  New imaging stations with high-resolution pixel detectors and other synchrotron instrumentation have ever increasing sampling rates and put strong demands on the complete signal processing chain. Key to successful systems is high-throughput computing platform consisting of DAQ electronics, PC hardware components, communication layer and system and data processing software components. Based on our experience building a high-throughput platform for real-time control of X-ray imaging experiments, we have designed a generalized architecture enabling rapid deployment of data acquisition system. We have evaluated various technologies and come up with solution which can be easily scaled up to several gigabytes-per-second of aggregated bandwidth while utilizing reasonably priced mass-market products. The core components of our system are an FPGA platform for ultra-fast data acquisition, Infiniband interconnects and GPU computing units. The presentation will give an overview on the hardware, interconnects, and the system level software serving as foundation for this high-throughput DAQ platform. This infrastructure is already successfully used at KIT's synchrotron ANKA.

  STARS is a message transferring software for small-scale control systems originally developed at the Photon Factory. It has a server-client architecture using TCP/IP sockets and can work on various types of operating systems. Since the Photon Factory adopted STARS as a common beamline control software, we have developed beamline control system which controls optical devices (mirror, monochrometer etc.). We developed also various system and softwares, such as information delivering system of Photon Factory ring status based on STARS and TINE or measurement softwares based on the STARS, for the Photon Factory beamlines. Now many kinds of useful STARS applications (device clients, simple data acquisitions, user interfaces etc.) are available. We will describe the development and installation status of the STARS-based beamline system and softwares.

  The establishment of data model is more abundant based on OPC UA (Unified Architecture) technology, which has good platform independence and high reliability. Thus it becomes a new direction in the field of data exchange of industrial control. In this paper, the motion control model based on redundant ring network is built by using NI 3110 industrial controller and servo motors. And the data structures used in parallel communication between the host computer and multi terminal motors are designed by using OPC UA technology. So the problem of data exchange between the RT system of lower controller and the Windows system of upper computer is solved better.

  To study the synchrotron terahertz emission superconducting (YBCO) film detectors are used with the intrinsic response time in the order of a few picoseconds. For fast, continuous sampling of the individual THz ultra-short pulses a novel digitizer system has been developed. The system consists of detector, wideband low-noise amplifier, fast pulse digitizer board, back-end readout board. High-end graphic processing units (GPUs) perform real-time data analysis. Four samples with 12 bit are recorded in parallel for each fast pulse with programmable sampling times in the range of 3 to 100 ps. A new bus master DMA engine connected to PCI express endpoint has been developed to ensure a continuous high data throughput of up to 4 GByte/s. This heterogeneous real-time system architecture based on FPGA and GPU has successful been used for on-line pulse reconstruction and evaluations and calculates the peak amplitude of each pulse and the time between consecutive bunches with a picosecond time resolution at ANKA. A Fast Fourier Transform (FFT) is performed on-line for the frequency analysis of the CSR undulations.
