  1. 1. Towards a European Space Radiation Risk Model: : Knowledge gaps and risk model concept

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Sandra Nilsson; [2019]
    Nyckelord :Radiobiology; Space Radiation;

    Sammanfattning : Space travelling within the solar system is expected to expand within the upcoming years, with the Moon and Mars as main targets. These longer space flights results in longer time periods within a complex radiation environment for the astronauts. LÄS MER

  2. 2. Development of a DC Beam Model for the First Prototype of the ESS Virtual Machine

    Magister-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Benjamin Bolling; [2019]
    Nyckelord :Particle; Accelerator; Beam; Physics; Science; Virtual Machine; Virtual; Machine; Physics and Astronomy;

    Sammanfattning : The European Spallation Source is currently under construction in Lund, Sweden. Consisting of a linear accelerator delivering an unprecedented 5 MW proton beam to the spallation source, i.e. LÄS MER

  3. 3. Fitting the three loop pion mass and decay constant to lattice data

    Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik; Lunds universitet/Teoretisk partikelfysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Författare :Alexandra Wernersson; [2019]
    Nyckelord :Chiral Perturbation Theory; Lattice QCD; pion mass; decay constant; three loop fit.; Physics and Astronomy;

    Sammanfattning : We perform a fit to three loop order (NNNLO) in Chiral perturbation theory of the pion mass and decay constant. In particular we investigate if the NNNLO fit is an improvement of the fit to two loop order (NNLO) to lattice QCD data, which was done in a lattice gauge group collaboration. LÄS MER

  4. 4. A Fabry–Pérot Cavity for Rare-Earth-Ion-Doped Nanocrystals

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

    Författare :Andre Nüsslein; [2019]
    Nyckelord :Quantum Computer; Rear Earth Ions; Cavity; Laser; Cavity Quantum Electrodynamics; QED; Solidworks; Physics and Astronomy;

    Sammanfattning : This thesis work contributes to the effort of detecting single rare earth ions doped into crystals, an operation crucial for the development of rare earth quantum computer hardware. Doping crystals with rare earth elements, their trivalent ions substitute some of the crystal’s original bonds. LÄS MER

  5. 5. Simulation of solidification and cooling of a casting product using COMSOL Multiphysics

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Tom Allen; [2019]
    Nyckelord :Heat transfer; casting; phase change; COMSOL Multiphysics; Technology and Engineering;

    Sammanfattning : In this project, the cooling and solidification processes for a Valmet Foundry product have been simulated in order to shorten the cooling time. The study has also been done in cooperation with RISE Swecast in Jönköping, as a part of finding ways to make casting procedures more energy efficient. LÄS MER
