“…Equilibrium reconstruction has emerged as a critical tool for tokamak control [4] and in plasma performance optimization [5][6][7][8]. The most widely-used code for equilibrium reconstruction is EFIT [2,3], which has been used at the DIII-D [3,9], C-MOD [10], JET [11], HIT [12], START [13,14], MAST [15], KSTAR [16,17], JT-60U [18], NSTX [19], TORE SUPRA [8,20], HT-7 [21], HL-2A [22], and EAST [23,24] devices. Equilibrium reconstruction is a critical part of the development of the fusion.…”
