TCV intrinsic torque in balanced NBI experiment

Counter-current intrinsic rotation is typical for limited Ohmic plasmas on TCV [10]. Therefore, the counter-current intrinsic torque obtained in the balanced NBI discharge #78931 is not surprising. It could be consistent with momentum flux produced by current-symmetry breaking [11], where our current and magnetic field configuration results in counter-current torque (see the B I_P case of Fig. 4 in [11]). However, more work is needed for conclusive physics statements. Future experiments will leverage electron cyclotron heating and real-time density control to quantify the intrinsic torque in various configurations and physical conditions, aiming to improve statistics and develop predictive capabilities. For more accurate estimates of transport contributions, dedicated gyrokinetic calculations for TCV are needed.
