  In the accelerator domain there is a need of integrating industrial devices and creating control and monitoring applications in an easy and yet structured way. The LabVIEW-RADE framework provides the method and tools to implement these requirements and also provides the essential integration of these applications into the CERN controls infrastructure. Building and distributing these core libraries for multiple platforms, e.g.Windows, Linux and Mac, and for different versions of LabVIEW, is a time consuming task that consist of repetitive and cumbersome work. All libraries have to be tested, commissioned and validated. Preparing one package for each variation takes almost a week to complete. With the introduction of Subversion version control (SVN) and Hudson continuous integration server (HCI) the process is now fully automated and a new distribution for all platforms is available within the hour. In this paper we are evaluating the pros and cons of using continuous integration, the time it took to get up and running and the added benefits. We conclude with an evaluation of the framework and indicate new areas of improvement and extension.

  A general control system of the Materials and Life science experimental Facility (MLF-GCS) consists of programmable logic controllers (PLCs), operator interfaces (OPI) of iFix, data servers, and so on. It is controlling various devices such as a mercury target and a personnel protection system. The present system has been working well but there are problems in view of maintenance and update because of poor flexibility of OS and version compatibility. To overcome the weakness of the system, we decided to replace it to an advanced system based on EPICS and CSS as a framework and OPI software, which has advantages of high scalability and usability. Then we built a prototype system, connected it to the current MLF-GCS, and examined its performance. As the result, the communication between the EPICS/CSS system and the PLCs was successfully implemented by mediating a Takebishi OPC server, true data of 7000 were stored with suitable speed and capacity in a new data storage server based on a PostgreSQL, and OPI functions of the CSS were verified. We concluded through these examinations that the EPICS/CSS system had function and performance specified to the advanced MLF-GCS.

    CERN, Geneva, Switzerland
  
  Periodically the alignment of LHC collimators needs to be verified. Access for personnel is limited due to the level of radiation close to the collimators. The required measurements precision must be comparable to the other equipment in the LHC tunnel, meaning 0.15 mm in a sliding window of 200 m. Hence conventional measurements would take 4 days for a team of 3 people. This presentation covers the design, development and commissioning of a remotely controlled system able performs the same measurements in 1 h with one operator. The system includes the integration of a variety of industrial devices ranging from position sensors, inclination sensors to video cameras, all linked to a PXI system running LabVIEW. The control of the motors is done through a PLC based system. The overall performance and user experience are reported.

  LabVIEW is widely used for experimental station control in SPring-8. LabVIEW is also partially used for accelerator control, while most software of the SPring-8 accelerator and beamline control are built on MADOCA control framework. As synchrotron radiation experiments advances, there is requirement of complex data exchange between MADOCA and LabVIEW control systems which was not realized. We have developed next generation MADOCA called MADOCA II, as reported in this ICALEPCS (T.Matsumoto et.al.). We ported MADOCA II framework to Windows and we developed MADOCA II interface for LabVIEW. Using the interface, variable length data can be exchanged between MADOCA and LabVIEW based softwares. As a first application, we developed a readout system for an electron beam position monitor with NI's PCI-5922 digitizers. A client software sends a message to a remote LabVIEW based digitizer readout software via the MADOCA II midlleware and the readout system sends back waveform data to the client. We plan to apply the interface various accelerator and synchrotron radiation experiment controls.

  The beamline instruments at the ISIS spallation neutron source have been running successfully for many years using an in-house developed control system. The advent of new instruments and the desire for more complex experiments has led to a project being created to determine how best to meet these challenges. Though it would be possible to enhance the existing system, migrating to an EPICS-based system offers many advantages in terms of flexibility, software reuse and the potential for collaboration. While EPICS is well established for accelerator and synchrotron beamline control, is it not currently widely used for neutron instruments, but this is changing. The new control system is being developed to initially run in parallel with the existing system, a first version being scheduled for testing on two newly constructed instruments starting summer 2013. In this paper, we will discuss the design and implementation of the new control system, including how our existing National Instruments LabVIEW controlled equipment was integrated, and issues that we encountered during the migration process.

  Beamlines at LNLS are moving to the concept of distributed control under EPICS. This has being done by reusing available code from the community and/or by programming hardware access in LabVIEW integrated to EPICS through Hyppie. Hyppie is a project to make a bridge between EPICS records and corresponding devices in a PXI chassis. Both EPICS/Linux and LabVIEW Real-Time run simultaneously in the same PXI controller, in a virtualization system with a common memory block shared as their communication interface. A number of new devices were introduced in the Hyppie suite and LNLS beamlines are experiencing a smooth transition to the new concept.

  The 4B beamline of the Pohang Light Source-II performs X-ray microdiffraction and microfluorescence experiments using X-ray microbeams. The microbeam has been focused down to FWHM sizes of less than 3 μm by manually adjusting the vertical and horizontal focusing mirrors of a K-B (Kirkpatrick-Baez) mirror system. In this research, a microbeam-focusing automation software was developed to automate the old complex and cumbersome process of beam focusing which may take about a day. The existing controllers of the K-B mirror system were replaced by products with communication functions and a motor-driving routine by means of proportional feedback control was constructed. Based on the routine and the outputs of two ionization chambers arranged in front and rear of the K-B mirror system, the automation software to perform every step of the beam focusing process was completed as LabVIEW applications. The developed automation software was applied to the 4B beamline and showed the performance of focusing an X-ray beam with a minimal size within an hour. This presentation introduces the details of the algorithms of the automation software and examines its performances.

  A high-speed data acquisition system was successfully developed and put into production in a harsh radiation environment in a couple of months to test new materials impacted by proton beams for future use in beam intercepting devices. A 4 MHz ADC with high impedance and low capacitance was used to digitize the data at a 2 MHz bandwidth. The system requirements were to design a full speed data streaming on a trigger during up to 30 ms and then reconfigure the hardware in less than 500 ms to perform a 100 Hz acquisition for 30 seconds. Experimental data were acquired, using LabVIEW real-time, relying on extensive embedded instrumentation (strain gauges and temperature sensors) and on acquisition boards hosted on a PXI crate. The data acquisition system has a dynamic range and sampling rate that are sufficient to acquire the very fast and intense shock waves generated by the impact. This presentation covers the requirements, the design, development and commissioning of the system. The overall performance, user experience and preliminary results will be reported.

  At CERN, many digitizers and scopes are starting to age and should be replaced. Much of the equipment is custom made or not available on the market anymore. Replacing this equipment with the equivalent of today would either be time consuming or expensive. This paper looks at the pros and cons of using COTS systems like NI-cRIO and NI-PXIe and their FPGA capabilities as flexible instruments, replacing costly spectrum analyzers and older scopes. It adds some insight on what had to be done to integrate and deploy the equipment in the unique CERN infrastructure, and the added value of having a fully customizable platform, that makes it possible to stream, store and align the data without any additional equipment.

Many of our machines have a lot in common – they drive motors, take pictures, generate signals, toggle switches, and observe and measure effects. In a research environment that creates new machines and expects them to perform for a production assembly line, it is important to meet both schedule and quality. NIF has developed a LabVIEW layered architecture of Support, general Frameworks, Controllers, Devices, and User Interface Frameworks. This architecture provides a tested and qualified framework of software that allows us to focus on developing and testing the external interfaces (hardware and user) of each machine.

  ARM microcontrollers have high processing speed and low power consumption because they work efficiently with less memory by their own instruction set. Therefore, ARM microcontrollers are used not only in portable devices but also other commercial electronic devices. In recent years, free development environments and low-cost development kits are provided by many companies. The “mbed” provided by NXP is one of them. The “mbed” provides an environment where we can develop a product easily even if we are not familiar with electronics or microcontrollers. We can supply electric power and can transfer the program that we have developed by connecting to a PC via USB. We can use USB and LAN that, in general, require high level of expertise. The “mbed” has also a function as a HTTP server. By combining with JavaScript library, we can control multiple I/O ports at the same time through LAN. In the presentation, we will report the results that we applied the “mbed” to develop an RF signal switching system for a turn-by-turn beam position monitor (BPM) at a synchrotron light source, UVSOR-III.

  In Kyoto University Research Reactor Institute (KURRI), a fixed-field alternating gradient (FFAG) proton accelerator complex, which is consists of the three FFAG rings, had been constructed to make an experimental study of accelerator driven sub-critical reactor (ADSR) system with spallation neutrons produced by the accelerator. The world first ADSR experiment was carried out in March of 2009. In order to increase the beam intensity of the proton FFAG accelerator, a new injection system with H− linac has been constructed in 2011. To deal with these developments, a control system of these accelerators should be easy to develop and maintain. The first control system was based on LabVIEW and the development had been started seven years ago. Thus it is necessary to update the components of the control system, for example operating system of the computer. And the first control system had some minor stability problems and it was difficult for non-expert of LabVIEW to modify control program. Therefore the EPICS toolkit has been started to use as the accelerator control system in 2009. The present control system of the KURRI FFAG complex is explained.

  The Large Hadron Collider (LHC) at CERN requires many systems to work in close interplay to allow reliable operation and at the same time ensure the correct functioning of the protection systems required when operating with large energies stored in magnet system and particle beams. The systems for magnet powering and beam operation are qualified during dedicated commissioning periods and retested after corrective or regular maintenance. Based on the experience acquired with the initial commissioning campaigns of the LHC magnet powering system, a framework was developed to orchestrate the thousands of tests for electrical circuits and other systems of the LHC. The framework was carefully designed to be extendable. Currently, work is on-going to prepare and extend the framework for the re-commissioning of the machine protection systems at the end of 2014 after the LHC Long Shutdown. This paper describes concept, current functionality and vision of this framework to cope with the required dependability of test execution and analysis.

  Synchrotron accelerators with multiple ion sources and beam lines require a high degree of flexibility to define beam cycle timing sequences. We have therefore decided to design a ready-to-use accelerator timing system based on off-the-shelf hardware and software that can fit mid-size accelerators and that is easy to adapt to specific user needs. This Real Time Event Distribution Network (REDNet) has been developed under the guidance of CERN within the MedAustron-CERN collaboration. The system based on the MRF transport layer has been implemented by Cosylab. While we have used hardware on NI PXIe platform, it is straightforward to obtain it for other platforms such as VME. The following characteristics are key to its readiness for use: (1) turn-key system comprising hardware, transport layer, application software and open integration interfaces, (2) performance suitable for a wide range of accelerators, (3) multiple virtual timing systems in one physical box, (4) documentation developed according to V-model. Given the maturity of the development, we have decided to make REDNet available as a product through our industrial partner.

  Programmable Logic Controller (PLC) is very commonly used in many industries and research applications for process control. However a very complex process control may require algorithms and performances beyond the capability of PLCs, very high-speed or precision controls may also require other solutions. This paper describes recent research conducted to implement advanced process controls with the cRIO material from National Instruments (decoupling of MIMO process control, steady state feedback, observer, Kalman filter, etc…). The cRIO systems consist of an embedded real-time controller for communication and processing, a Reconfigurable Field Programmable Array (FPGA) and hot-swappable I/O modules. The paper presents experimental results and the ability of the cRIO to treat complex process control.
