  1. 1. Calculation of alpha knock-on neutron spectra from the 2021 JET DT campaign

    L3-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Arna Ormsdóttir; [2023]
    Nyckelord :Thermonuclear fusion; DT plasma; neutron spectra; supra-thermal ions;

    Sammanfattning : A python code was developed to compute the alpha knock-on (AKN) neutron spectrum using two already available computational tools. The code was used to calculate the AKN for a given discharge from the DTE2 JET campaign. Results showed that the beam-target contribution dominated the neutron spectra and obscured the AKN tail.

  3. 2. Effect of a new pedestal width constraint on the pedestal predictions with Europed in JET fusion plasmas

    Master-uppsats, KTH/Energiteknik

    Författare :Eleonora Iurlaro; [2022]
    Nyckelord :;

    Sammanfattning : As the whole world is facing and will face further challenges in the future in meeting the energy demand, thermonuclear fusion could be part of a future sustainable energy scenario. However, there are still many problems related to fusion that need to be addressed before implementing fusion energy in fusion power plants. LÄS MER

  4. 3. Design of Instrumentation & Control and Optical Table Instruments for the Divertor Flow Monitor Diagnostic at ITER

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

    Författare :Niklas Hermansson; [2022]
    Nyckelord :Coherence imaging; fusion; optics; plasma diagnostic; polarization; spectroscopy; Zeeman-Doppler imaging;

    Sammanfattning : This master's thesis describes the process of the design and instrument selection for a future optical table, part of a plasma flow monitor diagnostic system at the international thermonuclear experimental reactor, ITER. The diagnostic system is designed to detect the presence of edge localized mode, low to high confinement mode transition of plasma, and plasma flow velocity in the divertor region of the reactor.

  5. 4. Type-1 Active Falactic Nuclei and their Supernovae

    Magister-uppsats, Uppsala universitet/Teoretisk astrofysik

    Författare :Inigo Imaz Chacon; [2019]
    Nyckelord :SN; AGN; supernova; counts; star formation; astronomy; type-1 AGN; obscured; thermonuclear; core-collapsed;

    Sammanfattning : Supernovae (SNe) and more specifically Core-Collapsed SNe (CC SNe) are signatures of on-going star formation (SF), and higher star formation rates. In this project, we perform a study of all SNe ever discovered inside a specific type of galaxy: a type-1 Active Galactic Nucleus (AGN1). LÄS MER

  7. 5. Heating a Plasma to 100 Million Kelvin

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Gunnar Fröberg; Thomas Nygren; [2014]
    Nyckelord :;

    Sammanfattning : In this work techniques for heating the fusion reactor ITER to thermonuclear temperatures, over 100 million kelvin, is investigated. The temperature is numerically computed for different heating configurations. The heat leakage is modeled to occur only via diffusion. The diffusion is assumed to be a combination of Bohm and gyro-Bohm diffusion. LÄS MER
