Trajectory of a compact toroid tangentially injected into a tokamak

摘要

A compact toroid(CT)penetrating into a tokamak discharge is modelled as a con- ducting solid sphere with an intrinsic magnetic moment. Equations of CT motion in tokamak dis- charges are derived and use to calculate the trajectory of a CT with parameters pertinent for pen- etrating the ITER tokamak. The advantage of tangential CT injector and the optimal direction of the initial magnetic moment are discussed.
