At its heart is a spherical device called the EXL-50U – a compact tokamak that uses a magnetic field to confine charged gas, or plasma, to fuse hydrogen nuclei.
On the day the South China Morning Post visited, engineers were installing new neutral beam – or heating – systems to increase its plasma temperature.
