  1. 1. Simulating metal ct artefacts for ground truth generation in deep learning.

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Arthur Barakat; [2023]
    Keywords : Technology and Engineering;

    Abstract : CT scanning stands as one of the most employed imaging techniques used in clinical field. In the presence of metal implants in the field of view (FOV), distortions and noise appear on the 3D image leading to inaccurate bone segmentation, often required for surgery planning or implant design.

  3. 2. Simulation of Quantum Cascade Lasers

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Zakaria Mohamed; [2023]
    Keywords : Quantum Cascade Lasers; Simulations; Numerical Methods; Computational Models; Heterostructures; Physics and Astronomy;

    Abstract : This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. READ MORE

  4. 3. Comparison of different approaches for modelling the beam-target reactivity in fusion plasmas

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Marcus Petersson; [2022]
    Keywords : JET; Fusion; Fusion Diagnostics; Computational Physics; Modelling; NBI; Beam-Target Reactivity;

    Abstract : Fusion research has been an ongoing research endeavour for many decades and it has the potential of providing an important part in the future of energy production. An important part of this process is to understand and control the various heating systems of the reactor where one of the most important systems being the Neutral Beam Injector (NBI) which injects particles at high velocities into the plasma.

  5. 4. 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. 5. Frequency Map Analysis of the MAX IV Storage Rings

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

    Author : Johan Lundquist; [2019]
    Keywords : Accelerator; MAX IV; Tune; Diagnostics; Turn by turn; Frequency map; Chromaticity; Beta function; BPM; Synchrotron; Physics and Astronomy;

    Abstract : As a beam of particles moves through a storage ring each particle will perform transverse oscillations as a result of the focusing magnetic fields it encounters. The amount of transverse oscillations performed in a single revolution of the ring is known as the particle's betatron tune. READ MORE
