The completed experiments include the following achievements:
• The Medley setup was used to measure double differential cross sections for light ion production on chromium and iron at the new Neutrons for Science facility at GANIL, Caen by a collaboration of Uppsala University.
• The plasma delay time effect of the timing of PIPS detectors for the VERDI spectrometer was measured at the LOHENGRIN fission fragment spectrometer of ILL by a collaboration from JRC Geel, Uppsala, Bucharest, Edinburgh and Manchester.
• The inelastic neutron scattering on 238-U has been studied with the ν- ball 2 at the LICORNE facility by a collaboration from Surrey, Darmstadt, Strasbourg and Bucharest.
• Several novel neutron detection systems were studied and their response function determined at PTB Braunschweig, HISPANOS Seville, and the BR1 research reactor at SCK CEN Mol.
The completed education and training projects included important work on
• Preparation and building of the two arm fission spectrometer VERDI with double Energy and velocity measurement at JRC Geel
• Neutron-induced fission measurements of 243-Am at CERN n_TOF
To also introduce new students to the field of nuclear data four international schools were organized by ARIEL partners with educational experience:
• Nuclear data: the path from the detector to the reactor calculation, CIEMAT, Madrid (24 students) February 21- March 04 2022
• Hands-on school on the production, detection and use of neutron beams, University of Seville (24 students) September 21-30, 2022
• Hands-on school on nuclear data from Research Reactors, Centre for Energy Research & Institute of Nuclear Techniques, and Budapest University of Technology and Economics, in Budapest, Hungary (24 participants) September 25-29, 2023
• Lab course in Reactor Operation and Nuclear Chemistry, Johannes Gutenberg-University Mainz, Germany, Research Reactor TRIGA, (10 participants) November 19-24, 2023
The ARIEL project started with a kick-off meeting in Brussels, September 2019. The progress of the project was presented and discussed in two progress meeting and scientific workshops, the first was organized as a joint online meeting together with the SANDA project in March 2022 and the second one, a year later in person at NPL, Teddington, UK.
The final meeting of the ARIEL project took place at IJCLab in Orsay, France, January 2024
From all completed experiments and education and training projects up to now 23 peer reviewed publications were published. The ARIEL project and supported research was presented on international conferences, e.g. the International Conference on Nuclear Data for Science and Technology July 21-29,2022 and the 10th edition of the Euratom research and training conferences on fission safety of reactor systems (FISA 2022). The completed experiments will continue to lead to new publications and nuclear data sets also after the end of the ARIEL project.
