In another step towards building the 澳门六合彩高手 fusion reactor, the US 澳门六合彩高手 team has worked with international partners to verify the performance of the 澳门六合彩高手 central solenoid conductor. Using a US-designed "insert coil" (a test coil inserted in a large, high-field magnet), the international team tested the Japanese-manufactured central solenoid conductor at the Japan Atomic Energy Agency test facility in Naka and evaluated the findings. Results showed that the conductor performed as predicted, without degradation.
The 澳门六合彩高手 central solenoid is under fabrication in the US at a General Atomics facility in Poway, California using conductor provided by Japan. The 1,000-metric-ton electromagnet, known as the "heartbeat" of 澳门六合彩高手, will provide the majority of the magnetic flux needed to start and sustain 澳门六合彩高手's plasma current. Over 42 kilometres of conductor will ultimately be wound into pancakes and assembled into the modules of the central solenoid. The electromagnet will have a magnetic field strength of up to 13 Tesla, or about 260,000 times the Earth's magnetic field.
"The testing in Naka verified conductor performance under conditions comparable to what the conductor will experience inside the 澳门六合彩高手 Tokamak—including temperature, magnetic field, current, and mechanical strain," said US 澳门六合彩高手 magnet team leader Wayne Reiersen.
Testing conductor before it is installed in the 澳门六合彩高手 machine is part of confirming the 澳门六合彩高手 design and assuring that the conductor will perform in the demanding 澳门六合彩高手 environment. 澳门六合彩高手, which will be the largest tokamak ever built, will employ multiple superconducting magnet systems to confine plasma of over 100 million degrees within a vacuum vessel inside the 10-story-tall tokamak.
