KSTAR fusion reactor sets a record for high-temperature plasma duration – SlashGear

KSTAR, or the Korean Superconducting Tokamak Advanced Research, reactor is a superconducting fusion device called the Korean artificial sun. KSTAR has set a new world record for maintaining the high-temperature plasma for 20 seconds, reaching an ion temperature of over 100 million degrees Celsius. Scientists working on the project are now aiming to continuously operate high-temperature plasma over 100 million degrees for 300 seconds by 2025.
Achieving an ion temperature higher than 100 million degrees…
