The SUNIST Laboratory

The SUNIST laboratory is a place to discover new physics and to invent new technologies that may make fusion as an affordable and infinite energy for human as soon as possible.

The pathway currently selected by the lab is the spherical tokamak. Currently, the lab is operating a spherical tokamak named SUNIST and constructing a new spherical tokamak named SUNIST-2.

The SUNIST spherical tokamak is a fully mature research device. It started operation from Nov. 2002, majorly upgraded in 2008. Its main parameters are:

  • Major / minor radius: 0.3 / 0.23 m
  • Toroidal magnetic field on axis: < 0.27 T
  • Plasma current: < 120 kA
  • Electron density: ~1E19 m-3
