Research Abstract |
On UTST, spherical tokamak start-up was demonstrated by merging two initial plasmas, which were generated inside the vessel by using the magnetic field coils located outside the vessel. To optimize the discharge, toroidal field was enhanced and equilibrium field was generated by electric double layer capacitors and IGBTs. Doppler spectroscopy measured the acceleration of the ions in the outflow region, and triple Langmuir probe measured the localized electron heating at the merging X-point.
