  1. 1. Nonlinear Beam Physics

    University dissertation from Lund University , Department of physics

    Author : Benjamin Folsom; Lund University.; Lunds universitet.; [2019-03-30]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nonlinear dynamics; Beam dynamics; Accelerator Physics; space charge; Accelerator magnets; simulations multi-particle dynamics;

    Abstract : A condensed treatment of conventional beam physics (both linear and nonlinear) is given for the non-expert; this constitutes a minimum knowhow for constructing simulations of rudimentary beamlines. The criteria for an ideal nonlinear charged-particle simulation algorithm are then presented, leading to the derivation of a symplectic, explicit, Lorentz-covariant integrator. READ MORE

  5. 5. Development of Techniques for 3D Imaging with Focused Ion Beams - Hydrogen Depth Profiling and Microtomography with Applications in Geology

    University dissertation from Division of Nuclear Physics Department of Physics Lund University Box 118 SE-221 00 Lund Sweden

    Author : Marie Wegdén; Lund University.; Lunds universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrogen analysis; Depth profiling; Ion beam analysis; Nuclear microprobe; Physics; Nuclear physics; Fysik; Fysicumarkivet A:2007:Wegdén; Kärnfysik; Tomography; 3D Imaging;

    Abstract : In nuclear microprobe experiments, high resolution maps of the measured parameter, e.g. element- or mass distribution, in a sample can be produced with a variety of ion beam analytical techniques. The principle underlying all the techniques is that ions at MeV energies are used as projectiles to cause interactions with the target material. READ MORE
