Control demonstrations obtained during TCV experiments. Target shape points with 2 cm radius (blue circles), compared with the equilibrium reconstruction plasma boundary (black continuous line). In all figures, the first time slice shows the handover condition.  a , Elongation of 1.9 with vertical instability growth rate of 1.4 kHz.  b , Approximate ITER-proposed shape with neutral beam heating (NBH) entering H-mode.  c , Diverted negative triangularity of −0.8.  d , Snowflake configuration with a time-varying control of the bottom X-point, where the target X-points are marked in blue. Extended traces for these shots can be found in Extended Data Fig. 2.
