South Korea's KSTAR Tokamak Sets New Record

South Korea’s KSTAR tokamak has again extended the record confinement time at a temperature of 100 million degrees C or higher, to 30 seconds. The record has been rising steadily over the past 18 months, going back and forth between the KSTAR, at the Korea Institute of Fusion Energy which reported this achievement, and China’s Experimental Advanced Superconducting Tokamak, or EAST. These significant advances continue to be achieved with very low plasma densities, however, so not many fusion events are actually going on.
