  SuperKEKB is the upgrade of KEKB, the asymmetric energy electron-positron collider for the B-factory experiment in Japan. It aims at the 40-times higher luminosity than the world record by KEKB. The KEKB control system has been built based on EPICS at the equipment layer and scripting languages at the operation layer. The SuperKEKB control system continues to employ these frameworks while we implement new features for the successful operation at such a high luminosity. As the commissioning of the SuperKEKB main storage rings is scheduled to start in 2016, the construction of the control system is now in the final phase. We have upgraded and reinforced the network system, server computers and operator consoles. Most of the VME-based IOCs (I/O Controllers), which has been widely used in KEKB, are upgraded while the PLC-based IOCs are also widely introduced. The new timing system has been developed in order to handle the complicated injection scheme of the SuperKEKB accelerator complex efficiently. The new beam abort trigger system and the new beam gate control system have been developed, and so on. The construction status of the SuperKEKB accelerator control system will be presented.

  There were more than 2500 magnet power supplies for KEKB storage rings and injection beam transport lines. For the remote control of such a large number of power supplies, the Power Supply Interface Controller Module (PSICM), which is plugged into each power supply, was developed. It has a microprocessor, ARCNET interface, trigger signal input interface, and parallel interface to the power supply. The PSICM is not only an interface card but also controls synchronous operation of the multiple power supplies with an arbitrary tracking curve. For SuperKEKB we have developed the upgraded version of the PSICM. It has the fully backward compatible interface to the power supply. The enhanced features includes high speed ARCNET communication and redundant trigger signals. Towards the phase 1 commissioning of SuperKEKB, the construction of the magnet control system is ongoing. First mass production of 1000 PSICMs has been completed and their installation is in progress. The construction status of the magnet control system is presented in this paper.
