摘要: The lithium tokamak experiment (LTX) is a modest-sized spherical (R0=0.4 m and a=0.26 m) designed to investigate the low-recycling wall operating regime for magnetically confined plasmas. LTX will reach this through lithium-coated shell internal vacuum vessel, conformal plasma last-closed-flux surface, heated 300–400 °C. This structure highly conductive not axisymmetric. three-dimensional nature of causes eddy currents magnetic fields be as well. In order analyze equilibrium in presence currents, an extensive array unique diagnostics has been implemented. Sensors are survive high temperatures incidental contact with provide data on toroidal asymmetries well full coverage poloidal cross-section. utilized determine effects nonaxisymmetric model start-up ph...
