Validation of the static forward Grad-Shafranov equilibrium solvers in FreeGSNKE and Fiesta using EFIT++ reconstructions from MAST-U

Autor: Pentland, K., Amorisco, N. C., El-Zobaidi, O., Etches, S., Agnello, A., Holt, G. K., Ross, A., Vincent, C., Buchanan, J., Pamela, S. J. P., McArdle, G., Kogan, L., Cunningham, G.

A key aspect in the modelling of magnetohydrodynamic (MHD) equilibria in tokamak devices is having access to fast, accurate, and stable numerical simulation methods. There is an increasing demand for reliable methods that can be used to develop tradi

Emulation Techniques for Scenario and Classical Control Design of Tokamak Plasmas

Autor: Agnello, A., Amorisco, N. C., Keats, A., Holt, G. K., Buchanan, J., Pamela, S., Vincent, C., McArdle, G.

Publikováno v: Physics of Plasmas 2024 Vol.31, Issue 4

The optimisation of scenarios and design of real-time-control in tokamaks, especially for machines still in design phase, requires a comprehensive exploration of solutions to the Grad-Shafranov (GS) equation over a high-dimensional space of plasma an

Acceptance tests of Hamamatsu R7081 photomultiplier tubes

Photomultiplier tubes (PMTs) are traditionally an integral part of large underground experiments as they measure the light emission from particle interactions within the enclosed detection media. The BUTTON experiment will utilise around 100 PMTs to

When monitoring a reactor site for nuclear nonproliferation purposes, the presence of an unknown or hidden nuclear reactor could be obscured by the activities of a known reactor of much greater power nearby. Thus when monitoring reactor activities by
