Student thesis: Phd


The STEFF spectrometer was used at the Neutron Time-of-Flight facility (n_ToF) at CERN in 2016 to perform a 30-day long experimental campaign of measurements of fission fragments and gamma rays produced in 235U fission for a wide range of incident neutron energies. A pipeline for reading, correlating and database deposition of the experimental data from this experimental campaign as well as for future STEFF campaigns at n_ToF has been constructed. The pipeline resulted in 70-fold data size reduction to an experimental database that can be fully processed in ~7 hours. The collected gamma-ray data acquired using NaI and LaBr3 detectors have been analyzed in the
