  2. 16. A Fast Pixelated Thermal-Neutron Detector

    Author : Emil Rofors; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SoNDe; thermal-neutron detector; GS20 scintillator; Li-glass; H12700A MAPMT; position-dependent response; alpha-particle; proton; deuteron; neutron; ESS; SKADI;

    Abstract : This thesis presents the study of a position-sensitive scintillation-based detector called the Solid-State Neutron Detector (SoNDe). SoNDe is being developed for cold- and thermal-neutron detection at the small-angle neutron scattering (SANS) instrument SKADI at the European Spallation Source (ESS), currently under construction in Lund, Sweden.

  4. 17. The Anticoincidence Shield of the PAMELA Satellite Experiment

    Author : Silvio Orsi; KTH; []
    Keywords : astrophysics; particle physics; antimatter; organic scintillators;

    Abstract : The PAMELA space experiment is scheduled for launch towards the end of 2004 on-board a Russian Resurs DK1 satellite, orbiting Earth at an altitude of 300– 600 km. The main scientific goal is a study of the antimatter component of the cosmic radiation. The semipolar orbit (70. READ MORE

  5. 18. Accelerators for Physics Experiments : From Diagnostics and Control to Design

    Author : Elena Wildner; Thomas Lindblad; Mikael Eriksson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astroparticle physics; Astropartikelfysik;

    Abstract : This thesis develops techniques of control-methods, optimization, and diagnostics of accelerator equipment and the produced particle beams with emphasis on the Large Hadron Collider (LHC) project at CERN. From a solid knowledge of the characteristics of the manufactured accelerator equipment gained from in-depth measurements and analysis of measured data, a link to an enhanced equipment design can be made.

  6. 19. Effective Charges in Nuclei in the vicinity of 100Sn

    Author : Andreas Ekström; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The shell structure of atomic nuclei far from the line of beta-stability and the properties of the nucleon-nucleon interaction in exotic isotopes are not well known. The development of radioactive ion beams (RIBs) puts certain unexplored regions of the nuclear chart within reach of detailed experimental investigations. READ MORE

  7. 20. Neutron Halo Nuclei

    Author : Katarina Wilhelmsen Rolander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In light nuclei close to the neutron drip-line a spatially extended neutron distribution, the neutron, halo occurs. This is due to the relatively small binding energy of the last neutrons which makes possible quantum mechanical tunnelling of the last neutron(s) far away from the nuclear core. READ MORE
