  1. 1. Background Studies of the High-Intensity Baryon Extraction and Measurement (HIBEAM) Experiment at the European Spallation Source

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Blahoslav Rataj; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The High-Intensity Baryon Extraction and Measurement experiment (HIBEAM) is proposed as one of the experimental stations at the European Spallation Source (ESS). This experiment will mainly focus on the neutron into sterile neutron oscillations which violate the baryon number (B) by one unit. LÄS MER

  3. 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

  4. 3. Vanadium-based neutron-beam monitor

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

    Författare :Vendula Maulerova; [2019]
    Nyckelord :thermal neutrons Helmholtz-Zentrum Berlin Neutron-beam monitor Vanadium; Physics and Astronomy;

    Sammanfattning : A prototype invasive (quasi-parasitic) thermal-neutron beam monitor based on isotropic neutron scattering from a thin natural Vanadium foil and standard $^3$He proportional counters has been conceptualized, designed, simulated, calibrated, and commissioned. As the beam monitor is invasive, very low neutron-beam attenuation is a necessary characteristic. LÄS MER

  5. 4. Simulating Long Neutron Beamlines Using Duct Source Variance Reduction in Geant4

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

    Författare :Isak Svensson; [2018]
    Nyckelord :Neutron beamlines; neutron shielding; high energy neutrons; variance reduction; Geant4; Monte Carlo simulation; Physics and Astronomy;

    Sammanfattning : The European Spallation Source, ESS, is set to become the world's brightest spallation neutron source. Spallation neutron sources present unique challenges with regards to radiation shielding due to the creation of a significant number of high energy neutrons during nuclear reactions in the spallation target.

  7. 5. Neutron wavelength estimation on crystal monochromator beamlines

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Anton Eklind Schultz; [2014]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The world wide shortage of helium-3 is forcing the development of new detectors for neutron spectroscopy. A candidate for new detector design that consists of multiple detection volumes in depth, in contrast to the traditional single volume helium-3 detector, is being developed at ESS in Lund. LÄS MER
