  1. 6. Experimental studies at CERN-nTOF of the 230Th(n,f) reaction

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Felicia Lapinski; [2020]
    Keywords : fission; neutron induced fission; fission cross section; fission fragment angular distribution; thorium;

    Abstract : This work investigates the feasibility to perform an experiment at CERN n_TOF to study the fission cross section and fission fragment angular distribution (FFAD) of the 230Th(n,f) reaction. An analysis of fission fragment energy losses in the experimental target resulted in a choice of target thickness of 0. READ MORE

  3. 7. Stars Eating Planets

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : John Wimarsson; [2020]
    Keywords : Earth and planetary astrophysics; planetary dynamics; planet-planet scattering; planet consumption; Physics and Astronomy;

    Abstract : In a phase of instability during the dynamical evolution of some multiple exoplanetary systems, exchange of angular momentum and/or energy through gravitational interactions between planets will lead to alterations of their orbital properties. In some cases, planetary orbits end up crossing, which leads to close encounters between two planets. READ MORE

  4. 8. Monte Carlo Simulations of Bowing Effects Using Realistic Fuel Data in Nuclear Fuel Assemblies

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Marcus Westlund; [2019]
    Keywords : bowing effects; fuel assembly perturbations; nuclear; serpent; monte carlo;

    Abstract : Deformations of nuclear fuel assemblies have been observed in nuclear power plants since the mid-90s. Such deformations are generally called bowing effects. READ MORE

  5. 9. Implementation and characterization of Silicon detectors for studies on neutron-induced nuclear reactions

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Leo Lehtilä; [2019]
    Keywords : Silicon detector; Silicon telescope; Ultra-thin silicon detector; Energy resolution; Radioactive source; Am-241; Cf-252; Fission Fragments; Alpha Particles;

    Abstract : Energy resolution characteristics of silicon surface barrier detector signals amplified by different preamplifiers and spectroscopic amplifiers have been studied. The characterization has been done using alpha particles from an 241Am source and spontaneous fission fragments from two Cf sources. READ MORE

  6. 10. 2D Neutron Imaging with 10B-Based Multi-Blade Detector

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Tõnu Ilves; [2018]
    Keywords : thermal; neutron; imaging; 2D; Multi-Blade; detector; boron; boron-10; nuclear physics; multi wire proportional chamber; digitizer; ESS; European Spallation Source; surface study; reflectometry; Physics and Astronomy;

    Abstract : In the field of thermal-neutron imaging, the Multi-Blade detector concept and design, being developed for the upcoming European Spallation Source in Lund, Sweden, is unique. The current report presents, for the first time, the neutron-imaging capabilities of a boron-10-based Multi-Blade thermal-neutron detector, measured at a reflectometry instrument at Rutherford Appleton Laboratory in Oxfordshire, England under high spallation neutron flux.
