“…The xTCA (MTCA and ATCA) specifications, developed by PCI Industrial Computer Manufacturers Group (PICMG) for telecommunication applications, have been rapidly evolving recently and therefore are attractive solutions for a demanding data acquisition and control systems [18], [19]. Both standards support transfers with throughputs up to 40 Gbps (twice as much is available for dual star configuration).…”

Fast evolution of high-performance cameras in recent years has made them promising tools for observing transient and fast events in large-scale scientific experiments. Complex experiments, such as ITER, take advantage of high-performance imaging system consisting of several fast cameras working in the range of visible and infrared light. However, the application of such devices requires a usage of high-performance data acquisition systems able to read and transfer large amount of data, reaching even 10 Gbit/s for a single camera. The MTCA.4 form factor fulfils the requirements of demanding imaging systems. The paper presents a first implementation of a complete image acquisition system built on the basis of MTCA.4 architecture, which is dedicated for the operation with high-resolution fast cameras equipped with Camera Link interface. Image data from the camera are received by the frame grabber card and transmitted to the host via the PCIe interface. The modular structure of MTCA.4 architecture allows connecting several cameras to a single MTCA chassis. The system can operate in two modes: with internal CPU installed in the MTCA chassis or with external CPU connected to the chassis with PCIe link. The usage of the external CPU opens a possibility to aggregate data from different subsystems. The system supports precise synchronization with the time reference using Precise Timing Protocol (IEEE 1588). The timing modules ensure clock distribution and triggers generation on backplane lines. These allow synchronization of image acquisition from different cameras with high precision. The software support for the system includes low-level drivers and API libraries for all components and a high-level EPICS-based environment for system control and monitoring.

Abstract-Modern Low Level Radio Frequency (LLRF) control systems of linear accelerators are designed to achieve extremely precise field amplitude and phase regulation inside superconducting cavities. One of the crucial components of the feedback loop is a vector modulator used to drive the high power RF chain supplying accelerating cavities. The LLRF control systems for the Free Electron Laser in Hamburg (FLASH) and European X-ray Free Electron Laser (XFEL) are based on emerging Micro-Telecommunications Computing Architecture (MTCA, µTCA) platform offering numerous advantages for high performance control systems.This paper describes the concept, design and performance evaluation of world's first Vector Modulator (uVM) module dedicated for LLRF systems compatible with MTCA specification. The module has been designed as a double-width, mid-size AMC form factor Rear Transition Module (RTM) according to developed by PCI Industrial Computer Manufacturers Group (PICMG), MTCA.4 specification.The uVM board incorporates digital, analog and diagnostic subsystems. The digital part is based on Xilinx Spartan 6 family FPGA, with several fast gigalink connections to control module. The uVM module is equipped with an Intelligent Platform Management Interface (IPMI) circuit required by MTCA.4 standard. The FPGA controls the analog part, which includes fast, highprecision DACs, IQ modulator chips, programmable attenuators, power amplifier and fast RF gates for external interlock system. The RF chain can be adopted to different carrier frequencies covering frequency range from 50 MHz to 6 GHz. The design has been carefully optimized for high linearity and low output signal phase noise. The diagnostic system of RF chain allows to monitor input and output power levels and detect failure in RF part. Low noise and high performance clocking system makes the uVM an universal device for applications exceeding the LLRF control system. Extensive tests of the board were performed and measurement results are presented and discussed in this paper.
