  1. 1. Development of a guide system for free neutron oscillation searches at the European Spallation Source

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/European Spallation Source ESS AB

    Författare :Linnéa Björk; [2023]
    Nyckelord :ESS; neutrons; dark matter; antimatter; neutron guides; Physics and Astronomy;

    Sammanfattning : In this project, a neutron delivery system for the study of free neutron oscillations at the HIBEAM beamline at the European Spallation Source (ESS) has been developed. The HIBEAM experiment is part of a two-stage program at ESS which will address open questions in physics; specifically the nature of dark matter and the observed asymmetry between matter and antimatter in the Universe.

  2. 2. Machine Learning Applications for the HIBEAM-NNBAR experiment at the European Spallation Source

    Kandidat-uppsats, Stockholms universitet/Fysikum

    Författare :William Lejon; [2022]
    Nyckelord :Machine learning; NNBAR;

    Sammanfattning : NNBAR is a proposed experiment for the European Spallation Source. Thegoal of the experiment is to observe the transformation n −  ̄n. Currently a cutbased analysis is used to select signal events and discriminate against cosmic raybackground. To further increase the signal efficiency machine learning was used. LÄS MER

  3. 3. 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
