1. Characterization of surface defects caused by ultrasonic cleaning of aluminium
University essay from Uppsala universitet/Tillämpad materialvetenskapAbstract : This master thesis studies the behaviour of two aluminium alloys in ultrasonic cleaning at two different intensities, as well as the effect of a cleaning solution, Formula 815 GD-NF on the same surface have been studied with respect to surface roughness and material composition. Methods like Light Optical Microscopy (LOM), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and 3D topography using white light interferometry (VSI) was used to study the surface and material composition.

2. Seeing Stars - Intensity Interferometry in the Laboratory and on the Ground
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : Context Since the time of Tycho Brahe astronomy has been an observing science defined by the quality of its instrumentation. The introduction of primitive telescopes by Galileo in 1609 began a period of development of ever-larger telescopes with greater measuring precision. READ MORE

3. Pulsed Laser Beam Quality Assessment via Phase Retrieval
University essay from Lunds universitet/AtomfysikAbstract : In the search for a better understanding of the fundamental nature of the atom, the development of femtosecond pulsed laser sources has opened up for many applications, in particular in time-resolved physics. For many of those, like the generation of attosecond pulses through high-order harmonic generation, high intensity is needed and the quality of the beam is a critical factor. READ MORE

4. Interferometric Charecterization of Supersonic Gas-Jets for Laser Wakefield Acceleration
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : The Multi-Terawatt laser at the LLC (Lund Laser Centre) is used to accelerate particles using laser wakefield acceleration. Laser wakefield acceleration is a particle acceleration method that utilizes intense electric fields in plasma created by high intensity laser pulses when passing through gas. READ MORE
