Abstract The JET 2019–2020 scientific and technological programme exploited the results of years concerted engineering work, including ITER-like wall (ILW: Be W divertor) installed in 2010, improved diagnostic capabilities now fully available, a major neutral beam injection upgrade providing record power 2019–2020, tested technical procedural preparation for safe operation with tritium. Research along three complementary axes yielded wealth new results. Firstly, plasma delivered scenarios...
Abstract In 2021 JET exploited its unique capabilities to operate with T and D–T fuel an ITER-like Be/W wall (JET-ILW). This second major campaign (DTE2), after DTE1 in 1997, represented the culmination of a series enhancements—new fusion diagnostics, new injection capabilities, refurbishment plant, increased auxiliary heating, in-vessel calibration 14 MeV neutron yield monitors—as well as significant advances plasma theory modelling community. DTE2 was complemented by sequence isotope...
The 2014–2016 JET results are reviewed in the light of their significance for optimising ITER research plan active and non-active operation. More than 60 h plasma operation with first wall materials successfully took place since its installation 2011. New multi-machine scaling type I-ELM divertor energy flux density to is supported by principle modelling. relevant disruption experiments modelling reported a set three mitigation valves mimicking setup.

The objective of thermonuclear fusion consists producing electricity from the coalescence light nuclei in high temperature plasmas. most promising route to envisages confinement such plasmas with magnetic fields, whose studied configuration is tokamak. Disruptions are catastrophic collapses affecting all tokamak devices and one main potential showstoppers on a commercial reactor. In this work we report how, deploying innovative analysis methods thousands JET experiments covering isotopic...
The principle needs of ITER with regard to nuclear analysis can be divided into the broad categories safety and licensing, plant operation, decommissioning although there is much overlap interdependence within these categories.This paper reviews status methods applied date recommends future strategy which should adopt address continuing requirements responsibilities. This done by consideration application radiation transport codes, creation an reference neutronics model, a results database,...
An accurate calibration of the JET neutron diagnostics with a 14 MeV generator was performed in first half 2017 order to provide reliable measurement fusion power during next deuterium–tritium (DT) campaign. In meet target accuracy, chosen has been fully characterized at Neutron Metrology Laboratory National Physical (NPL), Teddington, United Kingdom. The present paper describes measurements energy spectra obtained using high-resolution single-crystal diamond detector (SCD). measurements,...
Due to the high neutron yield and large plasma size many ITER parameters such as fusion power, power density, ion temperature, fast energy their spatial distributions in core can be measured well by various diagnostics. Neutron diagnostic systems under consideration development for include radial vertical cameras (RNC VNC), internal external flux monitors (NFMs), activation spectrometers. The two-dimensional source strength spectral measurements provided combined RNC VNC. NFMs need meet...

The measured D–D neutron rate of neutral beam heated JET baseline and hybrid H-modes in deuterium is found to be between approximately 50% 100% the expected from TRANSP code, depending on plasma parameters. A number candidate explanations for shortfall, such as fuel dilution, errors penetration effectively available power have been excluded. As dominated by beam–plasma interactions, 'neutron deficit' may caused a yet unidentified form fast particle redistribution. Modelling, which assumes...
