  2. 1. Approaches to particle acceleration in intense laser-matter interaction

    Author : Joel Magnusson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; particle-in-cell; nonlinear dynamics; laser; plasma; laser-matter interaction; particle acceleration;

    Abstract : In the interaction of ultra-intense laser fields with matter, the target is rapidly ionized and a plasma is formed. The ability of a plasma to sustain acceleration gradients, orders of magnitude larger than achievable with conventional accelerators, has led to a great interest in laser-driven plasma-based particle acceleration and radiation generation, with applications in materials science, biology and medicine.

  4. 2. Radiation in simulations of high intensity laser-matter interaction

    Author : Erik Karl Wallstén Wallin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plasma; nonlinear dynamics; particle-in-cell; Manley-Rowe; radiation reaction; synchrotron radiation;

    Abstract : We consider electromagnetic waves propagating in plasmas, with two main themes covered. First nonlinear plasma theory and wave-wave interaction. Here a wave-wave symmetry, the Manley-Rowe relations, is used as a method of determining the physicality of modified plasma fluid equations. READ MORE

  5. 3. Coil Design and Related Studies for the Fusion-Fission Reactor Concept SFLM Hybrid

    Author : Anders Hagnestål; Olov Ågren; Vladimir Moiseenko; Ladislav Bardos; Jan Scheffel; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fusion; Fission; Hybrid reactor; Actinides; Mirror Machine; Quadrupolar mirror; Coils; Fysik; Physics;

    Abstract : A fusion-fission (hybrid) reactor is a combination of a fusion device and a subcritical fission reactor, where the fusion device acts as a neutron source and the power is mainly produced in the fission core. Hybrid reactors may be suitable for transmutation of transuranic isotopes in the spent nuclear fuel, due to the safety margin on criticality imposed by the subcritical fission core. READ MORE

  6. 4. Pushing methods for plasma simulations into the QED regime

    Author : Erik Karl Wallstén Wallin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LWFA; nonlinear dynamics; plasma; Manley-Rowe; particle-in-cell; synchrotron radiation; radiation reaction;

    Abstract : The interaction between a super-intense laser pulse, with intensity up to 10²² W/cm², and a plasma opens new regimes of physics, with new questions and more demand on existing numerical tools. Relativistic and quantum effects which are negligible for lower laser intensities become important and must be properly modelled to generate reliable predictions. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; radiation reaction; radiation generation; particle-in-cell; plasma; pair production cascades; ion acceleration; laser;

    Abstract : In the interaction of ultra-intense laser fields with matter, the target is rapidly ionized and a plasma is formed. The ability of a plasma to sustain acceleration gradients, orders of magnitude larger than achievable with conventional accelerators, has led to a great interest in laser-driven plasma-based particle and radiation sources, with applications in materials science, biology and medicine.
