1. Investigation of Ion Extraction Anomalies at TwinEBIS
University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenAbstract : The electron beam ion source REXEBIS at CERN-ISOLDE delivers highly-charged ra- dioactive ions for post-acceleration in the HIE-ISOLDE LINAC. Research and develop- ment of components for electron beam ion sources is carried out at the TwinEBIS test stand, currently equipped with a Brillouin electron gun called MEDeGUN. READ MORE

2. Simulations of the Tenuous Upper Atmospheres of Exoplanets
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. READ MORE

3. 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.

4. Electron Acceleration at Earth Bow Shock
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Electrons accelerating in shock events occur oftenin outer space, for example in supernovas and the poles of blackholes, and are of high interest to physicists and other researchers.The technology to take a closer look at events that far awaydoes not exist yet, but luckily we can observe similar events inplaces where the Earth’s magnetic fields and particle streamsfrom the Sun meet.

5. Relativistic attosecond electron pulses by laser wakefield acceleration
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : The search for cheaper and more compact accelerators has led to the development of laser-driven plasma-based accelerators. In comparison to conventional particle accelerators, the plasma-based accelerator is inherently insensitive to the breakdown of the acceleration structure and therefore greater accelerating fields can be obtained.
