  2. 16. The Statistics of Emission and Detection of Neutrons and Photons

    Author : Andreas Enqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiplicities; nuclear safeguards; Number distribution; scintillation detectors; light pulse distribution; fissile material; cross correlations;

    Abstract : One particular purpose of nuclear safeguards, in addition toaccounting for known materials, is the detection, identifying and quantifying unknown material, to prevent accidental and clandestine transports and uses of nuclear materials. This can be achieved in a non-destructive way through the various physical and statistical properties of particle emission and detection from such materials. READ MORE

  4. 17. Study of Two-Photon processes at low Q2 using the VSAT calorimeter in the DELPHI experiment

    Author : Pavel Tyapkin; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; högenergi; QCD; STIC; VSAT; DELPHI; LEP; antitag; double tag; single tag; photon structure function; hadronic cross-section; virtual photons; two-photon; gamma-gamma; Kosmisk strålning; cosmic rays; High energy interactions; PHOJET; TWOGAM; PYTHIA; VDM; GSP; Fysicumarkivet A:2004:Tyapkin;

    Abstract : The study is based on data collected at the LEP II accelerator during the second period of the Large Electron-Positron collider operations (1996-2000). During that time the DELPHI (DEtector with Lepton, Photon and Hadron Identification) experiment collected about 90 Gb of data on tape corresponding to 687-691 pb-1 of luminosity. READ MORE

  5. 18. Two-body Photodisintegration of ³He

    Author : Martin Karlsson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; differential cross sections; three-nucleon forces; MAX-lab; tagged photons; Nuclear physics; Kärnfysik; Fysicumarkivet A:000;

    Abstract : In a series of experiments using the tagged photon facility at MAX-lab located in Lund, Sweden, the two-body photodisintegration of ³He has been investigated in the photon energy range 14--32 MeV. Differential cross sections of the reaction ³He(g,d) have been measured by detecting deuterons and protons in silicon surface barrier detectors. READ MORE

  7. 20. Quantum optics in superconducting circuits : Generating, engineering and detecting microwave photons

    Author : Sankar Raman Sathyamoorthy; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; single photon source; superconducting circuits; single photon detector; cross-Kerr effect; Quantum optics; circuit QED;

    Abstract : Quantum optics in superconducting circuits, known as circuit QED, studies the interaction of photons at microwave frequencies with artificial atoms made of Josephson junctions. Although quite young, remarkable progress has been made in this field over the past decade, especially given the interest in building a quantum computer using superconducting circuits. READ MORE
