The National Institutes of Natural Sciences National Institute for Fusion Science (NIFS) has succeeded in revealing the flow of negative hydrogen ions using a combination of infrared lasers and electrostatic probes in the ion-source plasma, which generates a negative-hydrogen-ion beam. This is the first time in the field of fusion research that the detailed ion flow, which changes direction and moves toward the beam direction in the ion source, has been demonstrated experimentally.
