1. 1. Simulation-based discrimination of Crab pulsar models with XL-Calibur

   University essay from KTH/Fysik

   Author : Dennis Åkerström; [2024]
   Keywords : Astroparticle Physics; Astrophysics; Detector Physics; Simulation; Theoretical Physics; Engineering Physics; Pulsar models; Crab pulsar; Astropartikelfysik; Astropartikelfysik; Detektorfysik; Simulering; Teoretisk Fysik; Teknisk Fysik; Pulsar modeller; Krabbpulsaren;

   Abstract : Polarisation of X-ray light is being investigated with polarimeters to extend the borders of what can be observed. Distant compact objects, such as pulsars, that are to small on the sky to be analysed with imaging can be investigated by analysing the polarisation of the emitted light. This can reveal physics previously hidden by their small nature. READ MORE

3. 2. Characterization of neutron detection efficiency in a liquid organic scintillator

   University essay from

   Author : Ebba Wargh; Nadine Tabeshnia; [2023]
   Keywords : ;

   Abstract : Neutron detectors in the form of liquid organic scintillators are widely used for nuclear disarmament purposes. The main purpose of this thesis is to characterize the neutron detection efficiency of the organic liquid scintillator EJ-309 using Monte Carlo based simulations in the simulation program Geant4.

4. 3. Neutron Veto Inefficiency Studies with FLUKA for the LDMX Hadronic Calorimeter

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Jaida Raffelsberger; [2023]
   Keywords : Physics and Astronomy;

   Abstract : Dark matter accounts for about 85% of all matter in the Universe, yet its particle nature remains unknown. The Light Dark Matter eXperiment (LDMX) is a proposed fixed-target missing-momentum experiment that intends to probe the predominantly experimentally uncharted MeV-GeV mass range for "light dark matter".

5. 4. Silicon Drift Detector Simulations for Energy-Dispersive X-ray Spectroscopy in Scanning Electron Microscopy

   University essay from Stockholms universitet/Fysikum

   Author : Sebbe Blokhuizen; [2023]
   Keywords : X-ray spectroscopy; Silicon drift detector; Scanning Electron Microscopy; Detector Simulation;

   Abstract : Scanning Electron Microscopy combined with Energy Dispersive X-ray Spectroscopy (SEM-EDS) is a widely applied elemental microanalysis method. The integration of silicon drift detectors (SDDs) has notably enhanced EDS performance, enabling precise elemental identification due to its large sensitive area and low output capacitance.

6. 5. High spatial resolution study of local corrosion effects on BWR-fuel cladding : Using a combined method of GEANT4 and lwrChem

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Martin Nilsson Lind; [2023]
   Keywords : fission; zircaloy; corrosion; radiolysis; radiation; BWR; Monte Carlo; GEANT4; lwrChem;

   Abstract : The core of a BWR constitutes a highly complex radiational and chemical environment. Nuclear fission is utilized to generate power and as a consequence, large quantities of ionizing radiation are produced. Gamma and beta-particles along with neutrons have the sufficient ranges to escape the fuel rods and deposit energy in the reactor coolant. READ MORE
