  1. 1. Computational investigation of the feasibility touse solid neon moderation for GBAR

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Lars Gehrmann; [2023]
    Nyckelord :;

    Sammanfattning : The main goal of the GBAR (Graviational Behaviour of Antihydrogen at Rest) experiment is to investigatethe gravitational effect on antimatter by measuring the classical free fall of an antihydrogen atom. The requiredpositrons are created by pair production inside a tungsten target and are moderated using a tungsten mesh. LÄS MER

  3. 2. Multi-ion radiotherapy treatment planning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Gustav Lidberg; [2023]
    Nyckelord :multi-ion radiotherapy; heavy-ion radiotherapy; carbon-ion radiotherapy; treatment planning; LET optimization;

    Sammanfattning : Multi-ion radiotherapy has been suggested as a new way to treat cancer, combining the radiological advantages of lighter and heavier ions in a single treatment to improve plan robustness and increase LETd in the target. To succeed, multi-ion radiotherapy requires a treatment planning system capable of computing dose for and optimising multi-ion treatment plans. LÄS MER

  4. 3. Ion Induced Particle Desorption From Self Supporting Nanomembranes : Influence of Different Geometries and Particle Types

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Jonas Beling; [2023]
    Nyckelord :ion; physics; ion physic; scattering; desorption; sputtering; jon; fysik; jonfysik;

    Sammanfattning : Nanoelectronics is a field undergoing rapid development, meaning knowledge of the materials and methods used in nano-scale systems is a driving force in the industry. Silicon is a well known material in nanoelectronics commonly used as a semiconductor and is therefore a good representative for nanomaterials in general. LÄS MER

  5. 4. Generation and Characterization of Intense Attosecond Pulses

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

    Författare :Marius Plach; [2020]
    Nyckelord :Attosecond physics; high-order harmonic generation; high harmonic generation; HHG; attosecond pulses; molecular dynamics; attosecond pulse generation; harmonic emission time delay; temporal reconstruction of attosecond pulses; strong field processes; Three-step model; RABBIT; Reconstruction of Attosecond Beating By Interference of Two-photon Transition; Terawatt Laser System; Intense XUV Beamline; XUV; LLC; Physics and Astronomy;

    Sammanfattning : Research on ultrafast dynamics in atoms and molecules requires short pulses. In order to resolve processes taking place on a femtosecond timescale sufficiently, these pulses require a duration on the attosecond time scale. LÄS MER

  7. 5. NEONSKYLTAR - ETT OSKYDDAT KULTURARV? Undersökning av skydd i KML och PBL

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Ola Sandberg; [2019-09-11]
    Nyckelord :Neon signs; heritage; built heritage; Swedish law;

    Sammanfattning : This thesis is an attempt to investigate the possibilities of protecting historic neon signs as heritage with some of the two Swedish laws that protect the built heritage. Kulturmiljölagen (SFS 1988:950) and Plan- och bygglagen (SFS 2010:900). LÄS MER
