DOSADO

The DOSADO (DOSimétrie Applications et DOnnées nucléaire) group is composed of about eight people (5 permanent staff and about 3 PhD students or postdoctoral researchers).

The group’s first research domain is closely connected to the Neutrons For Science (NFS) facility, which benefits of the high intensity proton, deuteron and alpha beams delivered by the SPIRAL2 facility. The group conducts experimental research ranging from fundamental to applied physics, with activities focused on nuclear data measurements, neutron-induced fission, radiotherapy, and dosimetry.

Within this framework, the first research activity involves a collaboration with the Uppsala University (Sweden) focused on measuring double-differential cross sections of light charged particles in neutron induced reactions using the MEDLEY setup. These measurements contribute to improve the nuclear reaction models and fed the nuclear databases. These bases are essential for the development of nuclear technology (fission and fusion) and in electronics (Single Event Upset).

The second activity addresses the study of fission induced by fast neutrons (>10 MeV) in direct kinematics using low-pressure detectors. This research, carried out in collaboration with CEA/DRF/IRFU, focuses on measuring the mass and kinetic energy of fission fragments with the FALSTAFF setup, enabling a precise investigation of the fission process. Fission studies represent a major research program at NFS and within the group, encompassing long-term projects, multiple measurement campaigns, and ongoing instrumentation developments.

The third research domain focuses on medical applications related to radiotherapy with two main activities. The first concerns radioisotope production for targeted radionuclide therapy, including high-power target design, precise determination of production yields, and characterization of radioactive contaminants (measurements at NFS and instrumental developments). The second activity is dedicated to developing dosimetry methods and instruments for hadrontherapy and targeted radionuclide therapy, at both clinical and radiobiological levels. This activity relies on interdisciplinary collaborations and includes experiments in radiobiology laboratories and treatment centers.

In addition to its research activities, the group contributes to the coordination and support of experiments proposed to the PAC and performed at the NFS facility.
