Développement d'un système d'identification pour SPIRAL et test d'une cible d'uranium liquide dans le cadre du projet PARRNe

Abstract : In its first part, this research thesis addresses an important issue of the SPIRAL project: the study and realisation of a system of identification of radioactive beams at low energy. The objective is to characterise without any ambiguity radioactive beams emitted by the target-source set. The identification method is based on radioactive decays. After a descriptive presentation of radioactive beams and of their production mode, the author presents the GANIL laboratory and the SPIRAL project. This project is described in terms of beam production, identification, acceleration and control. The author then presents the different methods of measurement of the intensity of radioactive beams, and justifies the choice of the decay-based measurement method. He gives a general presentation of the identification system with a description of equipment used for the detection: germanium-, plastic-, and silicon-based sensors, and a tape drive. Different identification modes are also presented. In the next part, the author presents the general system operation structure: command and control of the detection equipment, acquisition, identification server, graphic interface. The last part presents the research and development program implemented in Orsay to produce neutron-rich radioactive ion beams. Some experiments of the PARRNe project are analysed and described, notably one which is based on a first time use of a liquid uranium target under beam
