Actualités
- L’ILL a élaboré une stratégie scientifique pour la décennie à venir, afin de tirer parti des améliorations apportées aux installations grâce au programme Endurance et de servir de guide pour l’allocation des ressources, renforçant et démontrant ainsi le rôle majeur de l’ILL dans le paysage européen des neutrons. Le document dans lequel est présentée la stratégie est disponible ici.
- Les Journées françaises de la Diffusion des Neutrons (JdN 2025) ont eu lieu au lac d’Annecy du 2 au 6 juin. Avec 70 participants au total c‘était un cocktail très intéressant d’exposés scientifiques et techniques. Deux sessions spéciales ont été organisées, l’une sur les « handicaps invisibles » et l’autre sur les « Infrastructures de recherche: synergies, complémentarités, analyse des données, modes d’accès ». Cette dernière a réuni des collègues issus d’installations neutroniques (ESS, ILL, 2FDN, LLB), d’autres infrastructures de recherche(ESRF, PSI, CERN, EMFL), ainsi que des experts thématiques issus de la communauté scientifique (EMBL, battery hub, FAIR data, AI4science), qui ont présenté de courtes interventions et échangé activement avec les participants des JdN 2025. Le CA de la SFN remercie vivement les organisateurs des JdN 2025 pour ces journées particulièrement riches en exposés et en échanges !
- Le prix de thèse 2025 de la SFN a été décerné à Valentin Czamler pour ses travaux portant sur l’utilisation de clathrates hydratés pour la production de neutrons très froids. Ses travaux font l’objet de l’actualité scientifique de ce bulletin. La cérémonie de remise du prix a eu lieu pendant les JdN.
- Les FANs de la 2FDN se sont déroulées du 24 au 26 juin à l’ILL à Grenoble. Les travaux pratiques ont eu lieu sur les CRG français : IN12 et D1b pour les groupes de matière dure et magnétisme, SAM et SHARPER pour les groupes de matière molle et biophysique.
Prochaines dates limites :
- ILL – appel à propositions : 15 septembre 2025
- 2FDN – appel à propositions : 15 octobre 2025
Actualité scientifique du mois
Deuterated Clathrate Hydrates as a Novel Moderator Material for Very Cold Neutrons
Producing more intense very cold neutron beams could enhance both neutron scattering techniques and precision experiments in particle physics using slow neutrons. Clathrate hydrates containing THF-d and O₂ offer new moderation pathways via localized low-energy modes. Neutron scattering experiments confirmed the hydrate structure as well as vibrational and magnetic contributions to neutron thermalization.
