1. Resonance Mitigation in the Attitude Control of a Flexible Large Solar Sail
University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikAbstract : This project is about the design process of a resonancemitigating algorithm for a large solar sail. The solar sail isa structure made up by four long booms in a cross patternwith suspended sails between the edges of the booms. Thespacecraft in this report is controlled using smaller rotatingsails at each tip of the booms. READ MORE

2. Optimization and Characterization of Luminescent Materials for the ESS Proton Beam Imaging System
University essay from Lunds universitet/Centrum för analys och syntesAbstract : Spallation sources such as European Spallation Source (ESS) produces neutrons by bombarding high-energy protons onto the target wheel. To determine the location of the proton beam a Proton Beam Imaging (PBI) system will be installed. READ MORE

5. Silicon surface passivation via ultra-thin SiO2, TiO2, and Al2O3 layers
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Energy traps at the silicon surface originating from discontinuities in the lattice is detrimental to the performance of solar cells. Acting as recombination centers, they offer a location where the charge carriers may easily return to their original energy band after excitation. READ MORE
