1. 6. Investigation of the Plasma delay time in PIPS detectors using the LOHENGRIN spectrometer

   L3-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Elizaveta Yakovleva; Ivar Wikander; [2022]
   Nyckelord :;

   Sammanfattning : This project has examined the effects of plasma delay time (PDT) and pulse height defect (PHD) for protons, tritons and alpha particles. The goal was to determine PDT and PHD for alpha particles relative to protons, by using data from a subset of measurements taken with a silicon detector of type PIPS at the LOHENGRIN spectrometer.

3. 7. On the Energy Dependence of Parameters in PYTHIA8 Heavy-ion Collision Simulations

   Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Felipe Abedrapo; [2022]
   Nyckelord :Heavy-ion Collisions; PYTHIA; Angantyr; Physics and Astronomy;

   Sammanfattning : Particle collisions are an essential component to the research methodology of particle physics. These investigations are not only conducted in experimental laboratories but also through programs such as PYTHIA that simulate a collision or ``event" and then compare its results to known experimental data.

4. 8. 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

5. 9. An Inexpensive Alpha Spectrometer Based on a p-i-n Photodiode : Making Advanced Particle Detectors From Common Commercial Components

   Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

   Författare :Elias Arnqvist; [2022]
   Nyckelord :Alpha spectroscopy; alpha particle; particle detector; radiation detector; p-i-n diode; PIN diode; photodiode;

   Sammanfattning : The purpose of this project was to design, construct, and evaluate an alpha spectrometer based on an inexpensive p-i-n photodiode as a radiation detector. The BPX-61 p-i-n photodiode was selected and calculated to have a 93 µm wide sensitive volume at 25 V reverse bias. LÄS MER

7. 10. Dead layer determination for the new implantation detector of the LUNDIUM decay station

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

   Författare :Eleftheria Kosta; [2022]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : The Nuclear Structure Group in Lund, focuses on nuclear spectroscopy of decays of rare isotopes. A new decay station, called LUNDIUM, is currently being built, which will involve silicon and germanium detectors for the study of these nuclei. This thesis focuses on the characterization of one of the new silicon detectors, the implantation one. LÄS MER
