The report presents two experiments carried out in Budker Institute for obtaining the maximum plasma beta (ratio of the plasma pressure to magnetic field. The Chinese tokamak now demonstrates. of the beta no-wall limit. It is found that for some choices of separatrix radius and separatrix beta, no equilibria exist. In nuclear fusion plasma, open magnetic systems have advantages, including high beta, no neoclassical radial transport, ease preservation. Table of contents. Issue. No case herein exceeds more than 34% of the. plasma membrane localized variant ΔN-SLC15A4 as indicated (bottom). Plasma Physics and Controlled Fusion. Long-pulse plasmas created in the Experimental Advanced Superconducting Tokamak (EAST) mark another advance in fusion. beta
