1. 1. Improving polarizing neutron optics by introducing 11B4C as interlayers

   University essay from Linköpings universitet/Tunnfilmsfysik

   Author : Martin Falk; [2023]
   Keywords : Thin film multilayers; Neutron optics; Neutron polarization;

   Abstract : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. READ MORE

3. 2. Phosphonium Ionic Liquids at Interfaces: NR studies of interfacial electro-responsiveness

   University essay from KTH/Kemi

   Author : Filip Mehler; [2022]
   Keywords : Neutron reflectometry; Ionic liquid; Phosphonium Ionic Liquid; Tribology; Neutronreflektometri; Jonvätskor; fosfoniumjonvätskor; tribologi;

   Abstract : Fosfoniumjonvätskor har tidigare studerats som potentiella nya avancerade smörjmedel på grund av sina unika fysikaliska egenskaper och fördelar jämfört med både traditionella smörjmedel och andra typer av jonvätskor. Dessa studier har uppvisat lovande resultat med avseende på reducering av nötning och friktion såväl som kontroll av dessa parametrar med en pålagd elektrisk potential. READ MORE

4. 3. 2D Neutron Imaging with 10B-Based Multi-Blade Detector

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

   Author : Tõnu Ilves; [2018]
   Keywords : thermal; neutron; imaging; 2D; Multi-Blade; detector; boron; boron-10; nuclear physics; multi wire proportional chamber; digitizer; ESS; European Spallation Source; surface study; reflectometry; Physics and Astronomy;

   Abstract : In the field of thermal-neutron imaging, the Multi-Blade detector concept and design, being developed for the upcoming European Spallation Source in Lund, Sweden, is unique. The current report presents, for the first time, the neutron-imaging capabilities of a boron-10-based Multi-Blade thermal-neutron detector, measured at a reflectometry instrument at Rutherford Appleton Laboratory in Oxfordshire, England under high spallation neutron flux.

5. 4. Neutron Reflectometry performed on an Iridium Sample using the Multi-Blade Detector

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

   Author : Alexander Backis; [2018]
   Keywords : Technology and Engineering; Physics and Astronomy;

   Abstract : The current thesis presents the results from a neutron reflectometry analysis performed on data collected at ISIS in Rutherford Appleton Laboratories, England, in October 2017. The CRISP instrument was used and the Multi-Blade incorporated as a detector. This was the first attempt ever to use the Multi-Blade in this type of measurement. READ MORE
