Atomic Spectroscopy on Fusion Relevant Ions and Studies of Light Impurities in the JET Tokamak

Popular Abstract in Swedish Kontroll av fororeningar i dagens fusionsmaskiner aer ett inte alltfor stort problem. De kan dock anvandas for diagnostiskt syfte eftersom deras linjeemission avslojar ett flertal intressanta plasmaparametrar. For att kunna maeta egenskaper som jontemperatur, jondensitet och plasmarotation i ett fusionsplasma, aer det av yttersta vikt att den spektroskopiska tolkningen The spectrum and energy levels C IV and the 3l4l' system of the Mg-like ions in the iron group elements has been investigated. This has led to several hundred identified transitions, many of them previously unknown. Using the Charge Exchange diagnostic system at JET, ion temperatures, rotation velocities and densities have been derived from visible spectroscopic measurements on fully ionised light

Grammaticalization of prosody in the brain

Based on the results from three Event-Related Potential (ERP) studies, we show how the degree of grammaticalization of prosodic features influences their impact on syntactic and morphological processing. Thus, results indicate that only lexicalized word accents influence morphological processing. Furthermore, it is shown how an assumed semi-grammaticalized left-edge boundary tone activates main cl

A Dipole Model for High Energy QCD

Popular Abstract in English This thesis considers a model of high energy particle collisions. The model is based on the so called BFKL formalism which is valid only at low x, that is collisions at very high energies, such as at the LHC. The intial state of the incoming particles are simulated by colour dipoles in transverse space evolved through rapidity. With this approach, all fluctuations are dThis thesis considers a model of high energy particle collisions. The model is based on the so called BFKL formalism which is valid only at low x, that is collisions at very high energies, such as at the LHC.
