The 2023 JET deuterium–tritium (D–T) experimental campaign (DTE3) achieved record fusion energy output (69 MJ), providing a unique 14.1 MeV neutron environment for irradiation studies. A range of ITER material samples were exposed in a Long-Term Irradiation Station (LTIS) within the JET nuclear environment to neutron fluxes up to 2 × 10¹³ n/…

Background: The emergence and growth of fusion technology enables investigative studies into its applications beyond typical power production facilities. This study seeks to determine the viability of medical isotope production with the neutrons produced in an example large fusion device. Using FISPACT-II (a nuclear inventory code) and a simulated …

Fusion performance in a tokamak-reactor strongly depends on the confinement of thermalised α-particles (Helium (He) ash) in the core plasma region. Consequently, the development of He particle transport models and their validation in present experiments is an important step towards a more accurate prediction of fusion power production in future de…

This paper presents a technical overview of AutoInspect, a ROS-based software system for robust and extensible mission-level autonomy. Over the past three years we have deployed AutoInspect on multiple platforms in a variety of environments, from forests to fusion reactors, for durations ranging from hours to weeks. The AutoInspect system combin…

Neutral Beam Injection (NBI) is a flexible auxiliary heating method for tokamak plasmas, capable of being efficiently coupled to the various plasma configurations required in the Tritium and mixed Deuterium-Tritium Experimental campaign (DTE2) on the JET device. High NBI power was required for high fusion yield and alpha particle studies and to …

Tungsten-based compounds are prized for exceptional properties crucial in nuclear fusion applications. Commonly cemented carbides can not be used in nuclear fusion applications due to the environmental, nuclear and high temperature limitations of cobalt and its alloys. This work proposes the use of small additions of low activation metals as alt…

A fast neutral lithium beam is used at JET for more than 30 years to measure profiles of electron density in the pedestal and scrape off layer. The diagnostic was not designed for tritium operation. In this paper, we describe the modifications which were required to allow operation in tritium (T) and deuterium-tritium (D-T ) fuelled pulses at JE…

The MAST-U Super-X divertor provides the opportunity to study fusion plasma exhaust in novel conditions. However, in order to study these conditions advanced diagnostics are required. Following the development of the MAST-U Multi-Wavelength Imaging (MWI) diagnostic, we present the installation of a multi-delay coherence imaging spectroscopy (CIS…

The fusion reaction between deuterium and tritium, D(T,n)4He is the main source of energy in future thermonuclear reactors. Alpha-particles (4He-ions) born with an average energy of 3.5MeV transferring energy to the thermal plasma during their slowing down, they should provide the self-sustained D-T

We report on a new ground-level neutron monitor design for studying cosmic rays and fluxes of solar energetic particles at the Earth’s surface. The first-of-its-kind instrument, named the NM-2023 after the year it was standardised and following convention, will be installed at a United Kingdom Meteorological Office observatory (expected complet…
