  1. 16. 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. 17. The Stern-Gerlach Spectrometer for Charged Particles : A step towards an alternative method for measuring spin

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Samuel Eriksson; [2023]
    Keywords : Stern-Gerlach; Stern; Gerlach; spin; time-of-flight; time of flight; magnetic moment; spectrometer; Physics and Astronomy;

    Abstract : The purpose of this project is to investigate the performance of a spectrometer capable of measuring both momentum and spin of particles. More specifically, we investigated what parameters are required in order to separate particles with opposite spins at least 1 mm. READ MORE

  5. 19. Determination of Proton Beam Waist Positions Using Beam Position Monitors

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Synkrotronljusfysik

    Author : Gustav Gird Fahlström; [2022]
    Keywords : ESS; European Spallation Source; Proton beam; waist; BPM; Method; transverse; beam dynamics; beam physics; Lattice Error; Matrix formalism; Python; trajectory simulation; physics; Physics and Astronomy;

    Abstract : In this work, we examine a novel method for the determination of proton beam waist locations using beam position monitors. Based on the lattice of the final transport line section of the European Spallation Source linac, a simplified version of the beam line composed of quadrupole magnets and correctors is constructed in Python using a matrix formalism.

  6. 20. Real-Time Rotor Temperature Estimation Method for Interior Permanent Magnet Synchronous Machines : A method using a Lumped Parameter Thermal Network in combination with an estimation algorithm: implementation and comparison of a Dual Kalman Filter and a Dual Observer

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

    Author : Elvira Niemelä; [2022]
    Keywords : Permanent Magnet Synchronous Machine; Permanent Magnet Temperature Estimation; Lumped Parameter Thermal Network; Dual Kalman Filter; Dual Observer; Permanentmagnetiserad Synkronmaskin; Temperaturestimering för Permanentmagneter; Lumped Parameter Thermal Network; Dual Kalman Filter; Dual Observer;

    Abstract : Accurate knowledge of the temperature of a Permanent Magnet Synchronous Machine is of high importance, not only to ensure safe operation and improve control of the operating point, but also to avoid irreversible demagnetization of rare-earth permanent magnets. However, direct measurement using thermal sensors is not suitable for high volume and low-cost applications, due to costly sensor installation and maintenance, and therefore, the magnet temperature needs instead to be estimated.
