Description
Modern software systems increasingly require modular, reusable components that scales across diverse application domains. In accelerator physics, machines often rely on specialized simulation codes tailored to distinct segments of the accelerator, making integrated start-to-end studies complex and fragmented. Here, we introduce GEIST (Genesis–Elegant Interface Simulation Toolset), an interdisciplinary library designed for linear accelerator-based free-electron laser (FEL) simulations, with particular emphasis on seeded FEL schemes. GEIST provides a unified framework for coupling established simulation tools, enabling consistent data exchange and streamlined workflows across otherwise incompatible codes.
To support this flexibility, we present PHYSYNC, a decoupled library that has evolved from within GEIST into a standalone, general-purpose solution. PHYSYNC enables consistent transformation and mapping of physical parameters — such as momentum, energy, and spatial coordinates — across different simulation environments. Its design supports large-scale distributions with one-to-one correspondence between particles and distribution elements, making it applicable not only within GEIST but also across a broader range of simulation workflows and external libraries. Together, GEIST and PHYSYNC exemplify how domain-specific software can evolve into modular ecosystems, improving reusability while supporting sustainability-conscious studies in accelerator modeling.
