Here is the news.
China has hit another milestone in the development of of its next generation artificial sun with one of its key systems passing expert review and acceptance procedures,
recently achieving an internationally advanced development and operational capability standard.
The 1:8 vacuum chamber and overall installation system was developed by the Chinese Academy of Sciences Institute of Plasma Physics.
It is one of the 19 key subsystems of of the Comprehensive Research Facility for Fusion Technology or craft a platform on which engineers develop and test the key components of fusion energy reactors.
Resembling an orange slice,
the newly approved system features a D shaped cross section with a double layer shell and stands 20 metres tall.
The vacuum chamber shell, made of ultra low carbon stainless steel, weighs 295 tons.
In the future,
eight of these orange slices will form a complete structure housing plasma at temperatures exceeding 100 million degrees Celsius.
Liu Zhihong, a researcher at ASIP and the system's lead scientist,
explained that the vacuum chamber serves as the closest nuclear safety barrier to a reactor core,
requiring extreme precision in terms of welding, structural integrity and magnetic permeability.
The research team spent a decade overcoming technical challenges in their development of the system,
securing more than 40 invention patents along the way.
The ultimate goal of an artificial sun is to create nuclear fusion like the sun,
providing humanity with an endless clean energy source and enabling space exploration beyond the solar system.
China is making significant strides in fusion energy with its experimental advanced superconducting tokamak or east,
