Development and Application of the STARS‐based Beamline Control System at the Photon Factory

STARS[1–2] (Simple Transmission and Retrieval System) is a message transferring software for small‐scale control systems with TCP/IP sockets, originally developed at the Photon Factory (PF). Because it has a server‐client architecture using TCP/IP sockets and can work on various types of operating systems, the design and application are quite flexible. We have developed a common low‐level beamline control system based on the STARS technology. Many kinds of useful STARS clients (device drivers, data acquisitions, user interfaces etc.) are available now, and so far, the system has been installed at 22 PF beamlines. We will describe the development and generalize of the STARS‐based beamline control system at the PF.
