2. 1. Plasma Synthesis and Self-Assembly of Magnetic Nanoparticles

   Author : Sebastian Ekeroth; Ulf Helmersson; Nils Brenning; Franz Faupel; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasma; Synthesis; Self-Assembly; Magnetic; Nanoparticles;

   Abstract : Nanomaterials are important tools for enabling technological progress as they can provide dramatically different properties as compared to the bulk counterparts. The field of nanoparticles is one of the most investigated within nanomaterials, thanks to the existing, relatively simple, means of manufacturing. READ MORE

4. 2. Intense laser-plasma interactions

   Author : Joel Magnusson; Chalmers tekniska högskola; []
   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.

5. 3. Plasma Interactions with Icy Bodies in the Solar System

   Author : Jesper Lindkvist; Mats Holmström; Martin Wieser; Elias Roussos; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; plasma interactions; icy bodies; solar system; space physics; plasma physics; hybrid model; numerical model; solar wind; magnetosphere; sub-Alfvénic; subsonic; non-collisional; atmosphereless; exosphere; coma; subsurface ocean; induction; magnetic dipole; pick-up ion; mass-loading; moon; natural satellite; dwarf planet; comet; Jupiter; Jovian; Callisto; Ceres; 67P; Churyumov-Gerasimenko; rymd- och plasmafysik; Space and Plasma Physics;

   Abstract : Here I study the “plasma interactions with icy bodies in the solar system”, that is, my quest to understand the fundamental processes that govern such interactions. By using numerical modelling combined with in situ observations, one can infer the internal structure of icy bodies and their plasma environments. READ MORE

6. 4. Advanced Plasma Analyzer for Measurements in the Magnetosphere of Jupiter

   Author : Joan Stude; Stas Barabash; Martin Wieser; Joseph H. Westlake; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; plasma instrumentation; time-of-flight; space; Jupiter; JUICE; PEP; JDC; start surface; charge fraction; the final frontier; accidental counts; chance counts; micro pore optics; spherical-wedge electrostatic analyzer; rymd- och plasmafysik; Space and Plasma Physics; fysik; Physics;

   Abstract : The Jupiter Icy Moons Explorer is a planetary exploration mission that aims to study the moons of Jupiter in the planet’s vast magnetosphere. Among the various instruments on board is the Particle Environment Package (PEP), that is led by the Swedish Institute of Space Physics (IRF) in Kiruna. READ MORE

7. 5. Low-energy ions around comet 67P/Churyumov-Gerasimenko

   Author : Sofia Bergman; Gabriella Stenberg Wieser; Martin Wieser; Gert Brodin; Stein Håland; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Low-energy ions; spacecraft charging; comets; 67P Churyumov-Gerasimenko; Rosetta; RPC-ICA; SPIS; diamagnetic cavity; field of view; plasma; space plasma physics; rymd- och plasmafysik; Space and Plasma Physics;

   Abstract : Low-energy ions play important roles in the formation of the plasma environment around a comet. Reliable ways of measuring these ions are therefore of high importance to fully understand the processes and dynamics of this environment. Unfortunately, low-energy ions are infamously difficult to detect. READ MORE
