1. 16. Constraining Physics Beyond the Standard Model with Emerging Jets using the ATLAS Experiment

   Kandidat-uppsats, KTH/Fysik

   Författare :Simon Thor; [2022]
   Nyckelord :ATLAS; CERN; particle physics; simulation; Python; C ; standard model; emerging jets; long-lived particles;

   Sammanfattning : Dark matter, the unknown matter that constitutes 85% of all matter in the universe, is one of the greatest mysteries in fundamental physics. One theory that might explain dark matter predicts that there are long-lived particles known as dark pions. LÄS MER

3. 17. Modeling of Low-Energy Neutron Scattering in Liquid Hydrogen Using NCrystal

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Kärnfysik

   Författare :Tim Günter; [2022]
   Nyckelord :ESS; European Spallation Source; neutron; scattering; moderator; liquid hydrogen; modeling; ncrystal; njoy; Physics and Astronomy;

   Sammanfattning : The European Spallation Source ESS, under construction in Lund, Sweden, aims to produce high-brightness and intensity neutrons for a multitude of experiments upon completion. An efficient production of neutrons requires elaborate understanding of the moderation process which slows the neutrons from relativistic speed to a kinetic energy of meV. LÄS MER

4. 18. Tuning of the ESS Drift Tube Linac using Machine Learning

   Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

   Författare :Johan Lundquist; [2022]
   Nyckelord :Accelerator; drift tube linac; machine learning; neural network; ESS; linac; tuning; proton; longitudinal dynamics; beam physics; Physics and Astronomy;

   Sammanfattning : The European Spallation Source, currently under construction in Lund, Sweden, will be the world's brightest neutron source. It is driven by a linear accelerator designed to accelerate a beam of protons with 62.5 mA, 2.86 ms long pulses, working at 14 Hz. LÄS MER

5. 19. Multi-spectral X-ray imaging with a laser-plasma accelerator

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

   Författare :Andrea Angella; [2022]
   Nyckelord :Multi-spectral imaging; single-photon counting; X-ray absorption spectroscopy; XAS; LWFA; laser-wakefield acceleration; K-edge; imaging; metal-detection algorithm; Physics and Astronomy;

   Sammanfattning : This master thesis focuses on the creation of an algorithm to perform multispectral imaging of a metallic target using X-rays. The generation of an ultrashort high-power low-divergent X-ray beam is performed by means of a Ti:Sapphire laser driven wake-field plasma accelerator. LÄS MER

7. 20. 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
