1. 1. Optimization of Gammasphere Data Following the Nuclear Reaction 36Ar + 24Mg → 60Zn∗

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Författare :Paul Böhm; [2023]
   Nyckelord :re-calibration; Gammasphere; 54Fe; Physics and Astronomy;

   Sammanfattning : The experiment at Argonne National Laboratory aimed to study the fusion-evaporation reaction following the collision of a high-energy particle beam of 36Ar with a stationary target of 24Mg. This paper outlines the creation and implementation of an automated re-calibration procedure for the high-purity Germanium detectors comprising the Gammasphere array used for γ-ray spectroscopy in this experiment.

3. 2. Determination of the source strength of an AmBe neutron source and design of flexible holder system for accurate measurements of ionising radiation

   L2-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Mathilde Ragot; [2022]
   Nyckelord :neutron source nuclear physics;

   Sammanfattning : The goal of this project was to determine the source strength of an Americium-Beryllium neutron source by irradiating metal foils of different elements. The irradiated foils were then placed on a High Purity Germanium detector and γ-decay from the decay of the neutron induced reaction products was observed and used to deduce the neutron flux.

4. 3. Test and Calibration of CUBES: a CubeSat X-ray Detector

   Master-uppsats, KTH/Fysik

   Författare :Caroline Holmberg; [2022]
   Nyckelord :Applied Physics; Astroparticle Physics; Tillämpad fysik; Astropartikelfysik;

   Sammanfattning : CUBES is an X-ray detector that will be placed aboard the KTH 3U CubeSat mission, MIST. Its purpose is to detect high energy X-rays as well as to test various components in a space environment. Two CUBES will be placed on the satellite. Each CUBES consists of a printed circuit board (PCB) with three multi pixel photon counters (MPPCs). LÄS MER

5. 4. PERFORMANCE OF THE PHOTODETECTOR FOR THE ACTIVE SHIELD OF THE COSI SPACE TELESCOPE

   Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Daniel Álvarez Franco; [2022]
   Nyckelord :Geant4; scintillation; BGO; CsI; simulation; COSI; telescope; photoelectric effect;

   Sammanfattning : The COmpton Spectrometer and Imager (COSI) is a space telescope that aims to study the soft gamma regime (0.2-5 MeV), capable of performing spectroscopy, imaging and polarimetry of cosmic gamma sources. LÄS MER

7. 5. Nuclear Structure near the Proton Drip-line: A Search for Excited States in 62Ge

   Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Dalia Farghaly; [2022]
   Nyckelord :nuclear physics; nuclear structure; proton drip-line; excited states; germanium; fusion-evaporation reaction; experimental nuclear physics; gamma sphere; gamma spectroscopy; HPGe detectors; data analysis; Physics and Astronomy;

   Sammanfattning : An experiment to study mirror symmetry in the mass A = 60 region was performed at the Argonne National Laboratory (ANL) in 2020. The fusion-evaporation reaction 40Ca + 24Mg → 64Ge* at a beam energy of 106 MeV was used to populate excited states in 62Ge. LÄS MER
