1. 11. Characterization of a Bismuth germanate Anti-Compton Scattering Shield for use with a Germanium COMPEX detector module

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

   Author : Samuel Dawes; [2022]
   Keywords : COMPEX; Lundium; BGO; ACS; gamma-ray spectroscopy; Physics and Astronomy;

   Abstract : The scope of this work is to help determine the functional improvement brought on by introducing a Bismuth germanate (BGO) Anti-Compton Scattering (ACS) shield system to a germanium COMPEX detector module. The COMPEX germanium detector module is already an extremely useful addition in examining gamma-ray spectroscopy. READ MORE

3. 12. Measuring the vertical muon intensity with the ALTO prototype at Linnaeus University

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Author : Magnus Norén; [2021]
   Keywords : Muon Intensity; ALTO; CoMET; Cosmic Rays; VHE Gamma Rays; Extensive Air Shower; Water Cherenkov Detector; Scintillation Detector; Monte Carlo Simulation; GEANT4;

   Abstract : ALTO is a project, currently in the research and development phase, with the goal of constructing a Very High Energy (VHE) gamma-ray observatory in the southern hemisphere. It will detect the particle content reaching the ground from the interactions of either VHE gamma rays or cosmic rays in the atmosphere known as extensive air showers. READ MORE

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

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

   Author : Armando Javier Morales Urrutia; [2021]
   Keywords : Physics and Astronomy;

   Abstract : 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. READ MORE

5. 14. Constraints on the High-Energy Gamma-Ray Spectrum of Nearby Star-Forming Galaxies

   University essay from Stockholms universitet/Fysikum

   Author : Oskar Svenborn; [2021]
   Keywords : Gamma-ray emission; High-Energy astrophysics; Star-Forming Galaxies; Star formation; Cosmic rays; Fermi-LAT.;

   Abstract : The nature of high-energy gamma-ray emission from Star-Forming Galaxies is of utmost importance for understanding both the origin of Cosmic Rays and the high-energy processes that shape galaxy formation. Observations from the gamma-ray telescope Fermi-LAT have detected gamma-ray emission from a handful of nearby Star-Forming Galaxies. READ MORE

6. 15. High-Redshift Gamma-ray Bursts as seen by SVOM/ECLAIRs

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Miguel Llamas Lanza; [2021]
   Keywords : Gamma-ray Bursts; GRBs; compact objects; high energy; ECLAIRs; SVOM; high redshift; T90; detection biases;

   Abstract : Gamma Ray Burst (GRB) are very bright cosmological explosions signalling the catastrophic formation of a black hole. Therefore, they act like real light beacons that could be detected through-out the Universe and be used as probes to study the contents and phases of the early Universe. However, only a handful sample is known so far. READ MORE
