Development of the Medley setup for NFS Main goal: perform accurate measurements of cross-sections in neutron-induced reactions . To be used at neutron research facility NFS (Neutrons For Science) at GANIL (Caen, France). Development and upgrade of the detection setup “Medley” , for different projects: Commissioning of the NFS neutron beam. LIONS ( L ight ION production S tudies). Reactor aging FISHES ( FIS sion vs H ydrogen E lastic S cattering). Reactor and criticality physics The renovated Medley chamber will be sent to NFS by the end of 2019 The ongoing development of PPACs ( P arallel P late A valanche C ounters) and of the general setup led to different publications and student projects : D. Tarrío et al ., “Characterization of PPACs’ time resolution for fission studies” . Presented at the Int. Conf. On Nuclear Data 2019, Beijing (China). S ubmitted to EPJ Web of Conf. (2019). L. Lehtilä , “Implementation and characterization of Silicon detectors for studies on neutron-induced nuclear reactions”, M.Sc. Thesis, 2019. K. Nakano , “Measurement of first Townsend coefficient of C3F8 for characterization of PPAC”, internal report (2018). Visiting Ph.D. student from Kyushu University (Japan). Several projects for undergraduate students. A PPAC detector
Medley -> NFS@GANIL Stephan Pomp Goal: Use the Medley setup at the Neutrons For Science (NFS) facility at GANIL (Caen, France): Perform studies of the fission process and light-ion production (dosimetry, gas production, etc.). Status: After many years of delay NFS finally starts commissioning during 2020. Medley has been dismantled, partly adjusted and renovated for NFS, cleaned, etc., and is ready for shipping. Next: Medley will be shipped to NFS end of Nov. Installation and first use in the commissioning is planned for Spring 2020. Main compontents of Medley: ready to be packed for shipping

Nuclear Safeguards – Research Sophie Grape , Erik Branger, Zsolt Elter, Vaibhav Mishra, Ane Håkansson, Li Pöder Balkeståhl • Erik Branger defended his thesis October 12, 2018 and currently is postdoc in the research group. • Viabhav Mishra is a new Ph.D. student within safeguards. His research focus lies on verification of spent fuel prior to encapsulation and novel technical safeguards approaches for Gen IV. • The research has during the last year addressed verification of non-regular fuels and the use of quivers. • The work with machine learning techniques continues now in collaboration with SCK•CEN in Belgium.
Nuclear Safeguards – Education Sophie Grape , Erik Branger, Zsolt Elter, Vaibhav Mishra, Ane Håkansson, Li Pöder Balkeståhl • We have, within a Horizon2020-project, offered the so-called course in safeguards (Feb 4-8 in Mol, November 11-15 in Jülich) • Collaborators are: SCK•CEN, FZJ and JRC Ispra. • In addition to the course, four workshops are offered.
