The high poloidal-beta (β P) regime was first proposed as a high bootstrap current scenario
for a steady-state fusion pilot plant (FPP) in the 1990s (Kikuchi in Nucl Fusion 30: 265 …

The tokamak approach, utilizing a toroidal magnetic field configuration to confine a hot
plasma, is one of the most promising designs for developing reactors that can exploit …

A record duration of a 310 s H-mode plasma (H 98y2∼ 1.3, ne/n GW∼ 0.7, f BS> 50%) has
been recently achieved on experimental advanced superconducting tokamak (EAST) with …

To address the needs for a fusion pilot plan design, DIII-D/EAST joint experiments on DIII-D
have demonstrated high normalized beta β N∼ 4.2, toroidal beta β T∼ 3.3% with q min> 2 …

The main purpose of this thesis is the validation of the gyrokinetic method in the near-edge
region of L-mode plasmas. Our primary finding is that gyrokinetic simulations are able to …
