1. 16. 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. 17. 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. 18. Characterization of Double Sided Silicon Strip Detectors from LYCCA modules for FAIR

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

   Author : Dalia Farghaly; [2019]
   Keywords : Physics and Astronomy;

   Abstract : Begun in 2010, the Lund-York-Cologne-CAlorimeter, LYCCA, collaboration is targeted at discovering exotic nuclear reaction products whilst implementing the possibility of both position tracking and measuring residual energies of relativistic particles. Each LYCCA module is composed of a double sided silicon detector and 9 CsI(Tl) detectors. READ MORE

5. 19. Vanadium-based neutron-beam monitor

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

   Author : Vendula Maulerova; [2019]
   Keywords : thermal neutrons Helmholtz-Zentrum Berlin Neutron-beam monitor Vanadium; Physics and Astronomy;

   Abstract : A prototype invasive (quasi-parasitic) thermal-neutron beam monitor based on isotropic neutron scattering from a thin natural Vanadium foil and standard $^3$He proportional counters has been conceptualized, designed, simulated, calibrated, and commissioned. As the beam monitor is invasive, very low neutron-beam attenuation is a necessary characteristic. READ MORE

6. 20. Modelling and Simulations of a clinical PET-system using the GATE Monte Carlo software

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Philip Kalaitzidis; [2018]
   Keywords : Medicine and Health Sciences;

   Abstract : Introduction: The increased importance of PET imaging in the health care system has lead to a constant need for improvement and optimisation of scanner systems and their protocols. By utilising the features of the GATE Monte Carlo program one can gain a better understanding of the limitations and possibilities of the system. READ MORE
