In the Super-X case (density ramp from Greenwald fraction 0.12 to 0.24), the upper divertor showed ground state rotational temperatures of the $\\text{D}_{2}$ molecules increasing from $\\sim$6000 K, starting at the detachment onset, to $\\sim$9000 K during deepening detachment. This was correlated with the movement of the Fulcher emission region, which is correlated with the ionisation source. ","authors_text":"B. Lipschultz, E. Pawelec, K. Verhaegh, M.D. Bowden, N.
