  1. 16. Initial Characterization of a Pixelated Thermal-Neutron Detector

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

    Author : Amanda Jalgén; [2017]
    Keywords : Neutron; detector; spallation; scintillator; photomultiplier tube; Physics and Astronomy;

    Abstract : The purpose of this project was to develop a better understanding of the re- sponse of a pixelated thermal-neutron detector, which will be used as a thermal- neutron detector at one of the beam lines at the European Spallation Source in Lund, Sweden. The detector consists of a thin Lithium6-glass scintillator, a multi-anode photomultiplier tube and associated read-out electronics. READ MORE

  3. 17. Time-Resolved Photoluminescence Studies of InGaP Nanowires for Improving the Internal Quantum Efficiency

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Lert Chayanun; [2017]
    Keywords : Physics and Astronomy;

    Abstract : Semiconductor Nanowires are promising building blocks for advanced optoelectronic devices since their small diameter give rise to quantization effects. The small diameter also makes them susceptible to non-radiative recombination due to surface states. READ MORE

  4. 18. 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

  5. 19. Trace element analysis based on neutron activation with coincident gamma ray detection

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

    Author : Jessica Delgado; [2017]
    Keywords : scintillator detectors; gamma ray; gamma radiation; spectrometer; neutron activation analysis; trace element; Physics and Astronomy;

    Abstract : In this work, six soil samples have been analyzed. The samples come from different sedimentary layers on Earth. They were previously studied with the objective to find the trace concentration of iridium, to correlate the increased concentrations of iridium with meteorite impacts that have occurred on Earth.

  6. 20. Development and study of luminescent bolometers for neutrino physics

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Yann Gimbal-Zofka; [2017]
    Keywords : Neutrinoless double beta decay; bolometer; scintillating bolometer; leptogenesis; neutrino; cryostat; radioactivity;

    Abstract : This Master thesis aims at designing, assembling and operating a prototypal luminescentbolometer containing a candidate with high Q-value (116Cd and 100Mo)for the study of the neutrinoless double- decay. The crystal is scintillating (with 116CdWO4 and Li2MoO4 compounds). READ MORE
