  1. 11. Development of Neutron Emission Spectroscopy Instrumentation for Deuterium and Deuterium-Tritium Fusion Plasmas at JET

    Författare :Luca Giacomelli; Jan Källne; Thomas Sangster; Uppsala universitet; []
    Nyckelord :Nuclear physics; neutron spectroscopy; MPRu; TOFOR; JET; Radio frequency heating; Count rate; Kärnfysik;

    Sammanfattning : The study of high power fusion plasmas at the JET tokamak has been further enhanced through the development of instrumentation for neutron emission spectroscopy (NES) measurements. This has involved the upgrade of the magnetic proton recoil (MPR) spectrometer used for deuterium-tritium plasmas earlier so that the MPRu can now be also employed for deuterium (D) plasmas. LÄS MER

  3. 12. Compact Liquid-Jet X-Ray Sources

    Författare :Oscar Hemberg; KTH; []
    Nyckelord :liquid-jet; x-ray; EUV; plasma; electron beam; source;

    Sammanfattning : This thesis describes the development, characterization andoptimization of compact, high-brightness, liquid-jet-targetx-ray sources. Two different source types have been developedfor different wavelength regions and applications. LÄS MER

  4. 13. The evolution of TOFu : Developing and utilizing neutron time-of-flight spectrometry of deuterium and tritium fusion plasmas at JET

    Författare :Benjamin Eriksson; Göran Ericsson; Anders Hjalmarsson; Sean Conroy; Jacob Eriksson; Luka Snoj; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fusion; plasma diagnostics; neutron spectrometry; time-of-flight; TOFOR; JET; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : Considerable effort has been invested in attempting to generate electricity from the energy released in controlled thermonuclear fusion reactions, with a European fusion research roadmap stretching beyond 2050. Our current endeavors may culminate in a virtually inexhaustible, low-carbon energy source for future generations. LÄS MER

  5. 14. Λ/K0s Associated with a Jet in Central Pb–Pb Collisions at √sNN = 2.76 TeV Measured with the ALICE Detector

    Författare :Tuva Richert; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lambda K0s; Natural science; LHC; ALICE; Quark gluon plasma; 2.76 TeV; baryon-to-meson; Jet; Bulk; Lambda; K0s; Recombination; Coalescence; Fragmentation; Fysicumarkivet A:2016:Richert;

    Sammanfattning : In high energy heavy ion collisions, the QCD matter undergoes a phase transition to a hot and dense strongly coupled Quark Gluon Plasma, where quarks and gluons are deconfined in a volume of nuclear dimensions. At intermediate pT, 2 < p T < 8 GeV/c, a decoupling from pure hydrodynamical flow is observed, most noticeable in central collisions, demonstrated by the peak in the ratio of baryons to mesons, e.

  7. 15. The Axisymmetric Turbulent Jet

    Författare :Stephan Gamard; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis aims at understanding the downstream evolution of the most energetic features of a turbulent axisymmetric jet. The study was conducted from 2 to 69 diameters downstream, using 3 different jet exit diameters with air flowing at a wide range of velocities to ensure a reasonable span of Reynolds numbers, while still keeping it in a high range, from 40,000 to 156,700.
