“…( 29) with the proportionality constant given by the fitting procedure can be used to predict the SOL width for future tokamaks, such as ITER, COMPASS Upgrade, JT-60SA, and DTT. Considering the baseline scenario just before the L-H transition, one obtains λ q,th 3.5 mm for ITER (R 0 = 6.2 m, a = 2 m, q = 2, P SOL = 18 MW, κ = 1.4, ne = 4 • 10 19 m −3 , and B T = 5.3 T [78]), λ q,th 1.8 mm for COMPASS Upgrade (R 0 = 0.89 m, a = 0.27 m, q = 2.6, P SOL = 3.7 MW, κ = 1.8, ne = 2 • 10 20 m −3 , and B T = 5.0 T [79]), λ q,th 7.1 mm for JT-60SA (R 0 = 2.9 m, a = 1.2 m, q = 3, P SOL = 10 MW, κ = 1.9, ne = 6.3 • 10 19 m −3 , and B T = 2.3 T [80]), and λ q,th 3.0 mm for DTT (R 0 = 2.1 m, a = 0.6 m, q = 3, P SOL = 15 MW, κ = 1.7, ne = 1.8 • 10 20 m −3 , and B T = 6.0 T [81]). The theoretical value of λ q for ITER Lmode is within the range of values predicted by the experimental scaling laws derived in Ref.…”
