The first scintillator-based Fast-Ion Loss Detector (FILD) was installed in MAST-U as part of its main upgrade and it was commissioned during the first experimental campaign. FILD works as a magnetic spectrometer, directly measuring neutral beam injection (NBI) fast-ion losses using a scintillator plate that emits light when fast ions impinge on it…

This article starts with a brief description of two new viewing systems with a light path which crosses the biological shield wall and are compatible with Deuterium-Tritium (D-T) operations in JET. However, it focuses on the optical modelling and engineering design of one of them which is a multiple camera system producing a wide angle view (WAV)…

Following from the paper describing the remote wide angle viewing system compatible with Deuterium-Tritium operations. This is the second article describing a second remote line of sight, this time focusing on the imaging of the divertor region in JET. It explains in detail the optical and engineering designs of constructing an optical relay which …

Divertor detachment requires plasma-neutral interactions which dissipate momentum, power and particles simultaneously. Plasma-molecular interactions can result in molecular ions which react with the plasma. This can contribute to detachment through molecular activated recombination (MAR) and molecular activated dissociation (MAD), both of which cre…

In this paper we a first qualitative analysis of the atomic and molecular processes at play during detachment in the MAST-U Super-X divertor, using divertor spectroscopy data. Our analysis indicates a wide operational regime of detachment of the MAST-U super-X divertor, which can be roughly separated in four phases: 1) The ionisation fro…

The commercial exploitation of nuclear fusion energy for electricity production is now nearer than previously imagined. Several organisations are developing fusion reactors with the aim of demonstrating electricity production in the 2030s. These timescales suggest that conceptual designs are being worked on now and the detailed design, construct…

Developing a robust safety case is a key step in the development of a fusion power reactor for electricity generation. Plans for fusion power reactors are already underway and before nuclear facilities are licensed, they must demonstrate they satisfy several safety objectives involving keeping workers and the public safe and limiting any environ…

The JET outboard divertor targets are the in-vessel components which receive the largest heat flux density. Surface delamination, radial cracks, and tie rod failures have been observed in the outboard tungsten-coated CFC tiles, while bulk tungsten special lamellas were intentionally melted in dedicated experiments. These different types of damag…
