  1. 1. Energy reconstruction with artificial neural networks on LDMX simulations

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

    Author : Daniel Magdalinski; [2020]
    Keywords : Dark matter; LDMX; electromagnetic calorimeter; neural networks; convolutional neural networks; Physics and Astronomy;

    Abstract : It is clear from evidence such as rotational curves and cosmic microwave background measurements that dark matter exists. The light dark matter experiment (LDMX) will search for dark matter in the sub-GeV range. It will do this using missing-momentum measurements of electrons interacting with a Tungsten target.

  2. 2. Nanoscale detection of insulin granule sub-structures using dSTORM imaging

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

    Author : Yu Hong; [2020]
    Keywords : islet β-cells; dSTORM imaging; Alexa Fluor 647; Physics and Astronomy;

    Abstract : Diabetes mellitus is a global disease, mainly caused by insufficient insulin secre- tion from pancreatic islet β-cells. Insulin is stored in the granules of islet β-cells and released in response to extracellular stimuli e.g. glucose. READ MORE

  3. 3. Test setup for LDMX HCal readout

    University essay from Lunds universitet/Partikelfysik; 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.

  4. 4. Signal and Background Studies at 8 GeV for the Light Dark Matter eXperiment

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

    Author : Péter György; [2020]
    Keywords : LDMX; Dark Matter; Light Dark Matter; 8 GeV; Physics and Astronomy;

    Abstract : Light dark matter is a hypothesized form of dark matter in the 1 MeV to 1 GeV mass range. The Light Dark Matter eXperiment (LDMX) is an upcoming experiment to test the existence of light dark matter, by colliding an electron beam with a tungsten target and assembling a set of events that potentially indicate the existence of light dark matter.

  5. 5. Implementation of Scheimpflug Lidar for Entomological Monitoring of Bark Beetles

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

    Author : Jonathan Peterson; [2020]
    Keywords : Scheimpflug Lidar; Lidar; Bark beetles; Forestry; Entomological monitoring; Physics and Astronomy;

    Abstract : Bark beetles are responsible for great damages to Swedish forestry every year. This project focuses on a method of entomological lidar called Scheimpflug lidar to detect and monitor bark beetles. Scheimpflug lidar uses old techniques from photography to achieve a deep field of focus to resolve objects over long distances. READ MORE
