Développement d'une cible polarisée de pur HD : Analyse et distillation du HD Diffusion compton virtuelle résonante sur le nucléon à TJNAF
Résumé
The first part describe my work on the frozen spin target project HYDILE. This target has to be made of very pur HD (hydrogen deuterium) better than 99,95%. However commercial HD is never found with a concentration better 98%. The goal was, then, to build an HD distillation facility which could produce pur HD. We describe, in this thesis, the design of the distillator and the implementation of a quadrupole mass spectrometer to monitor the HD purity during the distillation process. The second part of the thesis concerns the analysis taken at the electron accelerator facility TJNAF(Virginia,USA). We look at the electroproduction of Delat resonances involving Deep Virtual Compton Scattering(Delta VCS). The interpretation of this reaction in terms of GPDs can provide new insights to the nucleon structure. We focus on the measurement of the beam spin asymetrie which comes from the interference of the Bethe Heitler process with the Delta VCS.
