Discovery of spontaneous inflow and outflow states of high-temperature plasma by energetic ions
Background
In the realm of fusion research, the control of plasma density, temperature, and heating is crucial for enhancing reactor performance. Effective confinement of plasma particles and heat, especially maintaining high density and temperature at the core where fusion occurs is essential. In the Large Helical Device (LHD)*1, challenges persist as the electron density profile often remains flat or even depressed at the center, complicating effort to sustain high central density.
Results
The LHD is equipped with five neutral beam (NB) injectors*3 for plasma ...
