    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; cryogenic target; pellet; pellet target; pellet tracking; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

    Sammanfattning : The development of a system for optical tracking of frozen hydrogen microsphere targets (pellets) was done. It is intended for the upcoming hadron physics experiment PANDA at FAIR, Darmstadt, Germany. LÄS MER

  3. 2. On a Hydrogen Pellet Target for Antiproton Physics with PANDA

    Författare :Örjan Nordhage; Ulrich Wiedner; Eberhard Widmann; Uppsala universitet; []
    Nyckelord :Nuclear physics; PANDA; Internal target; Pellet target; Beam-target interaction; Vacuum; Tracking; D-meson decay length; Kärnfysik;

    Sammanfattning : The PANDA experiment is a part of the future FAIR accelerator facility and will study the strong interaction by detecting the reaction products from antiproton-proton annihilations in a near full solid-angle configuration. One option for the internal proton target in PANDA is frozen micro-spheres of hydrogen, so-called pellets. LÄS MER

  4. 3. Towards a realistic hyperon reconstruction with PANDA at FAIR

    Författare :Adeel Akram; Karin Schönning; Michael Papenbrock; Carl Nettelblad; Marek Jacewicz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hyperon; Extended Target; Tracking; PANDA; FAIR; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Sammanfattning : The goal of the PANDA (anti-Proton ANnihilation at DArmstadt) experiment at FAIR (Facility for Anti-proton and Ion Research) is to study strong interactions in the confinement domain. In PANDA, a continuous beam of anti-protons () will impinge on a fixed hydrogen (p) target inside the High Energy Storage Ring (HESR), a feature intended to attain high interaction rates for various physics studies e.

    Sammanfattning : Inflammation plays an important role in atherosclerosis. One of the most potent pro-inflammatory cytokines is tumor necrosis factor-alpha (TNF-a), a cytokine identified to have a pathogenic role in chronic inflammatory diseases such as rheumatoid arthritis (RA). LÄS MER

  7. 5. Retrofitting CHP Plant and Optimization of Regional Energy System

    Författare :Song Han; Jinyue Yan; Eva Thorin; Mats Westermark; Mälardalens högskola; []
    Nyckelord :annual performance; combined heat and power; drying; ethanol; integration; part-load.; årliga prestation; kraftvärme; torkning; etanol; integration; del-last.; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The use of biomass-based combined heat and power (CHP) plants is considered by the EU administration to be an effective way to increase the use of renewables in the energy system, to reduce greenhouse gas emissions and to alleviate the dependency on imported fossil fuels. At present in Sweden, most of the CHP plants are operated in part-load mode because of variations in heat demand. LÄS MER
