The device, part of the CRAFT artificial sun reactor, sets new international benchmark in push for clean energy
The assembly comprises two coils: a toroidal-field magnet that acts as a magnetic cage, and a central solenoid that serves as the igniter.
The project – the Comprehensive Research Facility for Fusion Technology – aims to create a miniature sun at over 100 million degrees Celsius (over 180 million Fahrenheit) and trap it inside a doughnut-shaped metal cage to generate electricity.
The magnetic cage, known as the CRAFT toroidal field coil, is a core component of the reactor.
It uses a strong magnetic field to prevent the container of the miniature sun from melting as the plasma inside reaches hundreds of millions of degrees.
