One of the options developed to discriminate different particles with similar energy is the composition of several stage detectors, usually called Telescope Detection Systems. In this work four Single Sided Silicon Stripped detectors with thicknesses of ≈20 µm have been characterized to improve their response as ∆E in Telescope detection systems. The characterization resulted in the precise determination of the detector thickness throughout its surface. Two different methods were applied to achieve this goal. Maximum deviations of up to 35 % were observed. This charactererization will allow for a better resolution of the system and a clearer discrimination of the reaction products. Several steps were undertaken during the analysis. The angular calibration of the setup was performed using the scattering reaction 10Be + 197Au at energies below the Coulomb barrier. The energy calibration of the E stage was performed using radioactive sources and corrected for high energies by applying a gain match procedure that allowed a tighter constrain in the event selection. The energy calibration of the thin detectors, done with low energy nuclear reactions and radioactive sources, had to consider the struggling of particles in the dead layers of the material to correctly determine the energy deposited by incident particles in the active detector layer. The results of this work will allow a more precise analysis of the reaction data on the exotic nucleus 10Be on the magic nucleus 120Sn, measured for the first time at energies around the Coulomb Barrier, at the LNS laboratory in Catania (Italy).Galaviz Redondo, DanielFernández, Juan PabloRepositório da Universidade de LisboaBarba, Francisco Maria Santos Lima Geraldes2022-07-05T17:17:16Z202220222022-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10451/53658enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-08T16:59:41Zoai:repositorio.ul.pt:10451/53658Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T22:04:36.861477Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
