Abstract :
Summary form only given, as follows. West Virginia University´s large experiment on instabilities and anisotropies (LEIA), is designed to study high beta space plasma phenomena. Presently, instabilities involving nonisotropic ion distributions (different parallel and perpendicular temperatures) are being investigated. Control of the temperature anisotropy is necessary to study these instabilities. Measurements of the ion temperature anisotropy in LEIA and in the steady-state helicon source (HELIX), which generates the plasma for LEIA, as a function of source RF power, source pressure, and magnetic field in both the source and LEIA will be presented.
