A negative-ion-based NBI test-stand has been constructed in Toki site of National Institute for Fusion Science (NIFS). This Toki test-stand has facilities to produce 2.5 MW neutral beam power with the energy of 125 keV for hydrogen and 250 keV for deuterium, which is utilized for developing a unit of neutral beam injection (NBI) system for Large Helical Device (LHD). All components of the Toki test-stand are installed on the basis of conceptual design of the LHD-NBI system. Development of a high-current negative ion source with vacuum-immersed structure is one of the main objectives of the test-stand, as well as transport of a high-energy beam with a small divergence angle. It is also an important subject to test all of hardware components such as beam dumps and cryo-pumps. Experiments started in July.
