  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. 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.

  3. 3. 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.

  4. 4. Resolving temporal links between the Högberget granite and the Wigström tungsten skarn deposit in Bergslagen (Sweden) using trace elements and U-Pb LA-ICPMS on complex zircons

    University essay from Lunds universitet/Geologiska institutionen

    Author : Anders Plan; [2020]
    Keywords : Bergslagen; Wigström; Högberget; geochronology; geochemistry; U-Pb; REE; trace element; zircon; hydrothermal zircon; LA-ICPMS; SEM; skarn; tungsten; wolfram; scheelite; deposit; ore; critical raw material; Earth and Environmental Sciences;

    Abstract : Combined U-Pb and REE trace element LA-ICPMS analyses were performed on zircons, from the scheelite-bearing Wigström skarn, associated micro-granitic dykes and the highly evolved parental Högberget (sensu stricto) granite. Combined systematic of zircon typology and microtextures, trace elements and isotopic chemistry suggest the presence of several diverse zircon types, spanning from early- to late- magmatic stage into a hydrothermal stage.

  5. 5. Vendor-Independent Software-Defined Networking : Beyond The Hype

    University essay from Linköpings universitet/Databas och informationsteknik

    Author : Santiago Pagola Moledo; [2019]
    Keywords : SDN; network virtualization; cloud datacenter; Tungsten Fabric; Openstack; open-source; networks;

    Abstract : Software-Defined Networking (SDN) is an emerging trend in networking that offers a number of advantages such as smoother network management over traditional networks. By decoupling the control and data planes from network elements, a huge amount of new opportunities arise, especially in network virtualization. READ MORE
