  5. 3. Dosimetry and radiation quality in fast-neutron radiation therapy : A study of radiation quality and basic dosimetric properties of fast-neutrons for external beam radiotherapy and problems associated with corrections of measured charged particle cross-sections

    Author : Jonas Söderberg; Gudrun Alm Carlsson; Crister Ceberg; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neutron; Dosimetry; Radiotherapy; Monte Carlo; Microdosimetry; Cross-section; RBE; LET; Energy-loss corrections; Radiological physics; Radiofysik;

    Abstract : The dosimetric properties of fast-neutron beams with energies ≤80 MeV were explored using Monte Carlo techniques. Taking into account transport of all relevant types of released charged particles (electrons, protons, deuterons, tritons, 3He and α particles) pencil-beam dose distributions were derived and used to calculate absorbed dose distributions.

  6. 4. Searches for Dark Matter with IceCube and DeepCore : New constraints on theories predicting dark matter particles

    Author : Matthias Danninger; Klas Hultqvist; Patrick Decowski; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark matter; neutrinos; neutrino telescopes; IceCube; DeepCore; dark matter experiments; fysik; Physics;

    Abstract : The cubic-kilometer sized IceCube neutrino observatory, constructed in the glacial ice at the South Pole, searches indirectly for dark matter via neutrinos from dark matter self-annihilations. It has a high discovery potential through striking signatures. READ MORE

  7. 5. Thermal Plasmonic Metasurfaces

    Author : Gustav Edman Jönsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Plasmonic materials can form viable optical absorbers that offer new possibilities for device designs as they potentially have large optical cross-sections with readily tuned spectral positions and widths. Applications for such materials include heat generation via optical absorption. READ MORE
