  1. 6. Characterization of γ-rays at MAST

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Erik Blom; [2019]
    Keywords : fusion; MAST; MAST upgrade; neutron collimated flux monitor; neutron camera; gamma-ray;

    Abstract : The γ-ray characterizing possibility of the neutron collimated flux monitor (in short, Neutron Camera) at the Mega Ampere Spherical Tokamak (MAST) is explored. Typically used to monitor neutron emission, the Neutron Camera has excellent neutron/γ-ray discrimination properties and thus presents the opportunity to measure spatially and temporally resolved γ-ray emission - a possibility of an additional fusion diagnostics method with already existing equipment.

  3. 7. Quantification of I-131 Activity from Gamma Camera Images of Thyroid Cancer Patients

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Frida Westerbergh; [2019]
    Keywords : Physics and Astronomy;

    Abstract : BACKGROUND: Radioiodine (131I) has been used in thyroid cancer treatments for many years, and has demonstrated good results with regards to disease management. Radioiodine therapy is however partially empirical, as not very much is known concerning radiation dosimetry. READ MORE

  4. 8. Simulation of Scientific VHF Telemetry Data for the French Payload of the SVOM Satellite

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Florian Reiner; [2019]
    Keywords : ;

    Abstract : The Space Variable Objects Monitor (SVOM) is a future French-Chinese satellite mission which is dedicated to the observation and characterisation of Gamma Ray Bursts (GRBs). When a GRB is detected by the satellite, the position and initial characterisation data are transmitted to ground via a VHF telemetry link, in order to trigger immediate follow-up observations of the transient GRB afterglow by ground-based telescopes.

  5. 9. Studies of the orbital background noise and the detector characteristics for the MeVCube mission

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Eleni Athanasiou; [2019]
    Keywords : space instrumentation; gamma-ray instrumentation; MeVCube; space environment effects; orbital background noise; detector characteristics; signal generation; weighting potential simulations; electric field simulations;

    Abstract : A space camera is a promising candidate to address the non-stop rising interest for astrophysics research in the Compton regime. The MeVCube mission is intended to be launched in 2022, hosting an on-board Compton Camera. READ MORE

  6. 10. Dosimetry of ionizing radiation with an artificial neural network : With an unsorted, sequential input

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Ivan Appelsved; [2018]
    Keywords : Artificial neural network; recurent neural network; ionizing radiation; dosimetry; timepix3 radiation camera;

    Abstract : In this thesis the verification of a neural network’s proficiency at labeling ionizing radiation particles from the unsorted output of a timepix3 camera is attempted. Focus is put on labeling single particles in separate data sequences with slightly preprocessed input data. READ MORE
