  1. 21. A prototype backscattering neutron time-of-flight spectrometer

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Sakari Teerikoski; [2015]
    Keywords : ;

    Abstract : Measuring neutron energies is an essential task in fusion research. The time-of-flight (TOF) of neutrons moving a known distance can be used to determine these energies. Slower neutrons have longer TOFs for fix flight paths. Neutrons are slowed down when they backscatter. READ MORE

  2. 22. Developement of a portable β-­‐ spectrometer for in situ measurements of Sr-­‐90 and Y-­‐90 using a plastic scintillator and a silicon photomultipler (SiPM).

    University essay from Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/Sjukhusfysikerutbildningen

    Author : Daniel Krona; [2015]
    Keywords : Medicine and Health Sciences;

    Abstract : In the event of a nuclear weapon detonation or a power plant accident radionuclides will deposit on the ground. It is then important to identify and quantify the radionuclides to obtain information necessary for radiation protection efforts like relocation and decontamination. READ MORE

  3. 23. Evaluation of accuracy in simultaneous dual-radionuclide activity quantification in preclinical instruments – scintillation counter, digital autoradiography and micro-SPECT/CT

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Jonas Ahlstedt; [2012]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: The development and optimization of methods for multi-radionuclide measurements in preclinical in vivo and ex vivo SPECT imaging could potentially improve studies in which more than one pharmaceutical is being investigated. The aim of this study is to quantitatively compare and evaluate different methods for these types of measurements using three different modalities – a small animal SPECT/CT, a scintillation counter and a digital autoradiography instrument.

  4. 24. Bremsstrahlung Luminosity Monitoring for SCRIT Project (Report part II)

    University essay from Institutionen för fysik och astronomi

    Author : Niklas Lundkvist; [2011]
    Keywords : ;

    Abstract : The purpose of the SCRIT project is to determine size and shape of short-lived and rarely-produced nuclei by elastic electron scattering, which is the best probe for the structure studies, for the first time. In traditional electron scattering, a solid target having an order of 1023 nuclei/cm^2 is normally used, which is not possible for short-lived and rarely-produced nuclei. READ MORE
