  1. 1. Neutron Spectroscopy Instrumentation and Methods for Fusion Plasmas

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Henrik Sjöstrand; Göran Ericsson; Johan Frenje; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neutron spectroscopy; plasma diagnostics; fusion power; fusion; plasma heating; MPRu; JET; triton burn-up; ITER; neutron yield; calibration; NATURAL SCIENCES Physics Geocosmophysics and plasma physics Fusion; NATURVETENSKAP Fysik Geokosmofysik och plasmafysik Fusion;

    Abstract : When the heavy hydrogen isotopes deuterium (D) and tritium (T) undergo nuclear fusion large amounts of energy are released. At the Joint European Torus (JET) research is performed on how to harvest this energy. Two of the most important fusion reactions, d+d→3He+n (En = 2.5 MeV) and d+t→4He+n (En = 14 MeV), produce neutrons. READ MORE

  2. 2. Infrared spectroscopy a tool for protein characterization

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Chenge Li; Andreas Barth; Silvia Maria Doglia; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Abstract : Infrared (IR) spectroscopy, which belongs to vibrational spectroscopy, detects the vibrations of molecules, for example, proteins. The absorption of the peptide group gives rise to 9 characteristic bands in the infrared region, named A, B, I-VII, with a decreasing energy or wavenumber (cm-1). READ MORE

    Abstract : Sensitive nonlinear acoustic methods are suitable for material characterization. This thesis describes three nonlinear acoustic methods that are proven useful for detection of defects like cracks and delaminations in solids. READ MORE

  4. 4. Aspects of Optical Broad Band Spectroscopy and Information Extraction - Applications in Medicine and Ecology

    University dissertation from Tryckeriet i E-huset, Lunds universitet

    Author : Mikkel Brydegaard; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fluorescence Spectroscopy; Optical diagnostics; Electro-optics; Applied spectroscopy; Multispectral imaging; Optical spectroscopy; LIDAR; Remote sensing; Environmental monitoring; Chemometrics; Fysicumarkivet A:2012:Brydegaard Sörensen;

    Abstract : The present thesis describes a number of aspects of modern electro-optical measurement technology also known as bio-photonics; this includes instrumentation, applications, sample interaction and data interpretation. The methods employed operate over several domains, and light measurements are discretized both in intensity, space, angle, time, polarization and energy. READ MORE
