Third-order charged particle beam optics
The motion of a charged particle through a magnetic field configuration can be described in terms of deviation from a certain ideal trajectory. One uses power series expansion of the phase-space coordinates to obtain the transfer matrices for a particular optical system. In this thesis we present a …

Interaction of charged particle beams with plasmas
This thesis focuses on the propagation of charged particle beams in plasmas, and is divided into two main parts. In the second chapter, a novel theoretical model for underdense electron beam propagation during the nonlinear stage of the resistive Weibel instability (WI) is presented and is used to …

Analysis of moment-preserving methods for charged particle transport
The simulation of electrons, protons, and other charged particles can be an expensive computation. On the one hand, the small mean free path of a charged particle makes direct simulations very costly. On the other hand, the cross sections are very singular making a deterministic calculation …

Massive stable charged particle signatures in simulations at the LHC
The importance of heavy stable charged (HSCP) particles lies in the exploration of extensions to the standard model. Extensions of the standard model attempt to solve current problems in the standard model such as the Hierarchy Problem. The Hierarchy Problem centers on the lack of an explanation in …
