"Beatriz Amorim, student at the Faculty of Sciences of the University of Lisbon, has defended her master's thesis. The work was carried out as part of LIP's NUC-RIA group. Congratulations to the new Master!"
Beatriz Amorim, a master's student in Engineering Physics at FCUL and a member of LIP's NUC-RIA group, successfully defended her master's thesis on 25 October, entitled ‘Assembly and commissioning of a high rate plastic scintillation detector for fission isomer studies’. This work was carried out in collaboration with the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany, and was supervised by Daniel Galaviz (FCUL/LIP) and Jianwei Zhao (GSI). The jury included Matjaž Vencelj (examiner, Jožef Stefan Institute) and Manuel Abreu (president of the jury, FCUL), as well as the supervisors.
The work consisted of assembling and studying a scintillator strip detector developed with the aim of measuring the lifetimes of fission isomers. This detector consists of a series of small plastic scintillators. Its main function is to associate the detection of implanted fission events with the nuclei identified and produced in the fragment separator (FRS). In this way, the detector makes it possible to accurately measure the half-life times of previously unknown fission isomers.
To carry out the project, Beatriz received a grant from the Marie Sklodowska-Curie programme of the International Atomic Energy Agency (IAEA), which funded her final year of her master's degree and complemented her stay in Germany for 2024, also supported by the GET_INvolved programme of the FAIR laboratory.
As soon as she finished her thesis, Beatriz began preparing for the University of York, where she will start her PhD in the field of nuclear instrumentation, focusing on the characterisation of a new charged particle detector, which will be integrated into the core of FAIR's R3B (Reactions with Relativistic Radioactive Beams) experiment.
Congratulations, Beatriz! And much success in the future!
