摘要：

The long pulse experiments in the Large Helical Device has made progress in sustainment of improved confinement states. It was found that steady-state sustainment of the plasmas with improved confinement at the core region, that is, electron internal transport barrier (e-ITB), was achieved with no significant difficulty. Sustainment of a plasma having e-ITB with the line average electron density n(e_ave) of 1.1 x 10(19) m(-3) and the central electron temperature T-e0 of similar to 3.5 keV for longer than 5 min only with 340 kW ECH power was successfully demonstrated.
