1. 1. Identification of Neutrons Using Digitized Waveforms

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

   Author : Rasmus Kjær Høier; [2019]
   Keywords : Digitizer; neutron; gamma-ray; pulse-shape discrimination; CNN; convolutional neural network; charge comparison; time of flight; source-testing facility; STF; Physics and Astronomy;

   Abstract : The advantages of performing neutron-tagging measurements using a waveform digitizer are explored. An existing analog setup consisting of modular crate electronics at the Source-Testing Facility at the Division of Nuclear Physics in Lund, Sweden has been digitally replicated. READ MORE

3. 2. Two-Dimensional Radiation Field Map of a Be-based Source

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

   Author : Henrik Söderhielm; [2017]
   Keywords : Nuclear Physics Particle Detectors Neutrons Gamma Rays European Spallation Source Lund University; Physics and Astronomy;

   Abstract : The aim of this project was to measure the profile of the radiation exiting an aperture of the Aquarium at the Source Testing Facility at the Division of Nuclear Physics at Lund University. So far, the outgoing beam of radiation at the aperture of the Aquarium has been assumed to be uniform. READ MORE

4. 3. Ecocertifications and quality labels : For whom and why, in the case of Laponia.

   University essay from Uppsala universitet/Institutionen för kulturantropologi och etnologi

   Author : Anna Engberg; [2017]
   Keywords : Laponia; World Heritage; tourism; ecocertifications; quality markings; eco tourism;

   Abstract : Abstract There are a lot of ecocertifications in Sweden for a variety of different categories; for example the Swan, which is a label for both hotels and products; KRAV, a label for farms and what farms pro- duce; Nature’s Best, a label for tourist adventures; the Sápmi Experience, a newly developed label for Sámi tourism, and The Green Key, a certification offered by Håll Sverige Rent for hostels, ho- tels, mountain cabins and camping grounds. Nature’s Best and the Green Key I have chosen as the focus for this paper, because they are the most relevant for my research. READ MORE

5. 4. The Radiological Footprint of a Be-based Neutron Source

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

   Author : Sharareh Koufigar; [2015]
   Keywords : Physics and Astronomy;

   Abstract : The radiological footprint of a Be-based neutron source embedded within the Aquarium of the Source-Testing Facility (STF) at the Division of Nuclear Physics at Lund University will soon be carefully mapped. As a precursor to this measurement program, neutron and gamma-ray energy spectra at beamport apertures have been measured using 3He and LaBr3(Ce) (cerium-activated lanthanum bromide) detectors.

6. 5. Fabrication and Characterization of Sculptured Thin Silver Films

   University essay from Tillämpad optik; Tekniska högskolan

   Author : Johan Gustafson; [2013]
   Keywords : Glancing angle deposition; GLAD; sculptured thin films; STF; Silver thin films; nanocolumns; nanospirals;

   Abstract : In this work samples with silver nanocolumnar structures were successfully fabricated by glancingangle deposition. From SEM investigations of the samples it is concluded that distinct andseparated nanocolumns can be grown without pre-patterned substrates using this method (givensuitable deposition conditions).
