	We will start a full energy injection from the SACLA to the SPring-8 from next year as a part of the SPring-8 upgrade. For this, we developed several I/O cards with the MTCA.4 form factor. One of the key issues is a timing synchronization between SACLA and SPring-8. We implemented required functions on the FPGA logic of a commercially available I/O card. We develop a module to distribute a trigger and clocks. We also developed cards used for the beam position monitor (BPM) and low-level RF system (LLRF). Those are included two types of cards. One is a 16-bit digitizer used for LLRF for the SPring-8 since 2018 march. We will use the card for the BPM with modified FPGA logic. Second is an implementation of functions with the pulsed RF signals processed on the FPGA logic of a commercially available card. These functions are used for the BPM of the beam transport line from the SACLA to SPring-8. The existing system is used 1 Hz beam repetition but we need more than 10 Hz to achieve an injection time less than 20 minutes to maximize user time. We will report the performance of the MTCA.4 cards, the upgrade plan of the SPring-8, and the construction of the 3 GeV Light Source.

WECPL01	Status of the Control System for Fully Integrated SACLA/SPring-8 Accelerator Complex and New 3 GeV Light Source Being Constructed at Tohoku, Japan	904

	In the SPring-8 upgrade project, we plan to use the linear accelerator of SACLA as a full-energy injector to the storage ring. For the purpose of simultaneous operation of XFEL lasing and on-demand injection, we developed a new control framework that inherits the concepts of MADOCA. We plan to use the same control framework for a 3 GeV light source under construction at Tohoku, Japan. Messaging of the new control system is based on the MQTT protocol, which enables slow control and data acquisition with sub-second response time. The data acquisition framework, named MDAQ, covers both periodic polling and event-synchronizing data. To ensure scalability, we applied a key-value storage scheme, Apache Cassandra, to the logging database of the MDAQ. We also developed a new parameter database scheme, that handles operational parameter sets for XFEL lasing and on-demand top-up injection. These parameter sets are combined into 60 Hz operation patterns. For the top-up injection, we can select the operational pattern every second on an on-demand basis. In this paper, we report an overview of the new control system and the preliminary results of the integrated operation of SACLA and SPring-8.

WEPHA068	A Control System Using EtherCAT Technology for The Next-Generation Accelerator	1258

	The construction of a new 3 GeV Light Source is in progress. The 3 GeV Light Source will be designed a compact and stable Linac based on the C-band accelerator developed by SACLA. Furthermore, we have an upgrade project of SPring-8 that we call SPring-8-II. We adopted EtherCAT technology as a network fieldbus for the next-generation control system. Currently, as the control systems using EtherCAT, a low-level RF system and a new standard in-vacuum undulator system are running at the SPring-8 storage ring. Additionally, it is necessary to upgrade a high-power RF (HPRF) system at SACLA and a magnet power supply system. The current HPRF system consists of a VME and four PLCs. These PLCs are connected by an optical FA-Link that had been discontinued. Therefore, we will construct a new HPRF system that is replaced a VME with MTCA.4 and is used EtherCAT as a fieldbus. A fieldbus of a magnet power supply system will be replaced an old optical link with EtherCAT. The new systems will be verified into a prototype accelerator for the 3 GeV Light Source in SPring-8 site. The control systems using EtherCAT will be installed into the 3 GeV Light Source and SPring-8-II.

We will upgrade the beam monitor system for beam transport, which consists of screen monitor (SCM), beam position monitor (BPM) and current monitor (CT). For the SCM, we adopted GigE Vision standard for the CCD camera and EtherCAT as a field bus for the stepper motor control of focusing system. We have developed camera control software using open source libraries to integrate various vendors’ GigE Vision cameras with the SPring-8 control framework. A grabbed image is stored into the file server and property, such as camera settings for image and event number, is stored into the database. The BPM is a key device for precise and stable injection. We adopted the commercially available MTCA.4 fast ADC/DAC module with modified firmware developed for readout of the BPM and the CT. We are developing acquisition software for MTCA.4 modules to synchronize with a beam trigger. The acquired data are stored into the database with time stamp and event number. We present the preparation of beam monitor control system for the beam transport to injection from SACLA to SPring-8.
