The ARIES-AT design has an aspect ratio of A ≡ R/a = 4.0, an elongation and triangularity of κ = 2.20, δ = 0.90 (evaluated at the separatrix surface), a toroidal beta of β = 9.1% (normalized to the vacuum toroidal field at the plasma center), which corresponds to a normalized beta of βN ≡ 100 × β/(IP (MA)/a(m)B(T )) = 5.4. These beta values are chosen to be 10% below the ideal MHD stability limit. The bootstrap- current fraction is fBS ≡ IBS /IP = 0.91. This leads to a design with total plasma current IP = 12.8 MA, and toroidal field of 11.1 T (at
