Development of an Extensible Unified Control System Using the STARS Framework and Common Commands for Detector Control

Abstract

A zooming optical system comprising two Fresnel zone plates (FZPs) was developed and installed at the AR-NE1A beamline of the Photon Factory, High Energy Accelerator Research Organization (KEK), Japan. To ensure reliable and versatile operation, we implemented a dedicated control architecture based on the Simple Transmission and Retrieval System (STARS) framework and the newly proposed STARS Common Commands for Detector Control (CCDC)---a data-acquisition (DAQ) state model and command set designed specifically for detector control. The system serves both as a practical control system for the zooming optics and as a demonstration of modular extensibility using STARS and detector interoperability through CCDC. The system has been commissioned, and its performance has been verified at the AR-NE1A beamline. The architecture enables flexible configuration of optical components and provides a unified interface for both routine operation and advanced experimental protocols.
