Free-standing, axially-symmetric diffraction gratings for neutral matter-waves: experiments and fabrication
(The University of Bergen, 2011-10-04)
Since de Broglie’s famous postulation of the wave-nature of material particles and its subsequent experimental verification, it is known that atoms and molecules behave like waves on a small scale. The investigation of ...
Experimental and theoretical study of the flow, aggregation and deposition of gas hydrate particles
(The University of Bergen, 2010-06-21)
Gas hydrate plugging is considered to be a very problematic topic during petroleum production and transportation. The phenomenon of hydrate plug formation involves inter-related effects related to different disciplines, ...
Performance of the High Level Trigger gamma-conversion reconstruction chain in the ALICE central tracking detectors
(The University of Bergen, 2011-06-01)
Photons are produced through various processes in the particle and nuclei collisions at the LHC, and pose as useful probes of the formation of a Qaurk-Gluon Plasma. The probability of a photon converting within the central ...
Recreating the top quark: Commissioning and monitoring of the ATLAS Inner Detector and search for New Physics with heavy particles.
(The University of Bergen, 2012-02-03)
The ATLAS (A Toroidal Lhc ApparatuS) experiment is one of the two general purpose experiments at the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research. The LHC is a proton-proton and ...
Measurements of the Photonuclear Neutron Yield During Radiotherapy Using Bubble Detectors and Thermoluminescence Detectors
(The University of Bergen, 2010-02-22)
Medical linear accelerators (linacs) used for radiotherapy with photons produce an undesirable neutron contribution as treatment energies exceed the (γ,n) threshold of the high-Z constituents of the linac. Secondary ...
Hydrodynamical studies of Quark Gluon Plasma: Collective behaviour, initial fluctuations and theoretical fundaments
(The University of Bergen, 2012-05-30)
This master thesis focuses on collective behaviour of the Quark Gluon Plasma, created at the Large Hadron Collider at CERN. We calculate analytically and semi-analytically the transverse momentum and rapidity dependence ...
Reciprocity calibration method for ultrasonic piezoelectric transducers in air
(The University of Bergen, 2013-06-17)
The conventional three-transducer reciprocity calibration method for use in gas at ambient pressure and temperature is studied. Modifications are introduced, introducing correction factors for absorption in air, diffraction ...
Two particle correlation effects from rotation and instabilities in heavy ion collisions
(The University of Bergen, 2013-05-18)
Two particle correlations are studied in the reaction plane of peripheral relativistic heavy ion reactions where the initial state has substantial angular momentum. The earlier predicted rotation effect and Kelvin Helmholtz ...
Bridge over Troubled Water - veien fra akademia til industri - og tilbake
(The Michelsen Centre or Industrial Measurement Science and Technology, 2010-04-15)
