1. 21. Simulation of Anti-Compton Shield Augmentation to the Lundium Decay Station Using Geant4

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

   Author : Daesung Cho; [2019]
   Keywords : Lundium; Geant4; Anti-Compton shield; gamma spectroscopy; Physics and Astronomy;

   Abstract : The Lundium decay station improves on the existing TASISpec spectrometer used to investigate the nuclear structure of superheavy nuclei by photon- and charged particle-spectroscopy. This thesis aims to explore the potential benefits of the future Lundium station with the augmentation of anti-Compton shields com- posed by a set of BGO scintillator bars. READ MORE

3. 22. Identification of Neutrons Using Digitized Waveforms

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

   Author : Rasmus Kjær Høier; [2019]
   Keywords : Digitizer; neutron; gamma-ray; pulse-shape discrimination; CNN; convolutional neural network; charge comparison; time of flight; source-testing facility; STF; Physics and Astronomy;

   Abstract : The advantages of performing neutron-tagging measurements using a waveform digitizer are explored. An existing analog setup consisting of modular crate electronics at the Source-Testing Facility at the Division of Nuclear Physics in Lund, Sweden has been digitally replicated. READ MORE

4. 23. Design and Evaluation of a 3D Printed Ionization Chamber

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Caroline Boström; Olivia Messler; [2019]
   Keywords : 3D printing; Ionization chamber; Gas-filled detectors;

   Abstract : Ionizing radiation is often used within medicine for diagnosis and treatments. Because ionizingradiation can be harmful to the body, it is important to know how it affects the tissue. Dosimetryis the study of how ionizing radiation deposits energy in a material. READ MORE

5. 24. Software Development and Qualification Testing of a CubeSat X-ray Monitor

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Marcus Persson; [2019]
   Keywords : embedded software; cubesat; software; firmware; cubes; mist; x-ray; fpga; asic; weeroc;

   Abstract : The CUBES (CUbesat x-ray Background Explorer using Scintillators) is a payload on the KTH student satellite MIST (MIniature STudent satellite) to evaluate Silicon Photo-multiplier technology and new scintillators such as GAGG (Gadolinium Aluminium Gallium Garnet, Gd3Al2Ga3O12) for future use in hard X-ray polarisation studies of Gamma-Ray Bursts. CUBES itself is designed to study the MIST in-orbit radiation environment by using a detector which is comprised of a silicon photomultiplier coupled to different scintillator materials. READ MORE

6. 25. Studies of the orbital background noise and the detector characteristics for the MeVCube mission

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Eleni Athanasiou; [2019]
   Keywords : space instrumentation; gamma-ray instrumentation; MeVCube; space environment effects; orbital background noise; detector characteristics; signal generation; weighting potential simulations; electric field simulations;

   Abstract : A space camera is a promising candidate to address the non-stop rising interest for astrophysics research in the Compton regime. The MeVCube mission is intended to be launched in 2022, hosting an on-board Compton Camera. READ MORE
