A 500keV/10MW negative-ion based NBI system for JT-60 has been completed in March 1996 and an injection experiment has started. This system is the first NBI system based on negative-ions, which is considered to be the first candidate as a plasma heating and current drive device for the ITER (International thermo-nuclear fusion experimental reactor), and the purpose of the system is to prove physically and technically the feasibility of realizing the negative-ion based NBI system. Prior to the completion of the whole NBI system, an ion source-power supply coupling test has been conducted to confirm the performance of negative-ion generation and beam acceleration with a part of the NBI system completed in March 1995. In the test between June and October 1995, a deuterium negative-ion beam has reached an acceleration current of 13.5A, ion beam power of 5.4MW at the beam energy of 400keV, which is the world highest negative-ion beam power. The whole NBI system has completed in December 1995. After confirming the performance of two ion sources, beamline and power supply, a deuterium beam of 180keV, -0.1MW has been injected into the JT-60 plasma successfully in March 1996.
