First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. ...
Discovery of spontaneous inflow and outflow states of high-temperature plasma by energetic ions
In the realm of fusion research, the control of plasma density, temperature, and heating is crucial for enhancing reactor performance. ...
25 years of massive fusion energy experiment data completely open on the “cloud”, to be available to everyone
High-temperature fusion plasma experiments conducted in the Large Helical Device (LHD) of the National Institute for Fusion Science (NIFS), have renewed the world record for an acquired data amount. ...
The discovery of new turbulence transition in fusion plasmas: The road to innovative operation scenarios for fusion power plants
Fusion energy is that released when two light nuclei combine to form a single heavier one (nuclear fusion reaction). ...
Laboratory study on conditions for spontaneous excitation of "chorus emission," wave of space plasma: Exploring common plasma phenomena in laboratory and space through experiments in the RT-1 artificial magnetosphere
The whistler mode chorus emission in the space around planets is an important wave that plays a significant role in phenomena such as aurorae and "space weather". ...
First demonstration of predictive control of fusion plasma by digital twin: Application of data assimilation to adaptive predictive control
In order to realize fusion power generation using the magnetic confinement method, it is necessary to control ultra-high temperature plasmas exceeding 100 million degrees Celsius over a long period of time. ...
