4. 2. High-sensitivity Radioactive Xenon Monitoring and High-accuracy Neutron-proton Scattering Measurements

   Author : Cecilia Johansson; Jan Blomgren; Nils Olsson; Allena Opper; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Monte Carlo simulations; MCNP; xenon detection; detector response; neutron detection; elastic scattering; differential cross section; Kärnfysik; Nuclear physics; Kärnfysik;

   Abstract : Two aspects of applied nuclear physics have been studied in this thesis; Monte Carlo simulations for high-sensitivity monitoring of radioactive xenon and high-accuracy neutron-proton scattering measurements for neutron physics applications and fundamental physics. The Monte Carlo simulations have been performed for two systems for detection of radioactive xenon, using the MCNP code. READ MORE

5. 3. Direct writing with an MeV proton beam: Development and Applications

   Author : Vaida Auzelyte; Kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; direct writing; beam control; Physics; Fysik; Teknik; Technological sciences; proton beam; lithography; Fysicumarkivet A:2006:Auželytė;

   Abstract : This thesis presents work aimed at the development and application of a new lithography system for direct material patterning with the MeV proton beam at the Lund Nuclear Microprobe (NMP) facility. MeV proton beams are advantageous for use as a patterning tool due to their deep and well defined penetration through matter and their highly local energy deposition. READ MORE

6. 4. 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.

7. 5. Proton trapping in the cellular acidic vacuolar compartment : lysosomal mechanisms in apoptosis/necrosis and iron chelation

   Author : Zhengquan Yu; Anders Isaksson; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Under ischemic conditions, a number of cytotoxic metabolic products are formed. Reactive oxygen species are known to be important mediators of progressive ischemic cell injury, and the synergistic damage to cells caused by the combination of such oxygen species and redox-active iron is well appreciated.
