TED Develops FPGA Data Processing Boards for RIKEN's Next-Generation X-ray Image Detector 'CITIUS' for SPring-8
Tokyo Electron Device (TED) has co-developed FPGA-based data processing boards for 'CITIUS,' a next-gen detector for the SPring-8 synchrotron facility. These boards handle high-speed, high-reliability acquisition and processing of vast X-ray measurement data, contributing to an on-the-fly data compression of over 8,000 times.

Tokyo Electron Device Limited (Headquarters: Shibuya-ku, Tokyo; President & Representative Director: Takayoshi Miyamoto; hereinafter 'TED') has jointly developed with the National Research and Development Agency RIKEN (hereinafter 'RIKEN') FPGA-based data processing boards, the 'Proximity board' (hereinafter 'PRB') and the 'Data Framing Board' (hereinafter 'DFB'), as data processing boards for the next-generation X-ray image detector 'CITIUS,' which is being introduced at the large synchrotron radiation facility SPring-8. CITIUS is being developed as a new detector compatible not only with existing synchrotron radiation experiments but also with the increased brightness of future next-generation synchrotron radiation facilities like SPring-8-II, and TED's advanced board development and FPGA firmware development technology are responsible for its core data acquisition system.
TED has been delivering approximately 400 PRBs and 250 DFBs since fiscal year 2023, supporting the high-speed, high-reliability acquisition and processing of vast X-ray measurement data in the detector systems placed along the beamlines.
**Development Background**
SPring-8 is a large synchrotron radiation facility that utilizes the world's highest-brilliance synchrotron radiation and is used in a wide range of industrial and academic fields, including nanoscale structure analysis, physical property research, and materials development. With the planned increase in brightness from projects like SPring-8-II, the amount of data obtained per unit of time will further increase, requiring the following from detectors and data acquisition systems:
- On-the-spot compression of large amounts of data
- Real-time acquisition, storage, visualization, and analysis functions for wide-band, large-capacity data from high-brilliance beams
- Lower power consumption and more compact camera heads to accommodate experiments with extremely small beam sizes, such as nano-beams
- A compact and highly reliable hardware configuration that does not compromise operability at the experimental site
Particularly challenging was the technology to compress large amounts of data on the spot where it is detected. RIKEN recently reported achieving an on-the-fly compression of over 8,000 times for 19 PB of data per week as a system. TED contributed to achieving this high compression rate.

Based on its track record in server architecture design for high-bandwidth, low-latency, large-capacity, and compact systems, cultivated through FPGA-based high-speed data processing technology and image processing board development, TED has been jointly developing the detection and data acquisition system for CITIUS with RIKEN since 2016. TED is in charge of the core data processing boards of the system, the FPGA-based data processing boards (PRB and DFB), and is building an architecture that can respond to future functional expansions and changes in beam conditions through continuous development and evaluation, including FPGA firmware design know-how.
**About the 'PRB' and 'DFB' Data Processing Boards**
As the core data acquisition system of the CITIUS detector, TED has developed the FPGA-based 'PRB' and 'DFB' data processing boards (hereinafter collectively referred to as the data processing boards).
The main features of these data processing boards are as follows:
**Wide-Band, Large-Capacity Data Processing**
- Designed to continuously acquire, store, visualize, and analyze wide-band and large-capacity X-ray image data generated in high-brilliance synchrotron radiation experiments with high throughput.
- The FPGA-based design allows for flexible adaptation to future changes in beam conditions and measurement modes.
- By performing per-pixel background correction, noise removal thresholding, and integration of images acquired in rapid succession on the FPGA, it extracts scientifically meaningful data.
