Axisymmetric reduction of the adjoint operator in ideal MHD equilibrium
Fumiya Tanji, Akinobu Matsuyama, Akio Sanpei +3
Adjoint formulations of magnetohydrodynamic (MHD) equilibrium are presented for sensitivity analysis and optimization-based equilibrium calculations. We derive the adjoint of the t…
Augmented reality system for visualising magnetic field topology and charged-particle trajectories in magnetic fusion plasmas
Akinobu Matsuyama
A cost-effective augmented reality (AR) system is presented for visualising three-dimensional magnetic field structures and charged-particle trajectories in magnetically confined f…
Construction and analysis of guiding center distributions for tokamak plasmas with ambient radial electric field
Andreas Bierwage, Philipp Lauber, Noriyoshi Nakajima +8
The contribution of a time-independent toroidally-symmetric radial electric field is implemented in VisualStart [Comp. Phys. Comm. 275 (2022) 108305; arXiv:2111.08224], a cod…
Modelling of shattered pellet injection experiments on the ASDEX Upgrade tokamak
Ansh Patel, Akinobu Matsuyama, Gergely Papp +13
In a shattered pellet injection (SPI) system the penetration and assimilation of the injected material depends on the speed and size distribution of the SPI fragments. ASDEX Upgrad…
