  2. 1. Material migration in tokamaks : Erosion-deposition patterns and transport processes

    Author : Armin Weckmann; Marek Rubel; Rudolf Neu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEXTOR; fusion; plasma physics; transport; migration; tracers; tokamak; limiter; divertor; high-Z; ion beam analysis; Rutherford backscattering; Nuclear reaction analysis; Elastic recoil detection analysis; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Controlled thermonuclear fusion may become an attractive future electrical power source. The most promising of all fusion machine concepts is called a tokamak. The fuel, a plasma made of deuterium and tritium, must be confined to enable the fusion process. It is also necessary to protect the wall of tokamaks from erosion by the hot plasma. READ MORE

    Abstract : In this thesis, selected synthetic aspects of functional Metal-Organic Frameworks (MOFs) are considered. More specifically, the work is focused on MOFs doped with functional molecules in the role of structural linkers. READ MORE

  7. 5. Electron Energy Loss Spectroscopy of III-Nitride Semiconductors

    Author : Justinas Palisaitis; Per Persson; Lars Hultman; Jens Birch; Ernesto Coronel; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This Licentiate Thesis covers experimental and theoretical investigations of the bulk plasmon response to different compositions and strain states of group III-nitride materials. Investigated materials were grown using magnetron sputtering epitaxy and metal organic chemical vapour deposition and studied by Rutherford backscattering spectrometry, X-ray diffraction, electron microscopy and electron energy loss spectroscopy (EELS).
