General Atomics is fabricating waveguides, diagnostics, and the world's most powerful pulsed superconducting electromagnet for the international ITER experiment, an unprecedented scientific collaboration of 35 nations that will prove the feasibility of fusion – the process that powers the stars – to produce virtually limitless safe, clean and renewable energy.
The Central Solenoid is the heart of ITER, and the 5-story, 1,000-ton magnet will drive 15 million amperes of electrical current in ITER's fusion plasma for stabilization. Each coil is 7 feet tall, 14 feet wide, and is composed of 3.5 miles of superconducting cable. The completed Central Solenoid is a critical component for ITER.
Building the Heart of ITER
Since the production of this video in 2018, GA has completed fabrication and testing of the first CS module and plans to ship it to France in 2021, followed closely by the second.
GA is developing a range of other technologies for ITER. These include:
- Low energy loss, high-power microwave transmission line components
- Software for real-time plasma control
- Methods to prevent uncontrolled collapse of ITER plasmas and high energy bursts from plasma edge using internal stabilization coils
- Low Field Side Reflectometer (below): A diagnostic using microwaves to measure plasma density profiles
- Wide Angle Visible & Infrared Viewing System: Set of diagnostic cameras to monitor for hot spots in ITER plasma chamber
- Toroidal Interferometer Polarimeter: Diagnostic to measure plasma density distribution
- Archiving methods for storing multi-gigabytes of ITER experimental data
