Magister Scientiae - MSc / The development of a deuterium-deuterium/ tritium-deuterium (D-D/ D-T) pulsed neutron generator based on the principle of the Plasma Immersion Ion Implantation (PI3) technique is presented, in terms of investigating development of a compact system to generate an ultra short burst of mono-energetic neutrons (of order 1010 per second) during a short period of time (< 20μs) at repetition rates up to 1 kHz. The system will facilitate neutron detection techniques, such as neutron back-scattering, neutron radiography and time-of-flight activation analysis. Aspects addressed in developing the system includes (a) characterizing the neutron spectra generated as a function of the target configuration/ design to ensure a sustained intense neutron flux for long periods of time, (b) the system was also characterised as a function of power supply operating conditions such as voltage, current, gas pressure and plasma density. / South Africa

Cette thèse porte sur l'endommagement laser à la surface de composants optiques en silice amorphe en régime nanoseconde. Ce phénomène est une modification irréversible du matériau. Dans le régime nanoseconde, l'endommagement laser de la silice est étroitement corrélé à la présence de défauts précurseurs qui sont une conséquence de la synthèse et du polissage des composants. Cette thèse propose des investigations sur l'endommagement laser par plusieurs longueurs d'onde simultanément. Afin de mieux appréhender ce phénomène dans ces conditions d'irradiation, trois études sont conduites. La première porte sur la phase d'amorçage des dommages. Les résultats expérimentaux obtenus dans les cas mono-longueur d'onde permettent de mettre en avant un couplage dans le cas multi-longueurs d'onde. Une comparaison de ces résultats avec un modèle théorique développé au cours de cette thèse permet d'améliorer la compréhension des processus fondamentaux liés à cette phase d'endommagement. Puis, des caractérisations morphologiques post mortem couplées à une métrologie précise des faisceaux laser permettent d'établir la nature ainsi que la chronologie des mécanismes conduisant à la formation des dommages. Le scénario théorique proposé est validé à travers différentes expériences. En dernier lieu, nous étudions la phase de croissance des dommages dans les cas mono et multi-longueurs d'onde. Une fois de plus, cette dernière configuration met en lumière un couplage entre les longueurs d'onde. Nous montrons la nécessité de prendre en compte les caractéristiques spatiales des faisceaux laser lors d'une session de croissance des dommages. / In this thesis, laser-induced damage phenomenon on the surface of fused silica components is investigated in the nanosecond regime. This phenomenon consists in an irreversible modification of the material. In the nanosecond regime, laser damage is tightly correlated to the presence of non-detectable precursor defects which are a consequence of the synthesis and the polishing of the components. In this thesis, we investigate laser damage in a multiple wavelengths configuration. In order to better understand this phenomenon in these conditions of irradiation, three studies are conducted. The first one focuses on damage initiation. The results obtained in the single wavelength configurations highlight a coupling in the multiple wavelengths one. A comparison between the experiments and a model developed during this thesis enables us to improve the knowledge of the fundamental processes involved during this damage phase. Then, we show that post mortem characterizations of damage morphology coupled to an accurate metrology allow us to understand both the nature and also the chronology of the physical mechanisms involved during damage formation. The proposed theoretical scenario is confirmed through various experiments. Finally, we study damage growth in both the single and the multiple wavelengths cases. Once again, this last configuration highlights a coupling between the wavelengths. We show the necessity to account for the spatial characteristics of the laser beams during a growth session.
