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

    University essay from Uppsala universitet/Tillämpad kärnfysik

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

    Abstract : 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

    University essay from KTH/Energiteknik

    Author : Eleonora Iurlaro; [2022]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Tillämpad kärnfysik

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

    Abstract : 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. Heating a Plasma to 100 Million Kelvin

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gunnar Fröberg; Thomas Nygren; [2014]
    Keywords : ;

    Abstract : 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. READ MORE

  6. 5. Multi-Sensor Data Fusion for a Long-Reach Robot

    University essay from KTH/Reglerteknik

    Author : Maria Makarov; [2010]
    Keywords : ;

    Abstract : The purpose of this Master's thesis project is the study and the improvement of the positioning of a long-reach robot. The AIA robot is a 10 meter long multi-link manipulator developed at CEALIST (France), and designed for close inspection and maintenance of the inner walls of a thermonuclear reactor (tokamak) under vacuum and high temperature conditions.
