1. 1. Analysis of Atmospheric Muon Bundles with IceCube

   University essay from Uppsala universitet/Högenergifysik

   Author : Anna Selina Neyer; [2024]
   Keywords : ;

   Abstract : This work is a preliminary study of the background of a search for dark, long-lived particles in the IceCube detector. The high flux of atmospheric muons in IceCube is considered background to the detector's primary science goal, which is to detect astrophysical neutrinos through the emission of Cherenkov radiation.

3. 2. A Machine Learning Approach on Analysis of Emission Spectra for Application in XFEL Experiments

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Harald Agelii; [2023]
   Keywords : Structural biology; Machine learning; Neural networks; emission spectrum; XFEL; X-ray free electron laser; SFX; Serial femtosecond X-ray crystallography; Proteins; Diagnostics;

   Abstract : In this thesis we investigate two potential applications of machine learning in the context of X-ray imaging and spectroscopy of biological samples, particularly such using X-ray free electron lasers (XFEL). We first investigate the possibility of using an emission spectrum, recorded from a sample after being probed by an incident X-ray, as a diagnostic tool. READ MORE

4. 3. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

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

   Author : Isa Clementsson; [2023]
   Keywords : Physics and Astronomy;

   Abstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

5. 4. Effect of infill density on mechanical and fire properties of polylactic acid composites produced by FDM 3D-printing technology

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : David Aronsson Edström; Oskar Lundberg; [2022]
   Keywords : 3D-printing; FDM; PLA; fire; fire engineering; cone calorimeter; tensile test; UL-94;

   Abstract : 3D-printing is a new and upcoming manufacturing technique that can significantly reduce time and material losses in production. Fused deposition modeling (FDM) is one of the most commonly used 3D-printing methods for processing conventional thermoplastic polymers. READ MORE

6. 5. X-Ray Fluorescence of Metal Halide Perovskites

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

   Author : Samuel Narciso Silva; [2022]
   Keywords : Perovskite; X-ray; Fluorescence; Python; PyMCA; Synchrotron radiation; Physics and Astronomy;

   Abstract : This thesis has the aim to provide a framework for analyzing X-ray fluorescence (XRF) data obtained from German Electron-Synchrotron Group (DESY). The theoretical analysis shows that XRF competes with Auger emission, and works mainly for elements with high atomic number. Here, incident X-rays of 13. READ MORE
