Développement d'une méthode de type 'velocity map imaging' pour la mesure de sections efficaces d’émission d'électrons par des molécules d'intérêt biologique en collision avec des ions
Autor: Sens, Nicolas
Publikováno v: Physique [physics]. Normandie Université, 2020. Français. ⟨NNT : 2020NORMC213⟩
In the last decades, ion collision with biologically relevant molecules has received increasing interest due to applications in radiation biology. The aim of this PhD is the development of a new crossed-beam experimental set-up dedicated to the measu

Development of a methodology to exploit nuclear data in the unresolved resonance range and the impact on criticality safety and reactor applications
Autor: Jeannesson, Clément
Publikováno v: Nuclear Theory [nucl-th]. Université Paris-Saclay, 2020. English. ⟨NNT : 2020UPASP074⟩
Neutronics computations are widely used in reactor physics and criticality calculations to ensure the safety and the exploitation of nuclear facilities. They rely on nuclear data which describe neutron-matter interactions. Among them, cross sections
