Demonstration of Super-X divertor exhaust control for transient heat load management in compact fusion reactors

B. Kool, K. Verhaegh, Gijs Derks, J.T.W. Koenders et autres

Abstract Nuclear fusion could offer clean, abundant energy. However, managing the power exhausted from the core fusion plasma towards the reactor wall remains a major challenge. This is compounded in emerging compact reactor designs promising more cost-effective pathways towards commercial fusion energy. …

Deuterium and tritium density determination at JET using neutron diagnostics

J. Eriksson, S. Conroy, G. Ericsson, Anders Hjalmarsson et autres

Abstract The fuel ion densities of tritium (T) and deuterium (D) are important parameters for reactor control in fusion experiments. The fuel ion densities typically need to be determined for a wide range of experimental conditions, anywhere between pure deuterium plasmas with …

Development and performance of the thin-foil proton recoil spectrometer for ITER plasma diagnostics

J. Dankowski, J. Bielecki, J. Błądek, S. Conroy et autres

High Resolution Neutron Spectrometer (HRNS) is one of the essential plasma diagnostics of ITER, whose operational role is the neutronic measurement of the n t /n d ratio in a plasma core. Coexisting with the other ITER diagnostics makes it a powerful …

Estimating the neutron yield in a deuterium–tritium plasma with the JET neutron camera

L. Hägg, S. Conroy, G. Ericsson, Z. Ghani et autres

The JET neutron camera is used to monitor a 2D profile of the neutron emission from the plasma, using 19 sightlines with plastic scintillators suited for measuring neutrons from the D + T → n + 4He (DT) reaction. This paper describes …

Plasma rotation and thermonuclear neutron emission estimates in JET deuterium tritium plasmas from neutron spectroscopy

L. Hägg, J. Eriksson, S. Conroy, G. Ericsson et autres

Abstract Data from the magnetic proton recoil spectrometer (MPRu) high-resolution neutron spectrometer has been used to estimate two fusion plasma quantities, the plasma rotation and the thermonuclear neutron emission. This paper presents a framework for this method and the current results for …

Human-centred test and evaluation of military AI

S. Conroy, Adam Hepworth, Manoj Harjani

The REAIM 2024 Blueprint for Action states that AI applications in the military domain should be ethical and human-centric and that humans must remain responsible and accountable for their use and effects. Developing rigorous test and evaluation, verification and validation (TEVV) frameworks …

Learning from each other: Cross-cutting diagnostic development activities between magnetic and inertial confinement fusion (invited)

M. Gatu Johnson, D. J. Schlossberg, Brian Appelbe, J. Ball et autres

Inertial Confinement Fusion and Magnetic Confinement Fusion (ICF and MCF) follow different paths toward goals that are largely common. In this paper, the claim is made that progress can be accelerated by learning from each other across the two fields. Examples of …

First measurement in a magnetic confinement fusion experiment of the H 3 + H 3 → He 5 + n intermediate two-body resonant reaction

B. Eriksson, S. Conroy, G. Ericsson, J. Eriksson et autres

We report on the first experimental measurements made at a magnetic confinement fusion device of the tritium(T)-tritium(T) reaction T + T → He 4 + 2 n indicating the presence of the intermediate two-body resonant reaction T + T → He 5 …

A control oriented strategy of disruption prediction to avoid the configuration collapse of tokamak reactors

A. Murari, Riccardo Rossi, T. Craciunescu, J. Vega et autres

The objective of thermonuclear fusion consists of producing electricity from the coalescence of light nuclei in high temperature plasmas. The most promising route to fusion envisages the confinement of such plasmas with magnetic fields, whose most studied configuration is the tokamak. Disruptions …

Overview of the EUROfusion Tokamak Exploitation programme in support of ITER and DEMO

E. Joffrin, M. Wischmeier, M. Baruzzo, A. Hakola et autres

Abstract Within the 9th European Framework programme, since 2021 EUROfusion is operating five tokamaks under the auspices of a single Task Force called ‘Tokamak Exploitation’. The goal is to benefit from the complementary capabilities of each machine in a coordinated way and …

The single crystal diamond-based diagnostic suite of the JET tokamak for 14 MeV neutron counting and spectroscopy measurements in DT plasmas

D. Rigamonti, A. Dal Molin, A. Muraro, M. Rebaı̈ et autres

Abstract The Joint European Torus (JET) has recently conducted its second deuterium–tritium (DT) experimental campaign DTE2, providing unique opportunity for studying both physics and engineering aspects of nuclear fusion plasmas. This also allowed the exploitation of new diagnostics and technologies that were …
