  1. 1. The Magnetocaloric Effect in Antiferromagnetic and Noncollinear Magnets

    University essay from Uppsala universitet/Materialteori

    Author : Siri Alva Berge; [2023]
    Keywords : magnetocaloric effect; atomistic spin dynamics; monte carlo; antiferromagnet; neodymium; noncollinear magnetism;

    Abstract : The magnetocaloric effect (MCE) is the temperature change in a magnetic material due to a change in an applied magnetic field. How the MCE behaves in different magnetic materials and at different phase transitions is fundamental to understand. READ MORE

  3. 2. Improving the safe mode robustness of an Earth observation satellite

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Guillaume Trimoreau; [2022]
    Keywords : avoidance; dazzling; magnetic control; Monte Carlo; safe mode; simulation; tuning; solundvikelsemanöver; solbländning; magnetisk kontroll; Monte Carlo-metoden; säkra läget; simulation; inställning;

    Abstract : Airbus Defence and Space is developing an Earth observation platform. The payload of that platform is an optical instrument, which has to be protected from Sun dazzling in order to preserve its integrity. READ MORE

  4. 3. Monte-Carlo computations of dose distributions for magnetic resonance guided radiotherapy

    University essay from Uppsala universitet/FREIA

    Author : Claes Fälth; [2021]
    Keywords : Radiotherapy; MRgRT;

    Abstract : The goal with radiotherapy is to damage tumour cells with ionizing radiation while minimizing radiation to healthy tissue. In recent years magnetic resonance guided radiotherapy has become increasingly popular. With this technique a magnetic resonance image of the patient anatomy is obtained in connection with the treatment session. READ MORE

  5. 4. Magnetic nozzle plume plasma simulation through a Particle-In-Cell approach in a 3-D domain for a Helicon Plasma Thruster. : A collaboration with REGULUS project T4i Technology for Propulsion and Innovation s.p.a.

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

    Author : Cesare Vesco; [2021]
    Keywords : Particle-In-Cell PIC ; Monte Carlo; Helicon Plasma Thruster; SPIS; Magnetic Nozzle; collisions; cross sections.; Particle-In-Cell PIC ; Monte Carlo; Helicon Plasma Thruster; SPIS; Magnetiska Dysan; kollisions; cross sections.;

    Abstract : Recent advances in plasma-based propulsion systems have led to the development of electromagnetic Radio-Frequency (RF) plasma generation and acceleration systems, called Helicon Plasma Thrusters (HPT). One of the pioneer companies developing this new type of space propulsion is T4i Technology for Propulsion and Innovation s.p.a. READ MORE

  6. 5. Quantum statistics and the magnetocaloric effect

    University essay from Uppsala universitet/Materialteori

    Author : Anna Sandberg; [2020]
    Keywords : quantum statistics; magnetocaloric effect; magnetocaloric; magnetic cooling; simulation;

    Abstract : Caloric materials show prospect in replacing the function of vaporcompression systems in todays cooling devices, resulting in more energy efficient cooling and eliminating the need for refrigerents which contribute to climate change. This project has focused on magnetocaloric materials, which experience changes in temperature when exposed to magnetic fields. READ MORE
