[en] RIKEN Radioactive Isotope Beam Factory (RIBF) is a cyclotron-based next-generation radioactive beam facility. RIBF uses two types of control systems; an experimental physics and industrial control system (EPICS)-based system and a group of several non-EPICS-based systems. For each control system there is a corresponding data archiving system in operation, and in order to unify these two data archives, since October 2009 we have been developing a new archiving system. This new data archive system, named RIBF Control Data Archive System (RIBFCAS), is required, at intervals between 1 - 60 s, to collect and store more than 3000 data generated by EPICS controlled devices through EPICS input/output controllers (IOCs). In addition, RIBFCAS must be able to combine the existing non-EPICS-based systems. To fulfill these requirements, a Java-based platform has been created, and client applications are based on Adobe AIR runtime. The RIBFCAS hardware system, therefore, consists of an application server, a database server and client-PCs. Presently, we have succeeded in stably acquiring approximately 3000 data from 22 IOCs every 10 s. Moreover, incorporation of the non-EPICS-based data archive system into RIBFCAS is now in progress.

[en] Initially the relational database (RDB) for control system configuration at BESSY has been built around the device concept. Maintenance and consistency issues as well as complexity of scripts generating the configuration data, triggered the development of a novel, generic RDB structure based on hierarchies of named nodes with attribute/ value pairs. Unfortunately, it turned out that usability of this generic RDB structure for a comprehensive configuration management relies on sophisticated data maintenance tools. On this background BDNLS, a new database management tool, is currently under development using the framework of the Eclipse Rich Client Platform. It uses the Model View Controller (MVC) layer of JFace to cleanly separate retrieval processes, data path, data visualization and actualization. It is based on extensible configurations defined in XML allowing to chain SQL calls and compose profiles for various cases. It solves the problem of data key forwarding to the subsequent SQL statement. BDNLS has the potential to map various levels of complexity into the XML configurations. This provides usable, tailored database access to configuration maintainers for different underlying database structures. Based on Eclipse, the integration of BDNLS into Control System Studio is straight forward. (authors)

[en] The Taiwan Photon Source (TPS) is a 3 GeV synchrotron light source which is being in construction at NSRRC. The BPM (Beam Position Monitors) electronics with the latest generation FPGA and new mechanical form factor to enhance functionality of current generation products will be employed for the TPS. The prototype BPM electronics is testing. To achieve the stringent orbit stability goal of the TPS, orbit feedback system is designed to eliminate beam motions due to various perturbation sources. The design and implementation plan of the BPM system and the orbit feedback system are summarized in this report. (authors)

[en] At PSI (Paul Scherrer Institute) there are two facilities with proton cyclotron accelerators. The machine control system for PROSCAN which is used for medical patient therapy, is running with EPICS. The High Intensity Proton Accelerator (HIPA) is mostly running with the in-house developed control system ACS. The control of dedicated parts of HIPA runs already under EPICS. Both these facilities are configured through an Oracle database application suite. This paper presents the concepts and tools which are used to configure the control system directly from the database stored configurations. Such an approach has advantages which contribute for better control system reliability, overview and consistency. (authors)

[en] The J-PARC accelerator complex comprises proton LINAC, 3-GeV RCS (Rapid Cycling Synchrotron), and 30-GeV MR (Main Ring). The J-PARC is a joint project between JAEA and KEK. Two control systems, one for LINAC and RCS and another for MR, were developed by the two institutes. Both control systems use the EPICS tool-kit, thus, inter-operation between the two systems is possible. After the first beam in 2006, beam commissioning and operation have been successful. The current status of J-PARC control structure is given. Components are introduced and reviewed with reliability issues: a plan to develop new GUI (Graphical User Interface) applications for operators is given. (authors)

[en] Utilities data such as the air temperature in a machine tunnel, power line voltage, and temperature of machine-cooling water are managed by the facility management system. Previously, the accelerator control system could not obtain most of the required utilities data because the accelerator control system and facility management system were independent systems without an interconnection. In 2010, we updated the old facility management system. In order to facilitate data acquisition, we constructed gateways between the MADOCA-based accelerator control system and the new facility management system, installing the BACnet protocol. The data acquisition requirements were as follows: to monitor utilities data with the required sampling rate and resolution, to store all of the acquired data in the accelerator database, to maintain independence between the accelerator control system and the facility management system, to ensure a future expandability to control the facility equipment from the accelerator control system. We out-sourced the gateway construction, including the MADOCA-based data acquisition software, to solve the problems of limited manpower and short work period. In this paper, we describe the system design and the out-sourcing approach. (authors)

[en] At any synchrotron facility, motors are numerous: they are the significant actuators of accelerators and the main actuators of beamlines. Since 2003, the Electronic Control and data Acquisition group at SOLEIL has defined a modular and reliable motion architecture integrating industrial products (Galil controller, Midi-Engineering and Phytron power boards). Simultaneously, the software control group has developed a set of dedicated Tango devices. At present, more than 1000 motors and 200 motion controller crates are in operation at SOLEIL. Aware that motion control is important in improving performance, given that the positioning of optical systems and samples is a key element of any beamline, SOLEIL wants to upgrade its motion controller in order to maintain the facility at a high performance level and be able to respond to new requirements: better accuracy, complex trajectory and coupling multi-axis devices such as hexa-pods. This project is called REVOLUTION (Reconsider Various controllers for your motion). (authors)

[en] The construction of the X-ray free electron laser facility (SACLA) in SPring-8 has started in 2006. After 5 years of construction, the facility has completed to accelerate electron beams in February 2011. The C-band linac accelerates beams up to 8 GeV. The beam size is compressed to a length of 30 fs, and the beams are introduced to the insertion devices to generate 0.06 nm X-ray laser. The first SASE X-ray laser was observed at the beginning of June 2011. The first scientific experiment will start at the end of October this year. The control system for SACLA adopts the 3-tier standard model by using MADOCA framework developed in SPring-8. The upper control layer consists of Linux PCs for operator consoles, Sybase RDBMS for data logging and FC-based NAS for NFS. The lower control layer consists of Solaris-operated VME systems and the PLC is used for slow control. The Device-net is adopted for the front-end devices to reduce signal cables. The beam-synchronized data-taking link is installed to meet 60 Hz beam operation. The accelerator control has gateways to the facility utility system not only to monitor devices but also to control the tuning points of the RF cooling water. (authors)

[en] Recently a Solid State Direct Drive concept for RF linacs has been introduced. This new approach integrates the RF source, comprised of multiple Silicon Carbide (SiC) solid state RF-modules, directly onto the cavity. Such an approach introduces new challenges for the control of such machines namely the non-linear behavior of the solid state RF-modules and the direct coupling of the RF-modules onto the cavity. In this paper we discuss further results of the experimental program to integrate and control 64 RF-modules onto a lambda/4 cavity. The next stage of experiments aims on gaining better feed forward control of the system and on detailed system identification. For this purpose a digital control board comprising of a Virtex 6 FPGA, high speed DACs/ADCs and trigger I/O is developed and integrated into the experiment and used to control the system. The design of the board is consequently digital aiming at direct processing of the signals. Power control within the cavity is achieved by an out-phasing control of two groups of the RF-modules. This allows a power control without degradation of the RF-module efficiency. (authors)

[en] The WebSocket allows asynchronous full-duplex communication between a Web-based (i.e. Java Script-based) application and a Web-server. WebSocket started as a part of HTML5 standardization but has now been separated from HTML5 and has been developed independently. Using WebSocket, it becomes easy to develop platform independent presentation layer applications for accelerator and beamline control software. In addition, a Web browser is the only application program that needs to be installed on client computer. The WebSocket-based applications communicate with the WebSocket server using simple text-based messages, so WebSocket is applicable message-based control system like MADOCA, which was developed for the SPring-8 control system. A simple WebSocket server for the MADOCA control system and a simple motor control application were successfully made as a first trial of the WebSocket control application. Using Google-Chrome (version 13.0) on Debian/Linux and Windows 7, Opera (version 11.0) on Debian/Linux and Safari (version 5.0.3) on Mac OS X as clients, the motors can be controlled using a WebSocket-based Web-application. Diffractometer control application use in synchrotron radiation diffraction experiment was also developed. (author)
