  For reliable accelerator operation, it is essential to have a centralized data handling scheme, for such as unique equipment ID's, archive and online data from sensors, and operation points and calibration parameters those are to be restored upon a change in operation mode. Since 1996, when SPring-8 got in operation, a database system has been utilized for this role. However, as time passes the original design got shorthanded and new features equipped upon requests pushed up maintenance costs. For example, as SACLA started in 2010, we introduced a new data format for the shot by shot synchronized data. Also number of tables storing operation points and calibrations increased with various formats. Facing onto the upgrade project at the site*, it is the time to overhaul the whole scheme. In the plan, SACLA will be the high quality injector to a new storage ring while in operation as the XFEL user machine. To handle shot by shot multiple operation patterns, we plan to introduce a new scheme where multiple tables inherits a common parent table information. In this paper, we report the database design for the upgrade project and status of transition.

  At the SPring-8 site, the X-ray free electron laser facility, SACLA, and the third generation light source, SPring-8 storage ring, is operated. The SACLA generate brilliant coherent X-ray beams with wavelength of below 0.1nm and the SPring-8 provides brilliant X-ray to large number of experimental users. On the SPring-8 upgrade project we have a plan to use the linac of SACLA for a full-energy injector. For this purpose, two accelerators should be controlled seamlessly and the SACLA has to operate as to generate X-ray laser and injector for the SPring-8 simultaneously. We start the design of control system to meet those requirements. We redesign all of a control framework such as Database, Messaging System and Equipment Control include with NoSQL database, MQTT and EtherCAT. In this paper, we will report the design of control system for SACLA/SPring-8 together with status of the SPring-8 upgrade project.
