A Time-adaptive Mesh Approach for the Self-consistent Simulation of Particle Beams
نویسندگان
چکیده
The high spatial resolution needed in self-consistent particle simulations can be achieved using adaptive mesh refinement techniques (AMR). In this paper the code SMOVE which is based on such an adaptive mesh is presented. It allows for accurate simulations with a high spatial resolution in the vicinity of the particle bunches. Furthermore, it offers the possibility of simulating long accelerator structures of several meters length. The code is tested and validated using the RF electron gun of the Photo Injector Test Facility at DESY Zeuthen (PITZ) as an example. The evolution of various beam parameters along the gun is compared with the results obtained by different beam dynamics codes.

Development of a Self-consistent Particle-in-cell (pic) Code Using a Time-adaptive Mesh Technique∗
For a large class of problems the self-consistent simulation of charged particle beams in linear accelerators is necessary. Typically, Particle-In-Cell (PIC) simulations use a fixed computational grid which has to resolve the bunch adequately. This leads to enormous memory consumption. Therefore, and especially in the 3D case, only rather short sections can be simulated. A remedy to this limita...

In this paper a novel hybrid algorithm for harmonics estimation in power systems is proposed. The estimation of the harmonic components is a nonlinear problem due to the nonlinearity of phase of sinusoids in distorted waveforms. Most researchers implemented nonlinear methods to extract the harmonic parameters. However, nonlinear methods for amplitude estimation increase time of convergence. Hen...
