  1. 1. 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

    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

  3. 3. 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

  4. 4. MAC-E-Filter characterization for PTOLEMY : a relic neutrino direct detection experiment

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Carl-Fabian Strid; [2019]
    Keywords : particle physics; astroparticle physics; astrophysics; PTOLEMY; relic neutrinos; monte carlo simulation; mac-e-filter; sterile neutrinos; physics beyond the standard model;

    Abstract : The cosmic neutrino background (CNB) can be composed of both active and hypothetical sterileneutrinos. At approximately one second after big bang, neutrinos decoupled from radiationand matter at a temperature of approximately one MeV. READ MORE

  5. 5. Best practice of extracting magnetocaloric properties in magnetic simulations

    University essay from Uppsala universitet/Materialteori

    Author : Johan Bylin; [2019]
    Keywords : Magnetocaloric effect; Thermodynamics; Statistical mechanics; Monte Carlo simulations; Metropolis algorithm; Wang-Landau method; Isothermal change in entropy; Adiabatic change in temperature; Numerical methods; Effective spin models;

    Abstract : In this thesis, a numerical study of simulating and computing the magnetocaloric properties of magnetic materials is presented. The main objective was to deduce the optimal procedure to obtain the isothermal change in entropy of magnetic systems, by evaluating two different formulas of entropy extraction, one relying on the magnetization of the material and the other on the magnet's heat capacity.
