Title: TUBT004

Research Question: How does the NSTX control system, specifically the plasma control system, contribute to the operation and understanding of the National Spherical Torus Experiment (NSTX)?

Methodology: The study examined the architecture, components, and functionality of the NSTX control system, with a focus on the plasma control system. It analyzed data acquisition, real-time control systems, and the interaction between engineering and physics systems.

Results: The research found that the plasma control system is a sophisticated, real-time digital control system that plays a crucial role in shaping, positioning, and density of the plasma in the NSTX device. It acquires over 200 input signals and sends new control commands every millisecond. The system features high-speed data links and advanced computing capabilities, enabling it to handle the demanding requirements of the NSTX fusion reactions.

Implications: The study highlights the importance of the plasma control system in the operation and understanding of the NSTX. It also underscores the significance of the collaborative development and open-source nature of the control system software, which allows for continuous enhancement and maintenance by the user community.
