  1. > A tokamak device, JT-60SA, jointly developed by Japan and Europe, has achieved a plasma volume of 160 cubic meters. The achievement has been officially certified by Guinness World Records, far exceeding the previous record of 100 cubic meters achieved by other previous devices.

    > JT-60SA uses powerful superconducting coils cooled to approximately -452.2 degrees Fahrenheit (absolute temperature of approximately 4K) to confine plasma that can reach 212 million degrees Fahrenheit of temperature.

    > It’s claimed that the JT-60SA addresses the main aspects of fusion research, from plasma physics to engineering, with special attention to their combination into tokamak operation.

    > The JT-60SA possesses unique capabilities, including the ability to generate long-pulse, high-beta, and highly shaped plasmas.

    > The plasma control method used can contribute to the control of larger plasmas planned for ITER and DEMO reactors. DEMO will be developed based on the results of JT-60SA and ITER and is a device to demonstrate the power generation and economic efficiency of fusion energy.
