The APRENDE Experimentalists-Evaluators Workshop, a pivotal milestone uniting the New Nuclear Data measurements and Nuclear Data evaluation work packages communities (WP2 & WP4), took place on February 26 and 27, 2025, at the Institut Pluridisciplinaire Hubert Curien (IPHC) in Strasbourg, France.
Over two days, participants engaged in a series of sessions focusing on decay data, fission yields, and cross-section measurements. These sessions fostered in-depth discussions, enhancing mutual understanding between experimentalists and evaluators.
The workshop featured presentations from experts Dr Pascal Romain (CEA Bruyeres), Dr. Stephane Hilaire (CEA Bruyeres), Dr. Gilles Noguere (CEA Cadarache) Dr. Grégoire Kessedjian (CEA Cadarache), Dr. Maëlle Kerveno (CNRS IPHC), Dr. Emilio Mendoza (CIEMAT), Dr. Daniel Cano Ott (CIEMAT), Dr. Jean-Eric Ducret (GANIL), Dr. Adina Coman (IFIN-HH), Dr. Kenichi Tada (JAEA), Dr. Dimitri Rochman (Paul Scherrer Institute), Dr. Fiorito Luca (SCK CEN), Dr. Stefan Lalkovski (Sofia University), Dr. Lydie Giot (Subatech IMT Atlantique), Dr. Muriel Fallot (Subatech-Université de Nantes), Dr. Nikolas Patronis (University of Ioannina), and Dr. Ali Al-Adili (Uppsala University).
The highlights of the workshop are:
Improved exchange of needs and ideas between both communities of evaluators and experimentalists. Experimentalists expressed their interest to know more about the evaluation work, the necessary ingredients entering in the calculations of evaluated nuclear data, and in return, evaluators asked about information not systematically presented in general publications, such as experimental specificities and constrains.
The need for boosted education and hands-on. It was recognized from both the experimentalist and evaluator communities that an enhanced understanding would come from performing common exercises (reduction of experimental data, or model calculations) which would generate questions, exchanges, interactions and finally better understanding and knowledge.
It was also recognized that there is a need for prioritization of work and long-term support. Given the limited current resources, both communities would gain to establish lists of priorities for measurements and theoretical calculations, possibly supported by systematized and standardized approaches.
A highlight of the event was the networking dinner on February 26, providing attendees with an opportunity to connect informally and discuss collaborative prospects. The workshop is a first step towards continuous dialogue and collaboration in advancing nuclear data research.
