Abstract

The construction of 500 keV NBI system using negative-ions has started for studying of mega-ampere level NB current drive and plasma core heating experiments with a high density reactor-like plasma In JT-60U. The specification of the NBI system is; a beam energy of 500 keV, an injection power of 10 MW, a beam duration time of 10 sec with a duty cycle of 1/60, a beam species of deuterium or hydrogen. The power of 10 MW is injected toward tangential/co-direction with one beamline that has two negative-ion sources. The construction of the NBI system will be completed in 1996
