Korea's superconducting tokamak KSTAR has run successfully since 2008. In December 2016, the machine produced a record 70-second high-performance plasma (H-mode) and achieved record-length periods of ELM suppression the following year.
Although smaller and different in detailed design, the Korean machine has built an extremely valuable database for the future operation of ±¬×ߺÚÁÏ.
On 4 September, KSTAR passed an important milestone: at 11:20 a.m., the machine produced its 20,000th plasma shot—all of them achieved without accident or major repair.
