OPAL-MITHRA: Self-consistent Software for Start-to-End Simulation of Undulator-based Facilities

Abstract

We present the recently started effort and progress towards the development of a software for start-to-end simulation of accelerator facilities employing undulator radiation. The core of this effort aims at the combination of two numerical solvers, the Object Oriented Parallel Accelerator Library (OPAL), a parallel open source tool for charged-particle optics in linear accelerators and rings, including 3D space charge, and the full-wave simulation tool for free electron lasers MITHRA, which solves the electromagnetic potential equations in free-space for radiating particles propagating along an undulator using an FDTD/PIC scheme. As an example, we present the application of the OPAL-MITHRA platform for the simulation of an experiment that will take place at the Argonne Wakefield Accelerator, in which the capability of a magnetic wiggler to induce energy modulation starting from a micro-bunched electron beam will be investigated.
