2. 1. Modeling of Electron Cooling : Theory, Data and Applications

   Author : Karin Rathsman; Tord Johansson; Pia Thörngren; Dieter Prasuhn; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron cooling; Beam dynamics; Vlasov technique; Nonlinear damping; Monte Carlo simulations; Nuclear physics; Kärnfysik; Nuclear Physics; Kärnfysik;

   Abstract : The Vlasov technique is used to model the electron cooling force. Limitations of the applicability of the method is obtained by considering the perturbations of the electron plasma. READ MORE

4. 2. Numerical Vlasov–Maxwell Modelling of Space Plasma

   Author : Bengt Eliasson; Bertil Gustafsson; Bo Thidé; Anders Bondeson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Vlasov equation; Maxwell equation; Fourier method; outflow boundary; domain decomposition; Numerical Analysis; Numerisk analys;

   Abstract : The Vlasov equation describes the evolution of the distribution function of particles in phase space (x,v), where the particles interact with long-range forces, but where shortrange "collisional" forces are neglected. A space plasma consists of low-mass electrically charged particles, and therefore the most important long-range forces acting in the plasma are the Lorentz forces created by electromagnetic fields.

5. 3. Numerical simulation of kinetic effects in ionospheric plasma

   Author : Bengt Eliasson; Bertil Gustafsson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

   Abstract : In this thesis, we study numerically the one-dimensional Vlasov equation for a plasma consisting of electrons and infinitely heavy ions. This partial differential equation describes the evolution of the distribution function of particles in the two-dimensional phase space (x,v). READ MORE
