Title: Current State of DIII-D Plasma Control System

Abstract

We present that the DIII-D Plasma Control System (PCS) is a comprehensive software and hardware system used in real-time data acquisition and feedback control of numerous actuators on the DIII-D tokamak. It regulates many plasma characteristics including shape, position, divertor function, and core performance. The custom software developed at DIII-D provides an expandable platform from which new control algorithms can be incorporated. PCS has been expanding with the needs of the DIII-D research program, national, and international institutions that have adapted the PCS for use on their devices. The DIII-D PCS group in collaboration with many national and international groups have been instrumental in steadily improving the effectiveness and capability of the system. Lastly, enhancements on two key areas have been made: computer infrastructure upgrades and real time diagnostics control.

Initial development of the DIII–D snowflake divertor control

Journal Article Kolemen, Egemen ; Vail, P. J. ; Makowski, M. A. ; ... - Nuclear Fusion

Simultaneous control of two proximate magnetic field nulls in the divertor region is demonstrated on DIII–D to enable plasma operations in an advanced magnetic configuration known as the snowflake divertor (SFD). The SFD is characterized by a second-order poloidal field null, created by merging two first-order nulls of the standard divertor configuration. The snowflake configuration has many magnetic properties, such as high poloidal flux expansion, large plasma-wetted area, and additional strike points, that are advantageous for divertor heat flux management in future fusion reactors. However, the magnetic configuration of the SFD is highly-sensitive to changes in currents within the plasmamore »« less

Integrated current profile, normalized beta and NTM control in DIII-D

Journal Article Pajares, A. ; Wehner, W. P. ; Schuster, E. ; ... - Fusion Engineering and Design

There is an increasing need for integrating individual plasma-control algorithms with the ultimate goal of simultaneously regulating more than one plasma property. Some of these integrated-control solutions should have the capability of arbitrating the authority of the individual plasma-control algorithms over the available actuators within the tokamak. Such decision-making process must run in real time since its outcome depends on the plasma state. Therefore, control architectures including supervisory and/or exception-handling algorithms will play an essential role in future fusion reactors like ITER. However, most plasma-control experiments in present devices have focused so far on demonstrating control solutions for isolated objectives.more »« less

Implementation of AI/DEEP learning disruption predictor into a plasma control system

Journal Article Tang, William ; Dong, Ge ; Barr, Jayson ; ... - Contributions to Plasma Physics

This paper reports on advances in the state-of-the-art deep learning disruption prediction models based on the Fusion Recurrent Neural Network (FRNN) originally introduced in a 2019 NATURE publication [https://doi.org/10.1038/s41586-019-1116-4]. In particular, the predictor now features not only the “disruption score,” as an indicator of the probability of an imminent disruption, but also a “sensitivity score” in real time to indicate the underlying reasons for the imminent disruption. This adds valuable physics interpretability for the deep learning model and can provide helpful guidance for control actuators now implemented into a modern plasma control system (PCS). The advance is a significant stepmore »« less

Plasma flux expansion control on the DIII-D tokamak

Journal Article Anand, H. ; Humphreys, D. ; Eldon, D. ; ... - Plasma Physics and Controlled Fusion

A new controller has been developed with help of the flexible divertor poloidal-field coil set of the DIII-D tokamak, to aid in the precise control of the flux expansion in the scrape-off layer (SOL). Here, the single-input multiple-output (SIMO) architecture ensures flexibility through a complementary set of orthogonal actuator direction to guarantee minimum effect on existing controlled variables, e.g. radial and vertical position control of the X-point. A non-linear free-boundary simulation code (GSevolve) is used for simulating the closed-loop response and for verifying the implementation of the control algorithm on the DIII-D plasma control system (PCS).

DIII-D research advancing the physics basis for optimizing the tokamak approach to fusion energy

Journal Article Fenstermacher, M. E. ; Abbate, J. ; Abe, S. ; ... - Nuclear Fusion

DIII-D physics research addresses critical challenges for the operation of ITER and the next generation of fusion energy devices. This is done through a focus on innovations to provide solutions for high performance long pulse operation, coupled with fundamental plasma physics understanding and model validation, to drive scenario development by integrating high performance core and boundary plasmas. Substantial increases in off-axis current drive efficiency from an innovative top launch system for EC power, and in pressure broadening for Alfven eigenmode control from a co-/counter-I_p steerable off-axis neutral beam, all improve the prospects for optimization of future long pulse/steady state highmore »« less
