If technological level of not only plasma control technology but whole humanity advances, the day when it can generate electricity by fusion reaction of an ideal combination may come.(Answer: National Institutes of Natural Sciences National Institute for Fusion Science· Atsushi Ito Associate Professor) Q78:After acquiring learning.
Your knowledge of plasma physics will help you understand lectures better.- After the Interview- At the front gate of the National Institute of Fusion Science During the 50-minute interview, I felt his great passion from the way he talked about his research earnestly and sometimes with humors.
Research Updates/ National Institute for Fusion Science Experiment-based research that aims at achieving the future fusion energy is moving forward in the Large Helical Device(LHD). Benefitting from recent, rapid advances in supercomputers, we are working too on integrated simulation research that reproduces computer simulations of the complicated behavior of extreme high-temperature plasma that has been observed in LHD experiments.
Research Updates/ National Institute for Fusion Science In the Large Helical Device(LHD), one of the methods used for heating plasma that has been confined by the magnetic field lines container is the NBI(a neutral particle injection heating device; Neutral Beam Injection), which is a method that injects into plasma a hydrogen atom beam that has been accelerated by high energy.
At the National Institute for Fusion Science we are preparing experiments for the Large Helical Device(LHD) that will utilize deuterium in order to improve plasma performance. In deuterium plasma, which bears a mass twice that of light hydrogen which has been used to date, an important issue is clarifying what types of changes will occur in turbulence and in energy confinement.
Since high temperature and high density are necessary to cause nuclear fusion, nuclear fusion reactions are thought to occur only near the center of the star.(Answer: National Institutes of Natural Sciences National Institute for Fusion Science· Atsushi Ito Associate Professor) Q75:Please tell me about neutron-resistant(resistant) substances.
Research Updates/ National Institute for Fusion Science In a magnetic confinement fusion experimental device such as the Large Helical Device(LHD), we confine high-temperature plasma through the strength of the magnetic field. In experimental devices using the inertial confinement method, powerful laser lights from all directions are aimed at a fuel target composed of solid hydrogen, and that solid hydrogen is converted into a high-temperature, high-density plasma state.
Indeed, subjected to heat plasma terminates Department as the material of the component, in addition to the high melting point metal such as tungsten, it is also studied the possibility of liquid metal.(Answer: National Institutes of Natural Sciences National Institute for Fusion Science· Atsushi Ito Associate Professor) Q72:I think that there was a way to use laser beams before fusion, but what is the valid surname?
