Exploring Scenario and Reactor Requirements for Active TM Stabilization with real-time ECH Steering

2024 Research Campaign, Steady State and Pulsed Fusion Core

Purpose of Experiment

The objective of this experiment is to explore the viability of advanced scenarios and operation requirements for fusion pilot plant operation in the presence of tearing modes (TMs).

Experimental Approach

Using a new TM prediction model using a deep survival machine framework, we achieve improved TM prediction that will be used to improve electron cyclotron heating (ECH) multitasking. This will enable better scenario performance because less of the limited ECH power will be dedicated to TM suppression. The experiment will also explore ways to improve passive TM stability by utilizing Bayesian optimization to modify the ECH deposition profiles from shot to shot.
