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

   Author : Henrik Sjöstrand; Göran Ericsson; Johan Frenje; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neutron spectroscopy; plasma diagnostics; fusion power; fusion; plasma heating; MPRu; JET; triton burn-up; ITER; neutron yield; calibration; Fusion; 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

4. 2. Infrared spectroscopy : a tool for protein characterization

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

   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

5. 3. Nonlinear Acoustics Applied to NonDestructive Testing

   Author : Kristian Haller; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear acoustics; nondestructive testing; activation density; slow dynamics; resonance frequency; nonlinear wave modulation spectroscopy; harmonic generation; trapped modes; open resonator; sweep rate;

   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

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

   Author : Mikkel Brydegaard; Atomfysik; []
   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

   Abstract : Abstract In this thesis, the high temperature superconductors (HTSC) La2CuO4+x and Bi2Sr2CaCu2O8+d and the colossal magnetoresistive (CMR) La1-xSrxMnO3 have been studied by photoelectron spectroscopy. Techniques such as angular resolved photoemission (ARPES), resonant photoemission spectroscopy (RESPES) and x-ray absorption spectroscopy have been applied, using synchrotron radiation. READ MORE
