  2. 1. Electron beam sizes and lifetimes at MAX II and MAX III

    Author : Anders Rosborg; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron accelerator; Storage ring; Synchrotron light source; Synchrotron radiation; Electron beam profile; Emittance; Beam size; Fysicumarkivet A:2012:Hansson; Lifetime; Bunch length; Landau cavities;

    Abstract : The MAX II and MAX III synchrotron light sources at MAX-lab provide synchrotron radiation for experiments in a wide variety of research fields. The synchrotron radiation is emitted by ultra-relativistic electrons circulating in electron storage rings. READ MORE

  4. 2. Diffractive Optical Elements: Fabrication, Replication, and Applications and Optical Properties of a Visual Field Test

    Author : Fredrik Nikolajeff; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perimetry; beam homogenizing; antireflection; high-pass spatial frequency target; proximity effect; electron beam lithography; replication; successive development; diffractive optical element; axicon;

    Abstract : This thesis mainly treats the fabrication, replication and applications of diffractive optical elements. A smaller part deals with optical properties of a visual field test. Diffractive optical elements are computer-generated micro-optic components that use diffraction to manipulate light. READ MORE

  5. 3. Investigation of Melt Pool Thermo-hydrodynamic Behaviour inLaser Beam Welding ofTi-6Al-4V through Numerical Simulation

    Author : Seyyed Mohammad Ali Noori Rahim Abadi; Isabelle Choquet; Fredrik Sikström; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser beam welding; Beam shaping; Absorptivity; Conductionmode welding; Free surface deformation; Computational Fluid Dynamics; OpenFOAM.; Strålformning; Absorptivitet; Värmeledningssvetsning; Ytdeformation; Computational Fluid Dynamics; OpenFOAM.; Production Technology; Produktionsteknik;

    Abstract : Laser is an efficient and widely used heat source in metal processing suchas welding and additive manufacturing. It has some great advantages compared to the other conventional heat sources like electron beam and arc namely: ability of handling complicated joint geometries and producing large components.

  6. 4. The modified Iosipescu shear test for orthotropic materials

    Author : Niklas Melin; Jonas Neumeister; Gradin Per; KTH; []
    Keywords : composite; modified Iosipescu tet; shear test; strain field uniformity; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : AbstractThe Iosipescu shear test, also known as asymmetric four point bending of a V-notched beam,is frequently used for measuring in-plane shear properties of composites. The ASTM standard(ASTM D-5379-05) regulates how the test is to be performed. READ MORE

  7. 5. The strength of glulam beams with holes - A probabilistic fracture mechanics method and experimental tests

    Author : Henrik Danielsson; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fracture mechanics; Weibull; design; test; strength; stress; glulam; hole; probabilistic fracture mechanics.;

    Abstract : This thesis deals with experimental tests and methods for strength analysis of glulam beams with holes. Test results and methods for strength analysis available in literature are compiled and discussed. The methods considered comprise both code strength design methods and more general methods for strength analysis. READ MORE
