  1. 1. Modeling of radiative processes in organic scintillators

    Author : Jenny Nilsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents the development of a Monte Carlo calibration of a whole body counter (WBC), consisting of four large plastic (organic) scintillators, used for determine the body burden of gamma-emitting radionuclides. A scintillator emits optical photons after energy has been deposited by an ionizing particle in the scintillator material. READ MORE

  2. 2. Fibre Bragg Gratings : Characterization, Realization and Simulation

    Author : Ingemar Petermann; Ari Friberg; Sten Helmfrid; Morten Ibsen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bragg gratings; optical fibres; optical fibre components; Physics; Fysik;

    Abstract : The main topic of this thesis is realization and characterization of fibre Bragg gratings. A novel versatile grating fabrication technique is developed and a number of gratings are realized, showing the potential of the system. READ MORE

  3. 3. Modelling late toxicity in hypofractionated radiation therapy

    Author : Niclas Pettersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hypofractionation; normal tissue complication probability; modelling; linear-quadratic model; fractionation sensitivity; late toxicity; radiation-induced rib fracture; genitourinary toxicity; stereotactic body radiation therapy; high-dose-rate brachytherapy; multimodality radiation therapy; patient-reported outcomes; prostate cancer; nsclc;

    Abstract : In hypofractionated radiation therapy (RT), the treatment is delivered by few fractions with high doses per fraction. This is in contrast to conventionally fractionated RT where the total dose is delivered in many fractions with low doses per fraction. READ MORE

  4. 4. ATLAS Calorimetry : Hadronic Calibration Studies

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

    Abstract : 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. READ MORE

  5. 5. Density Functionals for Dynamic Linear Response in Finite Systems

    Author : Maria Hellgren; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This dissertation investigates a new method for obtaining excited-state properties of finite, many-electron systems such as atoms, molecules and nano-systems. The method combines the merits of many-body perturbation theory and time-dependent perturbation theory and yields approximate density response functions which preserve basic physical conservation laws.
