We tackle the plasma physics in nuclear fusion reactor with flexible ideas.
Introduction of Laboratory
In magnetic confinement fusion reactors, a hot plasma of several hundred million degrees is produced at the centre, but to protect the device walls from various damages, the plasma energy must be converted into light and the peripheral plasma must be radiatively cooled to tens of thousands of degrees. The radiative cooling process of the plasma is, however, full of strong non-linearities, so under what conditions can stable operation be achieved? Also, what happens at the boundary between the high-temperature confinement region and the low-temperature periphery, where an extremely large temperature gradient is formed? These questions will be addressed through experiments and simulations on the Large Helical Device (LHD) at the National Institute for Fusion Science (NIFS), as well as through collaborations with other large overseas devices. In addition, we will challenge new research themes in collaboration with the fields of synchrotron radiation science, astrobiology and astronomy.
