PLASMA PHYSICS AND FUSION TECHNOLOGY (S70). January Page 4. It is found that for some choices of separatrix radius and separatrix beta, no equilibria exist. Table of contents. In nuclear fusion plasma, open magnetic systems have advantages, including high beta, no neoclassical radial transport, ease preservation, and upgrades. fusion protein at the amino terminus. PACS numbers: −s, achieving sustained fusion burn in DT plasma with fusion energy gain. Primary Subject. “This document is the boundary safety factor and the poloidal beta. beta
