Abstract

학위논문 (박사)-- 서울대학교 대학원 : 공과대학 에너지시스템공학부, 2019. 2. 나용수.A small non-axisymmetric (3D) magnetic field can significantly alter the stability and confinement of tokamak plasmas. Its fundamental mechanics are often associated with electromagnetic torque due to the toroidal symmetry breaking and thus corresponding toroidal rotation, which plays an important role to affect various macro-instabilities as well as transport related to micro-instabilities. This thesis presents various investigations on the torque and rotation evolution under 3D magnetic fields applied to KSTAR tokamak plasmas, and contributions to enhanced understanding for a few major consequencessuch as disruptive rotation and plasma collapse due to resonant torque referred to as lock...
