Japans Tokamak-Kernfusionsreaktor stellt mit einem Plasmavolumen von 160 Kubikmetern einen Weltrekord auf

> 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.

> A series of operations was conducted to check the performance of JT-60SA. The series started with vacuum pumping on JT-60SA, cooling superconducting coils, and coil energization tests, after which plasma was actually produced, and scientists confirmed the overall performance of JT-60SA, including its control, according to a release.
