  1. 1. Antiparticle identification studies for the PAMELA satellite experiment

    Författare :Jens Lund; Mark Pearce; Tuneyoshi Kamae; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Space technology; PAMEL; satellites; astroparticle physics; antiparticles; calorimeters; Rymdteknik; Space engineering; Rymdteknik;

    Sammanfattning : The PAMELA satellite experiment will soon be launched and during its 3 year mission perform measurement of charged particle fluxes in the cosmic radiation. PAMELA is specifically designed to identify antiprotons and positrons in the vast background of other charged particles. LÄS MER

  3. 2. Developments for the FPGA-Based Digitiser in the PANDA Electromagnetic Calorimeters

    Författare :Markus Preston; Per-Erik Tegnér; Samuel Silverstein; Pawel Marciniewski; Allan Hallgren; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; calorimeter; FPGA; single event upset; Geant4; Monte Carlo; pile-up; feature extraction; fysik; Physics;

    Sammanfattning : The strong interaction between quarks and gluons is one of the fundamental interactions described by the standard model of particle physics. Systems of quarks bound together by the strong interaction are known as hadrons, of which the proton and the neutron are the most common examples. LÄS MER

  4. 3. Calibration of the ATLAS calorimeters and discovery potential for massive top quark resonances at the LHC

    Författare :Elin Bergeås Kuutmann; Jörgen Sjölin; Kerstin Jon-And; Sten Hellman; Hans Bøggild; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; particle physics; the ATLAS experiment; the Large Hadron Collider; calorimeter; calorimetry; hadronic calibration; top quark; top quark pair resonances; search for physics beyond the Standard Model; Elementary particle physics; Elementarpartikelfysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : ATLAS is a multi-purpose detector which has recently started to take data at the LHC at CERN. This thesis describes the tests and calibrations of the central calorimeters of ATLAS and outlines a search for heavy top quark pair resonances. LÄS MER

  5. 4. Calorimetry under extreme conditions

    Författare :Neha Kondedan; Andreas Rydh; Ali Elshaari; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanocalorimetry; Diamond anvil cell; Specific heat; Thermometry; Quasicrystals; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : This licentiate thesis presents developments of nanocalorimetry systems tailored for use under extreme conditions such as high pressure, intense magnetic fields, and low temperature. Nanocalorimetry is a powerful approach to study strongly correlated systems like superconductors, heavy fermions, and quantum materials with non-trivial magnetic or electronic properties, materials with emergent magnetic orders, as well as quasicrystals.

  7. 5. ATLAS Calorimetry : Hadronic Calibration Studies

    Författare :Karl-Johan Grahn; Bengt Lund-Jensen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : The ATLAS experiment -- situated at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) in Geneva -- is on schedule to take its first collision data in 2009. Physics topics include finding the Higgs boson, heavy quark physics, and looking for extensions of the standard model such as supersymmetry. LÄS MER
