  1. 1. Detector Development, Source Characterization and Novel Applications of Laser Ion Acceleration

    Författare :Lovisa Senje; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Laser; Ion; Acceleration; Proton; Water; Sheath; Lifetime; Laser; Ion; Acceleration; Proton; Water; Radiolysis; Sheath; Detector; Fysicumarkivet A:2017:Senje;

    Sammanfattning : The main focus of the work presented in this thesis is on experimental studies oflaser acceleration of protons and other positive ions from solid targets. The topic is explored from three different angles: firstly, the development of diagnostics adapted to the ion pulses, secondly, the characterization of the source of the energetic particles and, finally, the application of laser-accelerated protons for time-resolved radiolysis of glass and water.

  7. 5. A Fast Pixelated Thermal-Neutron Detector

    Författare :Emil Rofors; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SoNDe; thermal-neutron detector; GS20 scintillator; Li-glass; H12700A MAPMT; position-dependent response; alpha-particle; proton; deuteron; neutron; ESS; SKADI;

    Sammanfattning : This thesis presents the study of a position-sensitive scintillation-based detector called the Solid-State Neutron Detector (SoNDe). SoNDe is being developed for cold- and thermal-neutron detection at the small-angle neutron scattering (SANS) instrument SKADI at the European Spallation Source (ESS), currently under construction in Lund, Sweden.
