  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

    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. Including Finite Larmor Radius Effects on RF Heating of Fusion Plasmas using Weak-Form Contributions in COMSOL

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

    Author : Jonas Christ; [2022]
    Keywords : plasma; fusion; RF; radio frequency; IBW; FW; ion Bernstein wave; fast wave; simulation; FEM; finite element method; Taylor; Taylor expansion; COMSOL; MATLAB; FLR; finite larmor radius; magnetized plasma; hot plasma; thermal plasma; plasma; fusion; radiofrekvens; simulation; FEM; finita elementmethod; Taylor; Taylorutveckling; COMSOL; MATLAB; FLR; ändliga Larmorradie-effekter;

    Abstract : In a fusion plasma, the ions have to be heated to reach fusion relevant temperatures. One possibility is to launch an electromagnetic wave in the radio frequency band into the plasma. This wave can resonate with the ions at their cyclotron frequency and hence, the method is called ion cyclotron resonance heating. READ MORE

  6. 5. Motion Planning for Aggressive Flights of an Unmanned Aerial Vehicle

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

    Author : Cornelia Smith; Filippa Femic; [2022]
    Keywords : UAV; autonomous vehicle; motion planning; polytope intersection; trajectory generation; obstacle handling; collision avoidance; feasibility constraints; differential flatness;

    Abstract : Unmanned aerial vehicles are becoming more popular in today’s society, which results in the rise of laws intended to maintain safety. To abide by these, while allowing the technology to expand, functioning path-planning algorithms are required.This also includes having methods for detecting and managing obstacles. READ MORE
