DIII-D National Fusion Facility

DIII-D is the largest magnetic fusion facility operating in the U.S. and is considered one of the most flexible and highly instrumented tokamaks in the world. A U.S. Department of Energy national user facility, DIII-D hosts hundreds of collaborators from more than 100 institutions worldwide to conduct research on the cutting edge of fusion energy science and technology. The facility recently underwent a series of upgrades in which multiple new systems were added to provide world-leading capabilities. Researchers at DIII-D are beginning a new experimental campaign focused on solutions for ITER while focusing on sustained operations that will be necessary for future fusion devices. DIII-D is always welcoming to new collaborators seeking a flexible and powerful research environment in which to advance fusion energy science.

Diagnostic Systems for Science Research

GA has driven innovation in fusion diagnostics for more than 50 years and is ready to expand its collaborations in the diagnostic space. GA specializes in cutting-edge, custom diagnostics that require the latest technological advances and scientific research. While we specialize in one-off, newly developed designs, GA is capable of producing smaller batches of diagnostics at the highest standards. The Low Field Side Reflectometer (LFSR) that GA is building for ITER is a good example. LFSR (below) transmits and receives broadband millimeter-wave signals through 100 meters of its low-loss transmission-line system. The diagnostic will provide ITER with real-time measurements of the electron density with millimeter spatial resolution and microsecond temporal resolution.

Plasma Control

The powerful and highly flexible DIII-D Plasma Control System (PCS) is the most widely used in the world, presently operating twelve fusion experiments across the U.S., Europe, and Asia. The system takes an integrated plasma control (IPC) approach to the complex fusion plasma challenge, using the latest modeling techniques backed up with controller verification to achieve high-reliability control with minimal machine operations time for testing and tuning. At DIII-D, dozens of control loops actively regulate the plasma state using measurements from thousands of diagnostic signals and extensive model-based control algorithms. The DIII-D PCS is flexible enough to meet plasma challenges in a variety of complex fusion device configurations and environments.

ITER Central Solenoid

General Atomics is fabricating the ITER Central Solenoid, which will rest at the heart of the ITER tokamak and drive 15 million amperes of current to heat and stabilize the plasma. The Central Solenoid, which will be the largest pulsed superconducting magnet ever built, is being manufactured at GA’s Magnet Technologies Center (MTC), a custom-built facility for fabricating some of the most advanced magnets on the planet. The MTC is fabricating seven modules (six for the Central Solenoid and a seventh as a spare). The first two modules are in final testing. The first module is scheduled to ship to ITER this year, with the rest following over the next two years. GA is seeking partners in need of a facility and highly-trained workforce to build customized, limited-run magnets that feature the latest fabrication techniques.

Microwave Technologies

GA is a world leader in microwave technologies, specializing in end-to-end high-power and low-power transmission systems. Over decades of work on the cutting edge of fusion research, GA developed unique capabilities in microwave control and transmission. GA designs complete systems that can handle high frequency, power, and pulse lengths with low losses, high mode purity, and low reflection back to the source. GA has developed all necessary components for complete transmission systems, including bends, convertors, and adapters.
