SuperKEKB is the upgrade of the KEKB asymmetric energy e⁺e⁻ collider, for the B-factory experiment in Japan, designed to achieve a 40-times higher luminosity than the world record by KEKB. The KEKB control system was based on EPICS at the equipment layer and scripting languages at the operation layer. The SuperKEKB control system continues to employ those features, while we implement additional technologies for the successful operation at such a high luminosity. In the accelerator control network system, we introduce 10GbE for the wider bandwidth data transfer, and redundant configurations for reliability. The network security is also enhanced. For the SuperKEKB construction, the wireless network is installed into the beamline tunnel. In the timing system, the new configuration for positron beams is required. We have developed the faster response beam abort system, interface modules to control thousands magnet power supplies, and the monitoring system for the final focusing superconducting magnets to assure stable operations. We introduce the EPICS embedded PLC, where EPICS runs on a CPU module. The design and status of the SuperKEKB accelerator control system will be presented.

SuperKEKB is the upgrade of the KEKB asymmetric energy electron-positron collider, for the next generation B-factory experiment in Japan. It is designed to achieve a luminosity of 8x10³⁵/cm²/s, 40 times higher than the world highest luminosity record at KEKB. For SuperKEKB, we upgrade the accelerator control network system, which connects all devices in the accelerator. To construct the higher performance network system, we install the network switches based on the 10 gigabit Ethernet (10GbE) for the wider bandwidth data transfer. Additional optical fibers, for the reliable and redundant network and for the robust accelerator control timing system, are also installed. For the KEKB beamline construction and accelerator components maintenance, we install the new wireless network system based on the Leaky Coaxial (LCX) cable antennas into the 3 km circumference beamline tunnel. We reconfigure the network design to enhance the reliability and security of the network. In this paper, the design and current status of the SuperKEKB accelerator control network system will be presented.
