    Sammanfattning : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. LÄS MER

  3. 2. Feasibility of HALEU-loaded Breed-and-Burn Molten Salt Fast Reactor without Online Actinide Treatment

    Master-uppsats, KTH/Fysik

    Sammanfattning : Molten Salt Fast Reactors (MSFRs) have prominent advantages such as fuel breeding, nuclear waste transmutation, and inherent safety. They are the only liquid-fueled nuclear reactors currently receiving significant attention as fourth-generation advanced nuclear systems. LÄS MER

  4. 3. Calibration of a Fast Neutron Time-of-Flight System

    Magister-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Armando Javier Morales Urrutia; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Future experiments with thermal neutrons at neutron facilities may encounter fast neutrons as sources of background. Understanding fast neutron behavior on an event-by-event basis in a detector is important for these complementary thermal neutron experiments. One way to study fast neutron events is by performing a time-of-flight measurement. LÄS MER
