Interpretative 3D MHD modelling of deuterium SPI into a JET H-mode plasma

Publikováno v: Nuclear Fusion, Vol 64, Iss 6, p 066004 (2024)

The pre-thermal quench (pre-TQ) dynamics of a pure deuterium ( $\mathrm{D}_2$ ) shattered pellet injection (SPI) into a $3\,\mathrm{MA}$ / $7\,\mathrm{MJ}$ JET H-mode plasma is studied via 3D non-linear MHD modelling with the JOREK code. The interpre

Tokamak divertor plasma emulation with machine learning

Autor: G.K. Holt, A. Keats, S. Pamela, M. Kryjak, A. Agnello, N.C. Amorisco, B.D. Dudson, M. Smyrnakis

Publikováno v: Nuclear Fusion, Vol 64, Iss 8, p 086009 (2024)

Future tokamak devices that aim to create conditions relevant to power plant operations must consider strategies for mitigating damage to plasma facing components in the divertor. One of the goals of MAST-U tokamak operations is to inform these consi

Surface temperature measurement from infrared synthetic diagnostic in preparation for ITER operations

Autor: M.-H. Aumeunier, A. Juven, J. Gerardin, C-M. B. Cisse, S. Pamela, R. Miorelli, C. Reboud, F. Retailleau, J. Marot, F. Rigollet, L. Marot

Publikováno v: Nuclear Fusion, Vol 64, Iss 8, p 086044 (2024)

The protection of ITER in-vessel components and the plasma-wall interaction studies will be based on a large network of infrared (IR) cameras covering 70% of the tokamak. The surface temperature measurement from IR images remains challenging due to t
