NIMROD simulations of reconnection during LHCD in C-Mod

We examine the role of reconnection during LHCD experiments in C-Mod. Some of these experiments exhibit strong MHD activity after application of LH current drive. Here we employ the resisitive magnetohydrodynamic code NIMROD to examine growth time and severity of both core and edge modes during LHCD experiments with MHD activity in C-Mod. To examine the role of reconnection, we first use high aspect ratio C-Mod equilibrium profiles from EFIT from LHCD experiments. We find that the core n=1 reconnecting mode, as well as edge resonant resistive modes localized near the edge, are unstable. We perform a Lundquist number scan, and find that growth rates of both core and edge modes scale with a negative power of the Lundquist number. The nature of edge peeling-like modes, created when the edge peak current density is sufficiently peaked [F. Ebrahimi, Phys. Plasmas 24, 056119 (2017)], as well as preliminary nonlinear results will be presented.
