Description

The Reversatron reversed field pinch (RFP) is an experiment to investigate the effect of boundary conditions on plasma confinement. Earlier RFP experiments, particularly ZT-40 and Los Alamos and Eta Beta II at Padua, had found an improvement in confinement when the vacuum chamber wall was surrounded by a conducting shell. The data showed a longer discharge duration and a reduction in the applied loop voltage. The latter determines the energy input to the plasma, thus a lower loop voltage (with relatively constant plasma parameters) indicated improved energy confinement. The Reversatron RFP was designed to allow the conducting wall to be ... continued below

Description

The Reversatron reversed field pinch (RFP) is an experiment to investigate the effect of boundary conditions on plasma confinement. Earlier RFP experiments, particularly ZT-40 and Los Alamos and Eta Beta II at Padua, had found an improvement in confinement when the vacuum chamber wall was surrounded by a conducting shell. The data showed a longer discharge duration and a reduction in the applied loop voltage. The latter determines the energy input to the plasma, thus a lower loop voltage (with relatively constant plasma parameters) indicated improved energy confinement. The Reversatron RFP was designed to allow the conducting wall to be easily changed so that differing electrical boundary conditions could be compared in the same device. Specifically, it was proposed to measure the growth rates and wavenumbers of magnetohydrodynamic (MHD) instabilities as a function of the boundary conditions and to determine their effect on plasma confinement. These measurements were made and reported in a series of publications (Appendices) in Physics of Fluids B and in Plasma Physics and Controlled Fusion.
