating high power microwaves in oversized waveguides from high power electron beams. It is possible t
