12.2. Key scientific achievements of 15 years of MAST research
Together with NSTX (see Chapter 11), MAST has moved the ST research into the domain of hot and dense plasmas. Core temperatures of Ti ≈ 3 keV and Te ≈ 2 keV have been achieved simultaneously in L-mode plasmas with core densities ne ≈ 3 × 1019 m−3 at Ip = 1.2 MA even with moderate heating power . This enabled strong contributions to the three main pillars of research on MAST: ITER and DEMO physics, future ST concepts and basic science.
12.2.1. Plasma confinement
Optimising plasma confinement at a given plasma current and toroidal field is the prime goal for any magnetic confinement fusion device, and the plasma confinement on MAST is very similar to the confinement observed in conventional ...
