Fusion energy is being developed as a solution to global energy problems. In particular, the magnetic confinement method, in which ultra-high temperature plasma is confined by a magnetic field, is the ...

The Large Helical Device (LHD) and the heavy ion beam probe (HIBP) system. The inset on the left shows an enlarged view of the section from the negative ion source to the injection side of the tandem ...

Nuclear fusion, which operates on the same principle that powers the sun, is expected to become a sustainable energy source for the future. To achieve fusion power generation, it is essential to ...

Fusion plasma research centres on realising controlled thermonuclear reactions, with effective diagnostics playing an indispensable role in understanding plasma conditions and fast ion behaviour. Fast ...

China’s flagship fusion experiment has pushed its superheated fuel into a regime that many physicists once dismissed as unattainable, reaching a plasma density that earlier models said would tear the ...
