    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. 2. CARVING STEEL

    University essay from Göteborgs universitet/Steneby - Institutionen för Konsthantverk och Design

    Author : Arttu Halkosaari; [2020-09-25]
    Keywords : Forging; Tactility; Touch; Plasma cutting; Blacksmith; Texture; Contrast;

    Abstract : This exam project will be a conclusion for a long working process which started a year and a half ago. During this time, I have developed my own way of working with a plasma cutter and use that with different forged forms to create sculptures with varying textures. READ MORE

  4. 3. Passivation of Gallium Arsenide Nanowires for Solar Cells

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Austin Irish; [2019]
    Keywords : nanowires; semiconductors; solar cells; photovoltaics; passivation; electronics; chemistry; polymers; hydrazine; plasma; gallium; arsenic; iii-v; epitaxy; photoluminescence; time-resolved; spectroscopy; Physics and Astronomy;

    Abstract : A strategic and diverse set of passivation methods for gallium arsenide nanowires wasstudied. Using a time-resolved photoluminescence setup at100 Kand300 K, the radiativerecombination of charge carriers was resolved on a picosecond time scale. READ MORE

  5. 4. In-line Phase-contrast Tomography using Betatron X-rays Produced by a Laser-Plasma Accelerator

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

    Author : Kristoffer Svendsen; [2017]
    Keywords : source size; x-ray; in-line; phase-contrast; phase contrast; LWFA; laser wakefield acceleration; tomography; diffraction; diffraction simulation; laser-plasma acceleration; Physics and Astronomy;

    Abstract : X-ray phase-contrast imaging is a powerful technique that allows great resolving power for low absorbing samples, such as biological tissue. This method relies on measuring the phase shift induced by the sample instead of the absorption traditional radiography relies on. READ MORE

  6. 5. Fatigue Life Assessment of Cut Edges in High Strength Steel

    University essay from KTH/Lättkonstruktioner

    Author : Ilona Barmicho; [2016]
    Keywords : ;

    Abstract : The interests in more effective and lighter structures have increased the use of high strength steels for higher performances. Plate materials are optimized so thinner structures and higher material strengths are reached, this leads to the cut quality might be a new issue. READ MORE
