6. Plume-Spacecraft Interaction Analysis : Study on the Plume Effects of Hall-Effect Thrusters (HET) and High-Efficiency Multistage Plasma Thrusters (HEMPT).
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Plume-spacecraft interactions play an important role in the performance and integrity of spacecraft during their missions in space. The study encompasses a thruster’s plume simulation and its impact on spacecraft geometries to understand and predict the effects and consequences of the impingement on spacecraft surfaces, such as erosion, contamination, forces, and torques.

7. Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Aberrations to the wavefront of a laser beam reduce the quality of the focal spot and are generally undesired. This project is aimed at determining the aberrations of laser beams by using a phase retrieval algorithm and to show that it is possible to correct the aberrations with a spatial light modulator to optimize the focal spot.

8. Distortion and attenuation free gain-assisted Superluminal Propagtion in a Rare-Earth Doped Crystal
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : A light pulse that travels through a narrow spectral window, i.e. a frequency range of low absorption, within a strongly absorbing frequency range will be delayed due to strong dispersion. READ MORE

9. Quantum state tomography of attosecond electron wavepackets
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : In this master thesis, a broad theoretical description is done of a novel quantum state tomography protocol called KRAKEN. This protocol is meant for the determination of the density matrix of an electronic state created by absorption of XUV radiation in the vicinity of a Fano resonance. At first, a description of the KRAKEN protocol is provided. READ MORE

10. Adaption of Inertial Confinement Fusion Resultsto Spherical Plasma Expansion at Comets
University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenAbstract : Recent missions to solar system comets, such as ESA's Rosetta mission, raise interest for models and descriptions of their plasma environment. The interaction with various space phenomena such as stellar wind make the construction of an analytical description difficult. READ MORE
