  1. 1. Effect of the ICRH Antenna Position on the Coupled Power in ITER and JET

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

    Author : Olle Sundberg; Vincent Forsberg; [2023]
    Keywords : ;

    Abstract : Fusion energy has fascinated scientists for decades. One reason we do not see thispromising energy source powering today's society is the fact that the process requires extremeplasma temperatures. READ MORE

  3. 2. One-Dimensional Velocity Distributions of Fast Ions under RF Heating Including Doppler Shift in Tokamaks

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

    Author : Lukas Bähner; [2022]
    Keywords : plasma; fusion; ICRH; Ion Cyclotron Resonance Heating; RF; radio frequency; Fokker-Planck equation; Fokker-Planck solver; quasilinear operator; Coulomb collision; Doppler shift; velocity distribution; local temperature; plasma; fusion; ICRH; joncyklotronuppvärmning; RF; radiofrekvens; Fokker-Planck-ekvationen; Fokker-Planck-lösare; kvasilinjär operator; Coulombkollisioner; Dopplerskift; hastighetsfördelning; lokal temperatur;

    Abstract : The goal of nuclear fusion research is to create a clean and virtually limitless energy source. In order to that, a plasma must be heated to hundreds of millions degrees Celsius. A commonly used heating mechanism is ion cyclotron resonance heating, where antennas emit radio waves into the plasma. READ MORE

  4. 3. Comparison of RF Heating in ASDEX Upgrade and ITER

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

    Author : Axel Blennå; Mark Kalldas; [2022]
    Keywords : Fusion; ASDEX Upgrade; ITER; FEMIC; ICRH; eigenmode; beam; wave absorption;

    Abstract : The increased effects of global warming have been a driving force to further research and develop sustainable energy sources, such as fusion. In this study, two different fusion devices are compared in terms of ion cyclotron resonance heating (ICRH)of plasma. The two devices are the tokamaks ASDEX Upgrade and not yet built ITER. READ MORE

  5. 4. 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

  6. 5. Implementation of Collisions in FEMIC for Modelling of the RF Heating with a Lower Hybrid Resonance

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

    Author : Léo Belleil; [2020]
    Keywords : ;

    Abstract : Fusion energy is a potential sustainable solution to provide clean energy for the human society. The fusion reaction requires that the ionised fuel (plasma) is heated to extreme temperatures. Magnetic confinement is used to keep the plasma away from the wall and the components mounted on it.
