  1. 1. Data Reduction and Analysis with the MPRu instrument for Neutron Emission Spectroscopy at JET

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Steven Hendrik Bijl; [2023]
    Nyckelord :Fusion; JET; MPRu;

    Sammanfattning : This research project centres on advancing data analysis techniques using the Magnetic Proton Recoil Upgrade Neutron Spectrometer (MPRu) for neutron emission spectroscopy during the deuterium tritium experimental campaign (DTE2) at the Joint European Torus (JET). The study aimed to address three pivotal questions, each with implications for optimizing data accuracy, quality, and utility. LÄS MER

  3. 2. Evaluation of the treatment planning system decimal ElectronRT and custom-made bolus for FLASH-irradiation

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Mizgin Coskun; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: The novel external beam therapy technique using ultra-high dose rates known as FLASH has become known for its normal tissue sparing effect. Currently in Lund, veterinary clinical trials are carried out on canine patients using electrons with ultra- high dose rates. LÄS MER

  4. 3. Birch leaf carbon dots: characterization and application in a light-emitting electrochemical cell

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Märta Gregorsson; [2022]
    Nyckelord :carbonized polymer dot; carbon dots; light-emitting electrochemical cell; pheophytin; solid-state luminescence; self-quenching; aggregation-caused-quenching; host-guest system;

    Sammanfattning : A new rising star in the carbon nanomaterial family is carbon dots. Carbon dots have received great attention due to their excellent luminescence and low toxicity. In this project, a new carbon dot derived from birch leaves is studied and characterized. LÄS MER

  5. 4. Simulations of a back scatter time of flight neutron spectrometer for the purpose of concept testing at the NESSA facility.

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Benjamin Eriksson; [2018]
    Nyckelord :fusion; JET; Geant4; NESSA; NESSA facility; back scatter tof; tof; time of flight; spectrometer; neutron; ITER; Monte Carlo; simulation;

    Sammanfattning : A back scatter time of flight neutron spectrometer consisting of two scintillation detectors is simulated in Geant4 to examine whether it is possible to perform a proof of concept test at the NESSA facility at Uppsala University. An efficiency of ε = 2.45 · 10^-6 is shown to be large enough for a neutron generator intensity of 1. LÄS MER

  7. 5. Stacked Dual Narrowband Organic Near-Infrared Photodetectors

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Yazhong Wang; [2017]
    Nyckelord :Near-infrared; photodetectors; CT states; Fabry-Perot resonant cavity; resonant cavity enhancement; tunability; full width at half maximum;

    Sammanfattning : Compared with the detector devices made of inorganic semiconductors, organic photodetectors are granted with additional strengths, such as flexibility, high scalability and bio-compatibility. However, in the family of organic optoelectronic devices, the detectors that are capable of detecting photons at two or multiple specific wavelengths are still missing. LÄS MER
