  1. 21. Synchrotrons as a Source for Soft X-Ray Lithography

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Thomas Joseph Grandsaert Jr; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : To move to lower modes in extreme ultra-violet lithography (EUVL) technology (and keep up with Moore’s law), new sources of soft X-ray radiation must be developed. It is clear from previous studies that Free Electron Lasers (FELs) can easily meet the in-band power requirements at these lower wavelength modes, however detailed studies for insertion devices (undulators) as a soft X-ray lithography (SXL) source are due for a re-evaluation.

  3. 22. Development of a CNC Milling System for Preparation of Micrometer-Sized Samples for X-ray Nanotomography

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Olivia Messler; [2021]
    Nyckelord :Nanotomography; Sample Preparation; CNC; Nanotomografi; Provpreparering; CNC;

    Sammanfattning : X-­ray nanotomography is an imaging technique used to study three­-dimensional structures at submicrometer length scale. The samples to be studied should be only 10s of micrometers in diameter, and ideally cylindrical. LÄS MER

  4. 23. Understanding Rt using two-particle correlations by simulating proton-proton collisions in a Monte-Carlo model

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Johan Leygonie; [2021]
    Nyckelord :QGP; Quark-Gluon-Plasma; Rt; Particle Physics; Proton-proton Collisions; Pythia; Monte-Carlo Model; Bachelor s Thesis; Heavy-ion Collisions; ALICE; CERN; Relative Transverse Activity; Jets; Two-Particles Correlations; Quantum Physics; Physics and Astronomy;

    Sammanfattning : The observable Rt is investigated in the Monte Carlo Model Pythia in order to better understand results from experimental data obtained in the ALICE detector at CERN. The purpose is to reproduce the experiment in a simulation and use the features proposed by Pythia to dig into the unexpected outcomes. LÄS MER

  5. 24. Synchrotron X-ray Tomography Study of Bone-implant Integration

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Ornella Lohéac; [2021]
    Nyckelord :Bone-implant; Digital volume correlation; Micro-computed tomography; PEEK; Synchrotron; Technology and Engineering;

    Sammanfattning : Implant loosening is a recurring problem in the field of orthopedics, typically resulting in a physical and financial burden for the patient. Proper integration of orthopedic implants within host bones is a fundamental requirement for the successful function and limited risk of failure of implants which, in-vivo, must support various loading conditions.

  7. 25. Evaluation of tomographic methods for limestone characterization : Using synchrotron-based X-ray tomography to determine porosity, internal structure and internal distributions in limestone

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Albert Askengren; [2021]
    Nyckelord :Limestone; X-ray tomography; Synchrotron; XRT; Synchrotron-based XRT;

    Sammanfattning : Limestone is a raw material in the cement and quicklime industry and knowledge about limestone characteristics can help improve and optimize production processes. In the end this can lead to a reduction in CO2 emissions from the industry. In this project X-ray tomography (XRT) was used to examine limestone samples. LÄS MER
