  1. 1. Modeling of RF Heating in the JET Tokamak

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Emil Söderman; Wilhelm Holmberg; [2021]
    Keywords : fusion; tokamak; ICRH; RF heating; JET;

    Abstract : Fusion reactors need methods to couple externalpower to confined plasmas. Ion cyclotron resonance heating(ICRH) is a method to radiate electromagnetic waves to couplepower to the kinetic motion of gyrating ions in a plasma. In thisreport we study ICRH with regard to the dispersive effects ofthe confined plasma in the JET tokamak. READ MORE

  3. 2. Optimization of Heat Exhaust in the Edge of Tokamaks via Controlled Magnetic Stochastization

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Amit Kharwandikar; [2020]
    Keywords : Resonant Magnetic Perturbations; Tokamak; Divertor; Steady-state heat deposition; Power exhaust; Perturbation optimization; Resonant magnetiska störningar; Tokamak; avledare; statisk värmeavledning; värmeavledningen; störningsoptimering;

    Abstract : The protection of plasma facing components from heat and particle overloads is paramount to ensure the operability and desired lifetime of magnetic fusion devices. The possibility of using external 3D magnetic perturbations to improve the steady-state heat exhaust in diverted tokamaks has been studied in this thesis. READ MORE

  4. 3. Modeling of the pedestal performance in the DTT tokamak

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Hampus Nyström; [2020]
    Keywords : Fusion; pedestal; DTT;

    Abstract : This master thesis concerns the modeling of the pedestal in the fusion plasma device DTT and its dependence on several plasma parameters. The modeling was performed using the Europed code which is based on the EPED model. Several parameters were found to have a significant impact on the pedestal predictions. READ MORE

  5. 4. Upgrade of the Analytical System for Studies of Plasma-Facing Components from a Tokamak

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alexander Djadkin; Emrah Tortumlu; [2020]
    Keywords : fusion; retention; molybdenum; plasma-facing-component; automation; deuterium implantation;

    Abstract : Fusion energy is a potential candidate for sustain-able steady-state energy supply. However, a fully functional fusion reactor is not yet available and several remaining challenges need to be addressed before fusion becomes a reliable source. READ MORE

  6. 5. Characterization of γ-rays at MAST

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Erik Blom; [2019]
    Keywords : fusion; MAST; MAST upgrade; neutron collimated flux monitor; neutron camera; gamma-ray;

    Abstract : The γ-ray characterizing possibility of the neutron collimated flux monitor (in short, Neutron Camera) at the Mega Ampere Spherical Tokamak (MAST) is explored. Typically used to monitor neutron emission, the Neutron Camera has excellent neutron/γ-ray discrimination properties and thus presents the opportunity to measure spatially and temporally resolved γ-ray emission - a possibility of an additional fusion diagnostics method with already existing equipment.
