  1. 26. Dark matter electron interactions in detector materials

    Författare :Einar Urdshals; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; effective theory; direct detection;

    Sammanfattning : Dark Matter (DM) makes up 85% of the matter content of the universe, and its gravitational effects are seen on scales ranging from that of cosmology to that of galactic astrophysics. The nature of DM is, however, unknown. Studying DM in the lab is key to understanding its nature. LÄS MER

  3. 27. In situ measurements of radionuclide concentration in soil : An investigation into detector properties and methods

    Författare :Johan Kastlander; Christoph Bargholtz; Mats Isaksson; Stockholms universitet; []
    Nyckelord :In situ gamma-ray spectrometry; LaBr3; CdTe; Cs-137; soil samples; fysik; Physics;

    Sammanfattning : In case of a release of radioactive nuclides into the environment it is necessary to  have reliable methods to estimate the potential effect on people and the ecosystem. In this context the total activity deposited, the elemental composition and the depth distribution are of importance. LÄS MER
