  2. 21. Mini-Jet Production in Proton-Antiproton Interactions and Particle Production in Heavy-Ion Collisions

    Author : Haiqiao Wang; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; proton antiproton interaction; Quark-gluon plasma; dynamical fluctuation; intermittency; limiting fragmentation; intranuclear cascading; target fragmentation; heavy-ion collision; image processing; mini-jet; Nuclear physics; Kärnfysik; Fysicumarkivet A:1997:Wang;

    Abstract : The thesis is based on the data analysis and detector development of the EMU01/CERN, E863/BNL and UA1/CERN experiments. Particle fluctuations are studied with the scaled factorial moments in the fragmentation region of oxygen-induced emulsion interactions from 3.7 to 200 A GeV. READ MORE

  4. 22. Radionuclide Production with PET Cyclotrons, Applications and Preclinical Experiments

    Author : Jonathan Siikanen; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radionuclide production; Solid target; Water target; Cyclotron; PET; SPECT; 18F; 89Zr;

    Abstract : Nuclear medicine is based on the radiotracer principle of George de Hevesy and the magic bullet concept by Ehrlich and focuses on the diagnosis, the treatment of diseases and the investigation of normal states within the human body using radiopharmaceuticals. A radiopharmaceutical is an atom or a chemical compound in which one or several atoms are replaced with a radionuclide. READ MORE

  5. 23. Quark Distributions and Charged Higgs Boson Production : Studies of Proton Structure and New Physics

    Author : Johan Alwall; Gunnar Ingelman; Johan Rathsman; Dieter Zeppenfeld; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; quark distributions; parton density functions; proton structure; strange quark; intrinsic charm; charged Higgs boson; supersymmetry; NuTeV; LHC; parton showers; matrix element; elementary particle physics; Fysik; Physics; Fysik;

    Abstract : The Standard Model describes all elementary particles known today, but at larger energies it will have to be complemented with new particles and interactions. To be able to distinguish new physics at proton colliders such as LHC at CERN, it is essential to have an appropriate description of the colliding protons and their interactions. READ MORE

  6. 24. A Methodology to Control the Microstructure of Plasma Sprayed Coatings

    Author : Martin Friis; Materialteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materialteknik; Materiallära; Process map; Plasma spraying; process window; Thermal Barrier Coating; Zirconia; DPV2000; particle temperature; Material technology; particle velocity;

    Abstract : The aim of this thesis is to enhance the overall understanding of the plasma spray process and increase control and reproducibility of the coating properties. This was performed by establishment of relationships between controllable process parameters, in-flight properties of the injected particles (velocity and temperature), and microstructure properties.
