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.

The screen monitor (SC) of the KEK linac is a beam diagnostics device to measure transverse beam profiles with a fluorescent screen. The screen material is made of 99.5% Al2O3 and 0.5% CrO3, with which a sufficient amount of fluorescent light can be obtained when electron and positron beams impinge on the screen. the fluorescent light with a camera embedded with a charge-coupled device (CCD), the transverse spatial profiles of the beam can be easily measured. Compact SCs were previously developed in 1995 for the KEKB project. About 110 compact SCs were installed into the beam line at that time. VME-based computer control system was also developed in order to perform fast and stable control of the SC system. However, the previous system becomes obsolete and hard to maintain. Recently, a new screen monitor control system for the KEK electron/positron injector linac has been developed and fully installed. The new system is an embedded EPICS IOC based on the Linux/PLC. In this paper, we present the new screen monitor control system in detail.
