  For operation of the three undulator systems of the European XFEL, a total of 91 undulators are needed and have been produced. For production, magnetic measurements, tuning and commissioning of these devices only two years were foreseen by the project schedule. For these purposes, automated and optimized procedures were needed to accomplish a number of workflows, time-consuming adjustments and commissioning tasks. We created several automation programs which allowed us to reduce the time spent on the commissioning of the control system by an order of magnitude.

  SSC-LINAC control system is based on EPICS architecture. The sub control system of digital power supplies is a kind of IOC send and receive custom command via Ethernet and TCP/IP protocol. The old IOC is designed to use period scan mode IOC, and there are so many digital power supplies, that we can't make sure every connect condition of digital power supply is fine. IOC must wait a long time if one of them can't connect correctly and other digital power supply's PV may also be blocked. An IOC that uses interrupt driven mode to avoid the shortcoming was designed. This will be described in this paper.

  NICA (Nuclotron based Ion Collider fAcility) is an accelerator complex, which is being built in JINR (Dubna, Russia). The system described in this paper is controlling the RF stations of booster, the first element of the NICA complex. The two devices are parts of the Control System: Intellectual Controller and Tester module. The first one is designed for precise measurement of magnetic field, generation of the acceleration frequency in accordance with measured field and control RF power and pre-amplifiers. Intellectual Controller is a real-time feed-forward system with 20 ums loop time. It is based on ARM microcontroller and bare-metal control programs are used to reach maximum performance. Approaches that were used to achieve maximum performance are elaborated and presented in this paper. The second part of system - Tester is a simulator for tuning and checking the RF stations before start of operations or in absence of real accelerator. The achieved accuracy in chain 'magnetic field' - 'acceleration frequency' is better than 5*10-5. Plans on feedback incorporation to stabilize ion beam behavior via frequency and phase tuning are discussed.

MOPGF090 Control of Fast-Pulsed Power Converters at CERN Using a Function Generator/Controller timing, controls, network, software 1
  • R. Murillo-Garcia, Q. King, M. Magrans de Abril
    CERN, Geneva, Switzerland
  The electrical power converter group at CERN is responsible for the design of fast-pulsed power converters. These generate a flat-top pulse of the order of a few milliseconds. Control of these power converters is orchestrated by an embedded computer, known as the Function Generator/Controller (FGC). The FGC is the main component in the so-called RegFGC3 chassis, which also houses a variety of purpose-built cards. Ensuring the generation of the pulse at a precise moment, typically when the beam passes, is paramount to the correct behaviour of the accelerator. To that end, the timing distribution and posterior handling by the FGC must be well defined. Also important is the ability to provide operational feedback, and to configure the FGC, the converter, and the pulse characteristics. This paper presents an overview of the system architecture as well as the results obtained during the commissioning of this control solution in CERN's new Linac4.

  The Italian National Institute for Astrophysics (INAF) manages three radio telescopes: the Medicina and Noto dishes and the newly-built SRT. In order to make their capabilities more valuable to the scientific community, we started the DISCOS (Development of the Italian Single-dish COntrol System) project. DISCOS is implemented according to a distributed Component-Container model and hides to the users the differences among the telescopes by presenting the same user interface and the same data format. The complexity of coping with three heterogeneous instruments was handled designing a software development infrastructure with a wide monolithic codebase (libraries, components and generic interfaces), which is completely shared among the three product lines. This design permits to produce new software components with a minimum effort and to set up the same test suites for all the environments, thus leading to an affordable development and maintenance process. In this paper we illustrate the design strategies and the development techniques used to realize and optimize this common control software. We also provide a description of the project status and future plans.

  CAN bus is a recommended fieldbus at CERN. It is widely used in the control systems of the experiments to control and monitor large amounts of equipment (IO devices, front-end electronics, power supplies). CAN nodes are distributed over busses that are interfaced to the computers via PCI or USB CAN interfaces. These interfaces limit the possible evolution of the Detector Control Systems (DCS). For instance, PCI cards are not compatible with all computer hardware and new requirements for virtualization and redundancy require dynamic reallocation of CAN bus interfaces to different computers. Additionally, these interfaces cannot be installed at a different location than the front-end computers. Ethernet based CAN interfaces resolve these issues, providing network access to the field busses. The Ethernet-CAN gateways from Analytica (GmbH) were evaluated to determine if they meet the hardware and software specifications of CERN. This paper presents the evaluation methodology and results as well as highlighting the benefits of using such gateways in experiment production environments. Preliminary experience with the Analytica interfaces in the DCS of the CMS experiment is presented.

MOPGF122 A Fast Interlock Detection System for High-Power Switch Protection FPGA, kicker, interface, operation 1
  • P. Van Trappen, E. Carlier, S. Uyttenhove
    CERN, Geneva, Switzerland
  Fast pulsed kicker magnet systems are powered by high-voltage and high-current pulse generators with adjustable pulse length and amplitude. To deliver this power, fast high-voltage switches such as thyratrons and GTOs are used to control the fast discharge of pre-stored energy. To protect the machine and the generator itself against internal failures of these switches several types of fast interlocks systems are used at TE-ABT (CERN Technology department, Accelerator Beam Transfer). To get rid of this heterogeneous situation, a modular digital Fast Interlock Detection System (FIDS) has been developed in order to replace the existing fast interlocks systems. In addition to the existing functionality, the FIDS system will offer new functionalities such as extended flexibility, improved modularity, increased surveillance and diagnostics, contemporary communication protocols and automated card parametrization. A Xilinx Zynq®-7000 SoC has been selected for implementation of the required functionalities so that the FPGA (Field Programmable Gate Array) can hold the fast detection and interlocking logic while the ARM® processors allow for a flexible integration in CERN's Front-End Software Architecture (FESA) framework, advanced diagnostics and automated self-parametrization.

  White Rabbit is an extension of Ethernet which allows remote synchronization of nodes with jitters of around 10ps. The technology can be used for a variety of purposes. This paper presents a fixed-latency trigger distribution system for the study of instabilities in the LHC. Fixed latency is achieved by precisely time-stamping incoming triggers, notifying other nodes via an Ethernet broadcast containing these time stamps and having these nodes produce pulses at well-defined time offsets. The same system is used to distribute the 89us LHC revolution tick. This paper also describes current efforts for distributing multiple RF signals over a WR network, using a Distributed DDS paradigm.

  This paper describes the phase-locked loop algorithms that are used by the real-time power converter controllers at CERN. The algorithms allow the recovery of the machine time and events received by an embedded controller through WorldFIP or Ethernet-based fieldbuses. During normal operation, the algorithm provides less than 10 μs of time precision and 0.5 μs of clock jitter for the WorldFIP case, and less than 2.5 μs of time precision and 40 ns of clock jitter for the Ethernet case.

  The High Repetition-Rate Advanced Petawatt Laser System (HAPLS) forms part of the European Union's Extreme Light Infrastructure Beamlines project (ELI-Beamlines) which will be the first international laser research infrastructure of its kind. HAPLS will generate peak powers greater than one petawatt at a repetition rate of 10 Hz with 30fs wide pulses. ELI will enable unprecedented techniques for many diverse areas of research. HAPLS requires a high-precision timing system that operates either independently or synchronized with ELI's system. Greenfield Technology, a producer of mature picosecond timing systems for several years, has been hired by LLNL* to provide just such a timing system. It consists of a central Master Timing Generator (MTG) that generates and transmits serial data streams over an optical network that synchronizes local multi-channel delay generators which generate trigger pulses to a resolution of 1ps. The MTG is phase-locked to an external 80 MHz reference that ensures a jitter of less than 10ps. The various qualities and functions of this timing system are presented including the LabVIEW interface and precision phase locking to the 80MHz reference.
*LLNL is operated by Lawrence Livermore National Security, LLC, for the U.S. Department of Energy, National Nuclear Security Administration under Contract DE-AC52-07NA27344.

  The Computer-on-Module approach makes cutting edge technology easily accessible and lowers the entry barriers to anyone prototyping and developing embedded systems. Furthermore, it is possible to add all the system specific functionalities to the generic PC functions which are readily available in an off-the-shelf core module reducing the time to market and enhancing the creativity of system engineers. The purpose of this paper is to show a custom hardware platform based on the tiny and low power Intel Edison Compute Module, which uses a 22nm Intel processing core and contains connectivity elements to ensure device-to-device and device-to-cloud connectivity. The Intel Edison carrier board designed is expected to act as a local intelligent node, a readily available custom EPICS*,** IOC for extending the control reach to small appliances in the context of the SPES project. The board acts as an Ethernet to RS232/RS422 interface translator with Power-Over-Ethernet supply and network booting as key features of this platform. The x86 architecture of the Edison makes standard Linux software deployment straightforward. Currently the board is in prototyping stage.

  In this paper, we report the conceptual design of control networks used in the control system for China initiative accelerator driven sub-critical (ADS) facility which consists of two accelerator injectors, a main accelerator, a spallation target and a reactor. Because different applications have varied expectations on reliability, latency, jitter and bandwidth, the following networks have been designed for the control systems, i.e. a central operation network for the operation of accelerators, target, and reactor; a reactor protection network for preventing the release of radioactivity to the environment; a personnel protection network for protecting personnel against unnecessary exposure to hazards; a machine protection network for protecting the machines in the ADS system; a time communication network for providing timing and synchronization for three accelerators; and a data archiving network for recording important measurement results from accelerators, target and reactor. Finally, we discuss the application of high-performance Ethernet technologies, such as Ethernet ring protection protocol, in these control networks for CIADS.

The 3.8 km circumference Relativistic Heavy Ion Collider (RHIC) at BNL has been in operation since 2000. An electron-ion collider (eRHIC), which is in the design phase, plans to use one of the existing ion rings and new electron rings constructed in the existing tunnel to provide collisions of up to 21.2 GeV electrons with up to 100 GeV gold ions, 250 GeV polarized protons, as well as other species. Many new real-time systems will be required to satisfy the needs of eRHIC, including over 2000 beam position monitors, 1000 beam loss monitors, 18 current monitors, feedback systems, controls for about 10,000 power supplies, machine protection system, new beam timing systems, and more. The selected architecture must be flexible, expandable, cost-effective, reliable, and easy to maintain. Interface with existing and new accelerator timing systems is required, and compatibility with existing infrastructure and equipment must be maintained. Embedded modules based on the Xilinx Zynq gate array, with direct Ethernet connection and on-board Linux, housed in multi-slot chassis (VME, VPX, TCA, etc.) is under consideration. Preliminary design concepts for the architecture will be presented.

  In this paper, we report the design of the control system for the spallation target in China initiative accelerator driven sub-critical (ADS) system, where a heavy-metal target located vertically at the centre of a sub-critical reactor core is bombarded vertically by the high-energy protons from an accelerator. The main functions of the control system for the target are to monitor and control thermal hydraulic, neutron flux, and accelerator-target interface. The first function is to control the components in the primary and secondary loops, such as pumps, heat exchangers, valves, sensors, etc. For the commissioning measurements of the accelerator, the second function is to monitor the neutrons from the spallation target. The three-layer architecture has been used in the control system. In the middle network layer, in order to increase the network reliability, the redundant Ethernet based on Ethernet ring protection protocol has been considered. In the bottom equipment layer, the equipment controls for the above-mentioned functions have been designed. Finally, because the main objective of the target is to integrate the accelerator and the reactor into one system, the integration of accelerator's control system and the reactor's instrumentation and controls into the target's control system has been mentioned.
