1. 1. Development of Radon Detectors for Earthquake Prediction

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Alma Partos; Astrid Schöldström; [2023]
   Keywords : Radon; earthquake; gamma ray spectroscopy;

   Abstract : The purpose of this project is to simulate the detection of γ-ray spectra emitted by radon isotopes and their daughters. This is done as a contribution to the development of radiation detectors to be used in a research project investigating the possibility of using increased amounts of the radioactive gas radon as an earthquake precursor.

4. 3. Data Reduction and Analysis with the MPRu instrument for Neutron Emission Spectroscopy at JET

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Steven Hendrik Bijl; [2023]
   Keywords : Fusion; JET; MPRu;

   Abstract : This research project centres on advancing data analysis techniques using the Magnetic Proton Recoil Upgrade Neutron Spectrometer (MPRu) for neutron emission spectroscopy during the deuterium tritium experimental campaign (DTE2) at the Joint European Torus (JET). The study aimed to address three pivotal questions, each with implications for optimizing data accuracy, quality, and utility. READ MORE

5. 4. Monte-Carlo simulations of an AmBe neutron source

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Josefine Sjöberg; [2021]
   Keywords : Serpent; neutron; gamma; radiation dose; AmBe source; polyethylene;

   Abstract : The Department of Physics and Astronomy in Uppsala is planning to construct a source-based neutron irradiation facility at Ångströms laboratory. The purpose of this facility will, as of now, mainly be for students and employees to conduct scientific experiments and to calibrate the university's neutron scintillator detectors. READ MORE

6. 5. Optical characterisation of AAO/CsPbBr3 perovskite nanocomposites

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

   Author : Klára Nováková; [2021]
   Keywords : perovskite; scintillator; optoelectronics; semiconductor; X-ray detection; Physics and Astronomy;

   Abstract : Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices.
