Treatment planning optimization strategies for the relative biological effectiveness and oxygen enhancement ratio in proton therapy
(Doctoral thesis, 2022-09-23)Sidan kreftbehandling med proton gir ein høgare biologisk effekt enn foton, blir ein relativ biologisk effekt (RBE) brukt for å ta omsyn til forskjellen. I klinisk protonterapi i dag blir ein konstant RBE på 1.1 nytta, ... -

Triboelectric proximity and contact detection using soft planar spiral electrodes
(Peer reviewed; Journal article, 2019-08-02)In this study, planar spiral electrodes for triboelectric contact and proximity detection are investigated. The spiral electrodes are created using liquid metal in a soft elastomer in order to make the sensor flexible and ... -
A trigger readout system for the Forward Calorimeter(FoCal)
(Master thesis, 2012-11-20)The University of Bergen, Norway is currently involved in the development and building of the Forward Calorimeter (FoCal) as an upgrade to the ALICE (A Large Ion Collider Experiment) detector at CERN (European Organization ... -
Trilinear-augmented gaugino mediation
(Peer reviewed; Journal article, 2017-05-02)We consider a gaugino-mediated supersymmetry breaking scenario where in addition to the gauginos the Higgs fields couple directly to the field that breaks supersymmetry. This yields non-vanishing trilinear scalar couplings ... -
The true fluence distribution of terrestrial gamma flashes at satellite altitude

True-to-size surface mapping with neutral helium atoms
(Journal article; Peer reviewed, 2021)Three-dimensional mapping of microscopic surface structures is important in many applications of technology and research, including areas as diverse as microfluidics, MEMS, and geoscience. However, on the nanoscale, using ... -
Tuning the electronic band structure of metal surfaces for enhancing high-order harmonic generation
(Journal article; Peer reviewed, 2021)High-harmonic generation (HHG) from the condensed matter phase holds promise to promote future cutting-edge research in the emerging field of attosecond nanoscopy. The key for the progress of the field relies on the ... -
Turbulence, Vorticity and Lambda Polarization
(Journal article; Peer reviewed, 2014)Present highest energy heavy ion experiments show the dominance of the fluid dynamical processes. The possibility of new collective phenomena, rotation and turbulence occurs, which were known only in macroscopic systems ... -
Two dark matter candidates in three-Higgs-doublet models with S3 symmetry
(Journal article; Peer reviewed, 2022)Models with an extended scalar electroweak sector can have vanishing vacuum expectation values in a basis where an underlying symmetry is imposed. Such extensions are very well motivated. If a symmetry prevents couplings ... -
Two Higgs Doublets plus One Dark Matter Singlet
(Master thesis, 2010-08-01)In this thesis an extension of the 2HDM (see chapter 1) is explored. The extension admits an extra inert singlet which is a dark matter candidate. Before the exploration a large part of the thesis (chapter 2) is an overview ... -
Two mechanisms of stratospheric ozone loss in the Northern Hemisphere, studied using data assimilation of Odin/SMR atmospheric observations
(Peer reviewed; Journal article, 2017-02-07)Observations from the Odin/Sub-Millimetre Radiometer (SMR) instrument have been assimilated into the DIAMOND model (Dynamic Isentropic Assimilation Model for OdiN Data), in order to estimate the chemical ozone (O3) loss ... -
Two particle correlation effects from rotation and instabilities in heavy ion collisions
(Master thesis, 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 ... -
Two- and three-pion quantum statistics correlations in Pb-Pb collisions at √sNN = 2.76 TeV at the CERN Large Hadron Collider
(Peer reviewed; Journal article, 2014-02-26)Correlations induced by quantum statistics are sensitive to the spatiotemporal extent as well as dynamics of particle-emitting sources in heavy-ion collisions. In addition, such correlations can be used to search for the ... -
Two-particle azimuthal correlations in photonuclear ultraperipheral Pb+Pb collisions at 5.02 TeV with ATLAS
