A flexible start-to-end simulation framework for particle accelerators based on a comprehensive lattice description

Abstract

Standardization of data formats in a scientific discipline brings a range of benefits to researchers, as it enables the sharing of workflows and solutions to common problems, provides the foundation for generically useful tools that can be applied across the field, and gives a basis for cross-checking and validation that can be understood by all. Owing to the wide range of possible modes of description of particle accelerator lattices, a standard solution to this problem has not yet been developed for the field, although efforts are underway across the community. This article presents a schema for a comprehensive and generic format for describing particle accelerator lattices, encompassing physical element information, simulation code-specific parameters, control system variables, electrical and magnetic data, and other parameters, for each element. A translation layer is also provided in order to export this lattice into formats suitable for a variety of standard accelerator simulation codes. Based on this format, a framework has been developed for generating, tracking and analyzing beams through the lattice, providing a seamless transfer between simulation codes and the basis for a fully generic start-to-end simulation framework.
