  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. Ion Cyclotron Resonance Heating in WEST

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

    Author : Elvis Rodas; [2019]
    Keywords : tokamak; WEST; ICRH; FEMIC.;

    Abstract : In a fusion power plant the plasma must be confined to prevent instabilities and energy loss. The confinement machine studied is a tokamak. The focus of the project is to optimize ion resonance heating in WEST. READ MORE

  4. 3. Incoherent Scattering of Twisted Radar Beams from the Ionosphere

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Viktor Lannér; [2017]
    Keywords : ionosphere; plasma; twisted beams; orbital angular momentum; oam effects;

    Abstract : In the search for natural orbital angular momentum (OAM) effects, some of the first incoherent scatter experiments with twisted radar beams during aurora were conducted at Poker Flat Incoherent Scatter Radar (PFISR), Alaska, USA, in October 2012. Experimental data of scatter from beam configurations with opposite twists were investigated. READ MORE

  5. 4. Noise sources in the electric field antenna on the ESA JUICE satellite

    University essay from

    Author : Elias Odelstad; [2013]
    Keywords : JUICE; noise; quasi-thermal noise; QTN; Nyquist noise; shot noise; Langmuir probes; electric field probes;

    Abstract : The noise in the Langmuir Probe and Plasma Wave Instrument (LP-PWI) on board ESA:s future Jupiter satellite JUICE (Jupiter ICy Moons Explorer) was investigated. Thermal Johnson-Nyquist noise and shot noise, caused by fluctuations in the probe-plasma currents, were combined with the quasi-thermal noise (QTN) due to thermal fluctuations in the electric field in the plasma, using a small signal equivalent circuit model.
