  1. 1. Crystallinity of Sputtered TiO2 Thin Films: a Study of the Heating and Plasma Influence on the Growth

    University essay from

    Author : oussama ezzaher; [2023]
    Keywords : ;

    Abstract : AbstractHigh-Power Impulse Magnetron Sputtering (HIPIMS) of TiO2 thin films enhances their photocatalyticproperties compared to the films prepared by standard sputtering methods, especially when no substrateheating is employed. With no heating, the coatings present an amorphous structure that benefits from theionization of the sputtered flux granted by HiPIMS, with respect to their photocatalytic performance. READ MORE

  3. 2. Use of the JET pedestal database to assess the role of ion temperature and plasma rotation on the discrepancy between ideal peeling-ballooning model and experimental data

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

    Author : Max Eichenberger; [2022]
    Keywords : Nuclear fusion; Joint European Torus JET ; H-mode; pedestal; Edge-localized-modes ELMs ; Peeling-Ballooning; relative shift; ion temperature; plasma rotation; Kärnfusion; JET Joint European Torus ; H-läge; piedestal; ELM Edge Localized­Modes ; peeling-ballooning; relativ förskjutning; jontemperatur; plasmarotation;

    Abstract : Next-generation and present fusion devices such as the Joint European Torus (JET) aim for plasma operations in H-mode, a plasma regime with high confinement and low loss of energy and fuel that results from a barrier for heat and particle transport at the plasma edge, the pedestal. Due to steep gradients of the density, temperature and pressure profiles, the pedestal experiences instabilities called Edge-localized-modes (ELMs) which lead to large fluxes of heat and particles that might damage machine components.

  4. 3. Improving the wire boom deployment system used on SPIDER-2 : Increasing reliability, robustness and ease of assembly for a wire boom deployment system

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

    Author : Jona Sandgren; [2021]
    Keywords : Space; Probe; Wire boom; Deployment; Improvement; Test; Rymden; Prob; Trådbom; Utfällning; Förbättring; Test;

    Abstract : This project deals with the improvement of a wire boom deployment system to be used on a proposed Rocket Experiments for University Students (REXUS) mission. The system to be improved was previously used on the Small Payload for Investigation of Disturbances in Electrojet by Rockets (SPIDER-2) mission and the objective was to make that system more robust and reliable as well as easier to assemble.

  5. 4. Variability of Io’s Aurora and the Moon’s Footprint on Jupiter

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

    Author : Jens Eilers Bischoff; Sebastian Jovancic; [2020]
    Keywords : Alfv ́en waves; Aurora; HST; Io; Jupiter; Plasma;

    Abstract : We study the variability of intensity of Io’s aurora asa function of Jupiter’s rotation measured in system III longitude.The far-ultraviolet intensity of Io’s aurora was measured by theHubble Space Telescope (HST) using the FUV-MAMA photondetector of the STIS. READ MORE

  6. 5. Temporal Characterization and Intensity Contrast Improvement of Few-cycle Laser Pulses

    University essay from Umeå universitet/Institutionen för fysik

    Author : Xiaoying Zhang; [2019]
    Keywords : ;

    Abstract : Due to the unique combination of properties of high intensity and few optical cycle pulse duration, the ultrashort laser pulses have widespread applications in pump-probe spectroscopy and laser-plasma interaction. Correspondingly, it is critical to precisely measure the electric field in the temporal or spectral domain. READ MORE
