South Korean Tokamak KSTAR established a new world record

On Tokamak KSTAR at the Korean institute thermonuclear energy (KFE) heated plasma to 100 million °C and held it in a stable condition of 30 seconds. Researchers without false modesty declare that it is a turning point on a way to a commercial thermonuclear reaction. To plasma deduction in Tokamak apply a magnetic method. Use magnetic fields of two forms. In one experiments — krayevy a transport barrier round plasma which causes sharp pressure decrease in a reactor wall. In others — a vnutrenny transport barrier which creates more high pressure near the plasma center. However both...
