Characterization of scintillators for ion detection dagnostics in nuclear fusion reactors. (Trabajo Fin de Máster Inédito). Universidad de Sevilla, Sevilla.https://hdl.handle.net/11441/132745Abstract Scintillator materials are used for ion detection diagnostics in nuclear fusion devices. These diagnostics obtain information from the plasma in a fusion device, for example, in a tokamak. Scintillators working principle is based on the emission of visible light pho- tons by a scintillation material when irradiated with ions. As the currently used material, known as TG-Green, is not commercially available anymore, a search of scintillation ma- terials is made. The Tandem accelerator at ‘Centro Nacional de Aceleradores’ (CNA) is used to characterize the scintillation materials when irradiated with ions. Furthermore, a deposition technique is developed in order to create scintillator screens for their char- acterization, and for their use in different ion diagnostics. The present work proves the sedimentation technique is appropriate for the deposition of scintillators for ion diagnos- tics in fusion devices. Even though the literature showed other scintillators as optimal candidates, the experimental results have shown that, in terms of efficiency, the material TG-Green presents the highest absolute values compared with the analyzed materials.application/pdf67 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccess
