Adjoint methods for quasisymmetry of vacuum fields on a surface
Richard Nies, Elizabeth J. Paul, Stuart R. Hudson +1
Adjoint methods can speed up stellarator optimisation by providing gradient information more efficiently compared to finite-difference evaluations. Adjoint methods are herein appli…
On the stabilisation of locked tearing modes in ITER and other large tokamaks
Richard Nies, Allan H. Reiman, Nathaniel J. Fisch
Tearing modes in tokamaks typically rotate while small and then lock at a fixed location when larger. Research on present-day devices has focused almost exclusively on stabilisatio…
Enhanced Preconditioner for JOREK MHD Solver
I Holod, M Hoelzl, P S Verma +3
The JOREK extended magneto-hydrodynamic (MHD) code is a widely used simulation code for studying the non-linear dynamics of large-scale instabilities in divertor tokamak plasmas. D…
