Atomic Beam Plasma Diagnostics.
Abstract
The report is concerned with the application of atomic and ionic beams for measurement of electron density and temperature of fusion plasma. The average electron density is determined from the attenuation of an atomic beam. Spectroscopic line ratio measurements along the beam provide information about the electron temperature distribution. Single shot measurements can be made and the data handling automated with an Optical Multichannel Analyzer. The electron density distribution can best be measured with an ion beam. The plasma potential can be determined exactly from the energy difference between secondary and primary ions. Four appendices include completed research on photo- and electron-impact ionization as well as properties of GaAs lasers. (Author)
