Refurbishment of the ESRF Accelerator Synchronization System Using White Rabbit

224

ESRF, Grenoble, France

The ESRF timing system, dating from the early 90's and still in operation, is built around a centralized RF driven sequencer distributing synchronization signals along copper cables. The RF clock is broadcasted over a separate copper network. White Rabbit, offers many attractive features for the refurbishment of a synchrotron timing system, the key one being the possibility to carry RF over the White Rabbit optical fiber network. CERN having improved the feature to provide network-wide phase together with frequency control over the distributed RF, the whole technology is now mature enough to propose a White Rabbit based solution for the replacement of the ESRF system, providing flexibility and accurate time stamping of events. We describe here the main features and first performance results of the WHIST module, an ESRF development based on the White Rabbit standalone SPEC board embedding the White Rabbit protocol and a custom mezzanine (DDSIO) extending the FMC-DDS hardware to provide up to 12 programmable output signals. All WHIST modules in the network run in phase duplicates of a common RF driven sequencer. A master module broadcasts the RF and the injection trigger.

THBPL06

High Performance RDMA-Based Daq Platform Over PCIe Routable Network

Funding: Wassim Mansour acknowledges support from the EUCALL project which has received funding from the European Union's H2020 research and innovation programme under grant agreement No 654220.
The ESRF initiated few years ago the development of a novel platform for optimised transfer of 2D detector data based on zero-copy Remote Direct Memory Access techniques. The purpose of this new scheme, under the name of RASHPA, is to efficiently dispatch with no CPU intervention multiple parallel multi-GByte/s data streams produced by modular detectors directly from the detector head to computer clusters for data storage, visualisation and distributed data treatment. The RASHPA platform is designed to be implementable using any data link and transfer protocol that supports RDMA write operations and that can trigger asynchronous events. This paper presents the ongoing work for the first implementation of RASHPA in a real system using the hardware platform of the Medipix3 based SMARTPIX hybrid pixel detector developed at ESRF and relying on switched PCIe over cable network for data transfer. It details the implementation of the RASPHA controller at the detector side and provides input on the software for the management of the overall data acquisition system at the receiver side. The implementation and use of a PCIe switch built with components off-the-shelf is also discussed.

THPHA072

A Position Encoder Processing Unit

1557

R. Hino, P. Fajardo, N. Janvier, T. Le Caër, F. Le Mentec
ESRF, Grenoble, France

Typical motion controllers rely on a feedback position encoder to detect the actuator output and correct for external factors. Recent advancements in positioning systems increased the demand for the ability to process a variety of sensors and use the result to feedback the motion controller. In addition, data acquisition tools are becoming essential for metrology purposes to diagnose and analyse the behaviour of the system. A multi-sensor, multi-protocol unit with processing and data acquisition capabilities has been developed to address these requirements. Here we describe the main features of this unit, its internal architecture, and few examples of application.

The ICALEPCS MOCRAF workshop group has been created on www. MOCRAF.org to discuss about the organization of the ICALEPCS Motion Control pre-conference Workshop. Its purpose is to get feedback from attendees to make the workshop as interesting and as pleasurable as possible. This group will remain alive after the workshop to be the input for the future ICALEPCS MOCRAF meeting. The aim of the workshop is to be helpful to you the community and so we welcome input (*) on the content and style. After the previous workshop in at ICALEPCS in Melbourne it was suggested that more time should be put aside for interactive group discussions. We are proposing two talks per session each of around 15 to 20 minutes leaving 50 - 60 minutes for relevant discussion topics.
