Abstrakt: A 105 kJ theta-pinch device with a negative bias magnetic field is used to produce plasmas in hydrogen, deuterium, helium, and neon gases. The radial distribution of electron density and temperature is determined as a function of time in the midplane by Thomson scattering. An array of magnetic probes and one flux loop make it possible to measure the plasma diamagnetism and some other important parameters during the first phase of the discharge. The flux retention and other equilibrium properties are derived by fitting a rigid-rotor profile to the experimental density data. These results are compared with theoretical and semiempirical predictions. [ABSTRACT FROM AUTHOR]
