  1. 1. Fast Simulations of Radio Neutrino Detectors : Using Generative Adversarial Networks and Artificial Neural Networks

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Anton Holmberg; [2022]
    Nyckelord :Askaryan emission; Radio detection of neutrinos; in-ice propagation; neutrino; Generative adversarial networks; GAN; WGAN; Neural networks; NN; surrogate model; IceCube; deep learning; generative model;

    Sammanfattning : Neutrino astronomy is expanding into the ultra-high energy (>1017eV) frontier with the use of in-ice detection of Askaryan radio emission from neutrino-induced particle showers. There are already pilot arrays for validating the technology and the next few years will see the planning and construction of IceCube-Gen2, an upgrade to the current neutrino telescope IceCube.

  3. 2. Birefringence: Effects and Implications on In-Ice Radio Detection of High-Energy Neutrinos

    Master-uppsats, Uppsala universitet/Högenergifysik

    Författare :Nils Heyer; [2022]
    Nyckelord :Birefringence; Cosmic Neutrinos; In-ice radio propagation;

    Sammanfattning : The detection of high-energy neutrinos in the EeV range requires new detection techniques to cope with the small expected flux. The radio detection method, utilizing Askaryan emission, can be used to detect these neutrinos in polar ice. LÄS MER

  4. 3. Simulation of birefringence effects for high-energy neutrino detectors

    L3-uppsats, Uppsala universitet/Högenergifysik

    Författare :Nils Heyer; [2021]
    Nyckelord :astroparticle physics; radio detection; high-energy neutrinos; birefringence;

    Sammanfattning : The detection of high-energy neutrinos in the E > O(PeV) range requires newdetection techniques in order to cope with the decreasing flux. The radio detectionmethod uses Askaryan emission to detect these neutrinos. LÄS MER

  5. 4. Measurement of the snow accumulation in Antarctica with a neutrino radio detector and extension to the measurement of the index-of-refraction profile

    L3-uppsats, Uppsala universitet/Högenergifysik

    Författare :Jakob Beise; [2021]
    Nyckelord :Askaryan; UHE neutrinos; in-ice radio detection; in-situ detector calibration; deep learning; radio neutrino detector; ARIANNA;

    Sammanfattning : High-energy neutrino physics offers a unique way to investigate the most violent phenomena in our universe. The detection of energies above E > 1017 eV is most efficient using the Askaryan effect, where a neutrino-induced particle shower produces coherent radio emission that is detectable with radio antennas.

  7. 5. In-situ calibration device of firn properties for Askaryan neutrino detectors

    L2-uppsats, Uppsala universitet/Högenergifysik

    Författare :Jakob Beise; [2021]
    Nyckelord :Askaryan; UHE neutrinos; in-ice radio detection; in-situ detector calibration; deep learning; radio neutrino detector; ARIANNA;

    Sammanfattning : Simulations have demonstrated that high-energy neutrinos (E > 1017 eV) are detected cost-efficiently via the Askaryan effect in ice, where a particle cascade induced by the neutrino interaction produces coherent radio emission that can be picked up by antennas installed below the surface. A good knowledge of the near surface ice (aka firn) properties is required to reconstruct the neutrino properties. LÄS MER
