Abstract

In the advanced operation scenarios in ITER, such as hybrid or steady-state scenarios, active real-time control of plasma profiles is essential to achieve and sustain burning plasmas with sufficient performance. Among the developed plasma profile control approaches, a potentially robust plasma profile control approach for simultaneous control of plasma profiles has been applied to ITER discharge simulations [1] and has been demonstrated in KSTAR experiments [2]. We have extended this control approach to TCV to experimentally demonstrate the capability of q profile control. In this work, as a preparation of the experiment, we have performed simulations for simultaneous control of the i (=1/q) profile and the plasma beta (β) using a transport simulator RAPTOR [3]. As actuator sharing is an important issue in ITER, the profile control approach has been combined with NTM control in ITER simulations.
