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…

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…

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…

Testing the conservative character of particle simulations: I. Canonical and noncanonical guiding center model in Boozer coordinates

Andreas Bierwage, Roscoe B. White, Akinobu Matsuyama

The guiding center (GC) Lagrangian in Boozer coordinates for toroidally confined plasmas can be cast into canonical form by eliminating a term containing the covariant component $B…
