DOI: 10.1088/1361-6587/ac43ef
Abstract: No fusion device can be created without some uncertainty; there is always a slight deviation from the geometric specification. These deviations can add up create a deviation of the magnetic field. This deviation is known… read more here.

DOI: 10.1088/1741-4326/ae0ae5
Abstract: Numerical simulations concerning the spectrum of resonant magnetic perturbation (RMP) on field penetration threshold in EAST are presented, since the underlying physics is not well understood by the linear response model. The quasi-linear full MHD… read more here.
