  1. 11. Constructing and commissioning of a Multi-Grid neutron detector prototype for the European Spallation Source

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

    Author : Rebecka Wahlén; [2022]
    Keywords : Physics and Astronomy;

    Abstract : A prototype of a novel 10B-based neutron detector called the Multi-Grid detector has been constructed, tested and commissioned for the European Spallation Source (ESS). The detector is constructed after the specifications set by the CSPEC instrument at ESS and is therefore called the CSPEC Multi-Grid detector. READ MORE

  3. 12. Exploring the Diversity of Exoplanets

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Rebecka Svensson; [2021]
    Keywords : Exoplanets; Super-Earth; Sub-Neptune;

    Abstract : The search for extrasolar planets had been ongoing for many years when Mayorand Queloz discovered 51 Pegasi b in 1995. It was a giant gas planet similar to Jupiter, but with a larger radius and of only half of Jupiter’s mass. Theso called Hot Jupiter was observed to orbit its host star 7 times closer thanMercury is orbiting the Sun. READ MORE

  4. 13. Application of mass defect filtering and statistical analysis for non-target data mining of gas and soot data from a study testing different firefighting methods

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Danielle Ydstål; [2020]
    Keywords : ;

    Abstract : Due to the high temperatures during a fire event, a large variety of compounds are formed or released from burning materials, all of which have a varying degree of environmental effects. In an incidental fire there are several variables that are important for which and how much combustion products that are formed, including the burning material, ventilation (presence of air), and temperature.

  5. 14. Influence of fuel mix on mass balance of Cl, S, and K in a long rotary kiln

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Simon Nilsson; [2019]
    Keywords : ;

    Abstract : Lime is a material with a wide range of applications including land improvement, water treatment as well as the paper-, steel-, and cement industry. Annual worldwide production was estimated at 350 Mt/year for 2016 and 2017 and the production is responsible for a large contribution of the greenhouse gas CO2 to the atmosphere, contributing to global warming.

  6. 15. Observing phase changes in real time on ultrathin Iron oxide surfaces

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

    Author : Harald Wallander; [2019]
    Keywords : CO oxidation; platinum; iron oxides; Physics and Astronomy;

    Abstract : Studying catalysts under such non-equilibrium conditions is a step towards approaching more realistic reaction conditions for working catalysts. Reactivity during phase changes of ultra-thin FeO2 films grown on Pt(111) are studied in situ with Ambient Pressure X-ray Photo Emission Spectroscopy and Quadrupole Mass Spectrometry, while running the CO oxidation reaction at 160°C and 0:6 mbar.
