1. 1. Trigger-Level Multiple Electron Event Classification with LDMX using Artificial Neural Networks

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Jacob Lindahl; [2023]
   Keywords : LDMX; ANN; CNN; GNN; RNN; DM; Physics and Astronomy;

   Abstract : Artificial neural networks is a powerful tool for classifying and identifying patterns in large amounts of data. One of the possible tasks of these networks is classification of data into categories. READ MORE

3. 2. Optical characterisation of AAO/CsPbBr3 perovskite nanocomposites

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

   Author : Klára Nováková; [2021]
   Keywords : perovskite; scintillator; optoelectronics; semiconductor; X-ray detection; Physics and Astronomy;

   Abstract : Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices.

4. 3. Test setup for LDMX HCal readout

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Joshua Greaves; [2020]
   Keywords : Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

   Abstract : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

5. 4. Characterisation of a New Type of Solid Organic Scintillator for neutron-gamma Discrimination using Pulse-Shape DiscriminationTechniques

   University essay from Uppsala universitet/Kärnfysik

   Author : Qadir Nishada; [2014]
   Keywords : EJ-299-33; PSD; Pulse-shape discrimination; plastic scintillator; neutron-gamma discrimination; scintillator decay times;

   Abstract : In this report the neutron-gamma discrimination capabilities of the new type of solid organic scintillator, EJ-299-33, was investigated using several pulse-shape discrimination (PSD) techniques. Among others, the analog zero-crossing method andthe digital charge-comparison and integrated-rise-time method were tested. READ MORE
