WOAB01	Operational Tools at the Stanford Linear Accelerator Center	288
	S. Chevtsov, P. Chu, D. Fairley, C. Larrieu, D. Rogind, H. Shoaee, M. Woodley, S. Zelazny, G. R. White SLAC, Menlo Park, California
	The operational tools at SLAC have been in continuous development for 20 years. These include a highly developed orbit correction package, an automatic bump maker, orbit fitting, lattice diagnostics, beta-matching and phase advance calculator, a macro recording facility, "Correlation Plots," which is a facility for conducting small ad-hoc experiments, plus a number of others. All of these use a global online modeling database system, and they are all integrated into a single interactive application program, so they interoperate seamlessly. In this talk I'll review these tools, and contrast them with systems we have recently developed which focus on support for accelerator physics conducted directly from numerical analysis packages such as Matlab, or from physicists' own small specialized programs. Lastly, our plans to rewrite all of these operational tools using modern software tools and infrastructure, and how we bridge old systems to new, will be presented.

WOAB02	CAD Model and Visual Assisted Control System for NIF Target Area Positioners	293
	T. S. Paik, E. F. Wilson, E. A. Tekle LLNL, Livermore
	The National Ignition Facility (NIF) contains precision motion control systems that reach up to 6 meters into the target chamber for handling targets and diagnostics. Systems include the target positioner, an alignment sensor, and diagnostic manipulators. Experiments require a variety of arrangements near chamber center to be aligned to an accuracy of 10 micrometers. These devices are some of the largest in NIF, and they require careful monitoring and control in three dimensions to prevent interferences. Alignment techniques such as viewing target markers and cross-chamber telescopes are employed. Positioner alignment is a human-control process incorporating real-time video feedback on the user interface. The system provides efficient, flexible controls while also coordinating all positioner movements. This is accomplished through advanced video-control integration incorporating remote position sensing and real-time analysis of a CAD model of target chamber devices. This talk discusses the control system design, the method used to integrate existing mechanical CAD models, and the offline test laboratory used to verify proper operation of the integrated control system.

WOAB03	Development of Accelerator Management Systems with GIS	296
	Y. Ishizawa, A. Yamashita JASRI/SPring-8, Hyogo-ken
	We have been developing accelerator management systems for SPring-8 on Geographic Information System (GIS). Those systems are, in short, "Google maps for accelerators". Users enjoy interactive acclerator maps on web browsers with zooming, panning, ruler, image overlay and multi-layer display features. We applied an open-source GIS, MapServer, for the systems. We have build two web-based systems on MapServer. Accelerator inventory management system displays equipment locations on the map reading data from a relational database. It displays not only locations of equipment but also detailed attributes by clicking symbols on the interactive map. Users also can enter their own data or upload their own files from the web browser to store into the database. Another SCSS alarm system desplays real-time alarm locations on the map. The alarm database build on the MADOCA system serves real-time and static data for alarm display. We will show mechanism and development of those systems in the paper.

WOAB04	Web-Based Electronic Operation Log System – Zlog System	299
	K. Furukawa, T. T. Nakamura, T. Obina, M. Satoh, N. Yamamoto KEK, Ibaraki T. Nakamura, K. Yoshii MELCO SC, Tsukuba
	A Zope-based electronic operation logging system, named Zlog system, has been used since January 2004 at the KEKB and PF-AR accelerator facilities at KEK. Zope* is a Web content management system, which is based on several open source software components like Python and Postgresql. It enabled us to develop our Zlog in a short period, because the Zope system includes a development framework for Web application server. Zlog was introduced also to J-PARC/KEK-JAEA and RIBF/RIKEN, based on the experiences at KEKB and PF-AR. Zlog was proved to be quite portable even under different computer architectures. Zlog at KEKB accumulates about 1.5 million event entries so far, and images taken during the operation can be stored and viewed as well with entries. In this paper, we describe the present status and component details of the Zlog system. * http://www.zope.org/

RPPB01	The CERN Control Centre: Setting Standards for the 21st Century	603
	D. Manglunki CERN, Geneva
	After a 15-month construction period, the CERN Control Centre (CCC) began operating on February 1st, 2006. The CCC now controls all of CERN's accelerators, technical infrastructure, and cryogenics plants. In addition, most LHC experiments as well as other scientific laboratories throughout the world, are adopting some of its design options (furniture, layout, colours, …) for their own control rooms. This paper presents the main ideas behind the ergonomic choices.
RPPB03	Alarms Configuration Management	606
	R. Martini, K. Sigerud, N. Stapley, A. S. Suwalska, P. Sollander CERN, Geneva
	The LHC alarm service, LASER, is the alarm tool used by the operators for the accelerators and the technical services at CERN. To ensure that the alarms displayed are known and understood by the operators, each alarm should go through a well-defined procedure from its definition to being accepted in operation. In this paper we describe the workflow to define alarms for the technical services at CERN. We describe the different stages of the workflow like equipment definition, alarm information specification, control system configuration, test, and final acceptance in operation. We also describe the tools available to support each stage and the actors involved. Although the use of a strict workflow will limit the number of alarms that arrive to LASER and ensure that they are useful for operations, for a large complex like CERN there are still potentially many alarms displayed at one time. Therefore the LASER tool provides facilities for the operators to manage and reduce the list of alarms displayed. The most important of these facilities are described, together with other important services like automatic GSM and/or e-mail notification and alarm system monitoring.
RPPB04	SNS Logbook	609
	M. Giannella, B. V. Horn, J. G. Patton, T. A. Pelaia ORNL, Oak Ridge, Tennessee
	An electronic logbook has been developed for the Spallation Neutron Source. This logbook serves as a means of chronologically recording daily operations activities and experiences and communicating them to appropriate groups. The logbook is database-driven and integrates into our existing database schema. The interface to the logbook is web-based and works with most modern web browsers on the major platforms. Additionally, a Java package provides a simple mechanism to post entries from within our XAL applications.
RPPB06	Device Control Tool for CEBAF Beam Diagnostics Software	615
	P. Chevtsov Jefferson Lab, Newport News, Virginia
	By continuously monitoring the beam quality in the CEBAF accelerator, a variety of beam diagnostics software created at Jefferson Lab makes a significant contribution to very high availability of the machine for nuclear physics experiments. The interface between this software and beam instrumentation hardware components is provided by a device control tool, which is optimized for beam diagnostics tasks. As a part of the device/driver development framework at Jefferson Lab, this tool is very easy to support and extend to integrate new beam instrumentation devices. All device control functions are based on the configuration (ASCII text) files that completely define the used hardware interface standards (CAMAC, VME, RS-232, GPIB) and communication protocols. The paper presents the main elements of the device control tool for beam diagnostics software at Jefferson Lab.
RPPB07	The System Overview Tool of the Joint Controls Project (JCOP) Framework	618
	M. Gonzalez-Berges, F. Varela CERN, Geneva K. D. Joshi BARC, Mumbai
	For each control system of the Large Hadron Collider (LHC) experiments, there will be many processes spread over many computers. All together, they will form a PVSS distributed system with around 150 computers organized in a hierarchical fashion. A centralized tool has been developed for supervising, error identification and troubleshooting in such a large system. A quick response to abnormal situations will be crucial to maximize the physics usage. The tool gathers data from all the systems via several paths (e.g., process monitors, internal database) and, after some processing, presents it in different views: hierarchy of systems, host view and process view. The relations between the views are added to help to understand complex problems that involve more than one system. It is also possible to filter the information presented to the shift operator according to several criteria (e.g. node, process type, process state). Alarms are raised when undesired situations are found. The data gathered is stored in the historical archive for further analysis. Extensions of the tool are under development to integrate information coming from other sources (e.g., operating system, hardware).
RPPB08	The Development of Detector Alignment Monitoring System for the ALICE ITS	621
	M. G. Cherney, Y. N. Gorbunov, R. P. Thomen, J. Fujita Creighton University, Omaha, NE T. J. Humanic, B. S. Nilsen, J. Schley, D. Trusdale Ohio State University
	A real-time detector alignment monitoring system has been developed by using commodity USB cameras, spherical mirrors, and laser beams introduced via a single mode fiber. An innovative control and online analysis software has been developed by using the OpenCV (Open Computer Vision) library & PVSS (Prozessvisualisierungs- und Steuerungssystem). This system is being installed in the ALICE detector to monitor the position of ALICE's Inner Tracking System subdetector. The operational principle and software implementation will be described.
RPPB10	Use of E-Logbook in VEPP-5 Control System	624
	D. Bolkhovityanov, R. E. Kuskov BINP SB RAS, Novosibirsk
	An electronic logbook (e-logbook) becomes a must for large experimental facilities not only during operation, but also at building and commissionning stages (where VEPP-5 is now). Unfortunately, the "market" of such products is almost nonexistent. So, the choice is narrow: either use some other lab's software (adapting it for local needs) or create your own one from scratch. We have chosen the former way and picked DOOCS e-logbook from DESY. Main changes concerned localization (since Russian uses cyrillic letters, not latin) and data feeding mechanism (due to different model of logging from applications). Integration with GIS and alarm system is being examined.
RPPB11	EPICS CA Gateway Employment in the BEPCII Network	627
	J. Liu, C. H. Wang, Y. H. Wang, Z. Zhao, X. H. Huang IHEP Beijing, Beijing
	The control network of the BEPCII is divided into two separate different subnets. In order to access IOC PVs between the separate subnets as well as IOC PVs from the campus network, we adopt EPICS CA gateway in the BEPCII network. This paper describes the EPICS CA gateway employment and network management in the BEPCII .
RPPB13	The First Stage of the Post Mortem Analysis Software Used for the Hardware Commissioning of the LHC	629
	B. Khomenko, D. Kudryavtsev, H. Reymond, A. Rijllart, N. Trofimov, A. Raimondo CERN, Geneva
	After a failure during the operation of the LHC, leading to a beam abort or a power abort, a coherent set of so called “Post Mortem” information will be collected from the various subsystems to analyze the causes of failure. To be able to understand the failure before resuming LHC operation, the collected information needs to be analysed within a few minutes and this requires a highly automated analysis system. To develop the Postm Mortem Analysis software, we use a staged approach by providing self-contained software modules, first for the individual systems, such as the Quench Protection System, the Power Converter and the Power Interlock Controller, and second for the hardware commissioning when these systems will interact. All of these modules are made using LabVIEW and form the building blocks of the final Post Mortem Analysis software. A large part of the code developed over the last years for the quality test of the LHC magnets has been reused, profiting from the similarity of the algorithms. This paper describes the present state and the additional stages needed to build the final system.
RPPB16	SPARCbook: A New Electronic Book	638
	A. Cianchi INFN-Roma II, Roma S. Fioravanti, E. Pace INFN/LNF, Frascati (Roma)
	Many electronic books exist for logging the activity of an accelerator, but all of them are basically a translation of a paper book in an electronic format, with some extra features coming from the usage of a database for storing the information. SPARCbook is based on PostgreSQL, an open source database. A new, nice GUI has been developed for manually inserting data (both text and pictures) in the logbook and retrieving the old information, using several filters like date, author, or type of information. This GUI has been developed using HTML, PHP, and JavaScript, and it is quite similar to GUIs of already existing electronic logbooks. The peculiarity of SPARCbook is that it is also possible to insert information in the book from the control system of the accelerator, automatically or after a human decision. The SPARC control system is a distributed system, developed using LabVIEW, based on PCs and real-time CPUs. Information, tables, and graphs can be submitted from each CPU and from the central control system to SPARCbook making a query to PostgreSQL via TCP. That makes the system really powerful because any commercial CPU has TCP capability.
RPPB19	Electron Bunch Length Measurement for LCLS at SLAC	644
	S. Allison, S. Chevtsov, P. Emma, K. D. Kotturi, H. Loos, S. Peng, D. Rogind, T. Straumann, S. Zelazny SLAC, Menlo Park, California
	At Stanford Linear Accelerator Center (SLAC) a Bunch Length Measurement system has been developed to measure the length of the electron bunch for its new Linac Coherent Light Source (LCLS). This destructive measurement uses a transverse-mounted RF deflector (TCAV) to vertically streak the electron beam and an image taken with an insertable screen and a camera. The device control software was implemented with the Experimental Physics and Industrial Control System (EPICS) toolkit. The analysis software was implemented in Matlab using the EPICS/Channel Access Interface for Scilab and Matlab (labCA). This architecture allowed engineers and physicists to develop and integrate their control and analysis without duplication of effort.
RPPB20	A Graphical Sequencer for SOLEIL Beamline Acquisitions	647
	A. Buteau, M. O. Ounsy, G. Abeille SOLEIL, Gif-sur-Yvette
	Addressing batch processing and sequencing needs are fundamentals for daily beamlines operation. The SOLEIL control software group offers two solutions. Firstly, the Python scripting environment, for which a dedicated Tango binding is available, has been proved to be powerful, but is limited to scientists with good programming skills. Secondly, we provide the PASSERELLE software, developed by the ISENCIA* company and based on the PTOLEMY** framework. In this environment, sequences can be designed graphically by drag and drop components called actors (representing elementary tasks). The process execution can be easily “programmed” by defining graphically the data flow between actors. Upon this framework, an existing generic GUI application allows users to configure and execute the sequences. A dedicated GUI application can also be provided on demand to give the beam line’s end user an easy-to-use acquisition application. The work organization, the software architecture and design of the whole system will be presented, as well as the current status of deployment on SOLEIL beamlines. * http://www.isencia.com/main/web/init** http://ptolemy.eecs.berkeley.edu/ptolemyII/index.htm
RPPB21	Finite State Machines for Integration and Control in ALICE	650
	A. Augustinus, M. Boccioli, P. Ch. Chochula, L. S. Jirden, G. De Cataldo CERN, Geneva
	From the control point of view a physics experiment can be seen as a vast hierarchy of systems and subsystems with an experiment control node at the top and single atomic control channels at the bottom. In the case of the ALICE experiment at CERN the many systems and subsystems are being built by many engineers and physicists in different institutes around the world. The integration of the various parts to form a homogeneous system enabling coherent automatic control can therefore be seen as a major challenge. A distributed PVSS SCADA system complemented with a device and system modeling schema based on finite state machines has been used to achieve this. This paper will describe the schema and the tools and components that have been developed at CERN and it will show how this has been implemented and used in Alice. The efforts of standardizing the state diagrams for different types of devices and systems at different levels will be described and some detailed examples will be shown. The Alice graphics user interface integrating both the FSM control hierarchy and the PVSS monitoring will also be described.
RPPB22	Tracking Accelerator Settings	653
	W. Fu, D. P. Ottavio, T. D'Ottavio BNL, Upton, Long Island, New York
	Recording setting changes within an accelerator facility provides information that can be used to answer questions about when, why, and how changes were made to some accelerator system. This can be very useful during normal operations, but can also aid with security concerns and in detecting unusual software behavior. The Set History System (SHS) is a new client/server system developed at the Collider-Accelerator Department of Brookhaven National Laboratory to provide these capabilities. The SHS has been operational for over two years and currently stores about 100K settings per day into a commercial database management system. The SHS system consists of a server written in Java, client tools written in both Java and C++, and a web interface for querying the database of setting changes. The design of the SHS focuses on performance, portability, and a minimal impact on database resources. In this paper, we present an overview of the system design along with benchmark results showing the performance and reliability of the SHS over the last year.
RPPB23	SCORE – A Save, Compare, and Restore Application for Snapshotting Machine Settings	656
	J. G. Patton, T. A. Pelaia, J. Galambos ORNL, Oak Ridge, Tennessee
	SCORE is an application used to snapshot machine settings. Features include sorting by systems and subsystems, comparing live values with saved values, and database storage of the information. The compare feature is useful for diagnosing problems, and the restore feature is useful in recovering good beam tune. Features of the application and performance experience with respect to data base retrieval and live comparison will be discussed.
RPPB24	Processing and Visualization of EPICS Data with MATLAB Applications	659
	E. Tikhomolov TRIUMF, Vancouver
	To conserve control system resources it is often desirable to run compute-intensive real-time data processing applications on a dedicated host computer. In the EPICS-based control system of the ISAC radioactive beam facility, the Extensible Display Manager tool (EDM) is used for the operator interface. EDM screens control data acquisition and processing and provide visualization of the processed data. Matlab is used as the data processing engine. A number of Matlab applications were created in collaboration with the beam physics group. These applications are running on a dedicated Linux host, using EPICS Matlab Channel Access (MCA) to obtain raw data from beam diagnostic IOCs (Linux-based) and store the processed results in the IOC. The raw data are provided to the IOC by fast data acquisition applications through a shared memory interface.
RPPB25	Live Capfast Schematics in the ISAC Control System	662
	R. B. Nussbaumer TRIUMF, Vancouver
	The Capfast schematic editor is used to design EPICS IOC runtime databases in the EPICS-based control system of the ISAC radioactive beam facility. This graphical tool provides a view of the database with strong visual cues about the functional behavior of the database elements and their interrelationships, modularity, and hierarchy. The EDM display manager tool is used for the Human-Machine-Interface, providing a graphical view of the accelerator state to machine operators. This paper describes a new tool, Sch2Edl, which combines some of the functionality of Capfast and EDM. Sch2Edl creates a view of the runtime database in a format geared toward the system developer/tester/debugger. Sch2Edl is a perl script that translates a set of Capfast schematic files into a corresponding set of EDM screens. The visual representation of the runtime database on the EDM display is nearly identical to the static Capfast views and hierarchies, but incorporates the display of real-time data. This allows software developers to examine and modify some aspects of a working runtime database in an environment that is rich in visual information.
RPPB26	The New Soft-IOC-Based Alarm Handler at the Spallation Neutron Source	665
	G. S. Lawson, J. Munro, W. H. Strong, E. Williams, P. A. Gurd ORNL, Oak Ridge, Tennessee
	The standard EPICS alarm handler tool (ALH) does not integrate well with other EPICS client applications. At SNS, we wanted the ability to incorporate alarm summaries and alarm controls such as masks and resets into screens in the display manager as well as the ability to call display screens from alarm screens. To achieve these aims, we built a soft-IOC-based alarm handler that runs in Linux soft IOCs. A set of scripts builds EPICS databases, display manager screens, and startup scripts for standard Linux soft IOCs from old style (ALH) or .xml configuration files. With this new tool the summaries, masks and latch status can be incorporated into other EPICS client applications. In this paper we describe our experience building and using the soft-IOC-based alarm handler everywhere that alarms are defined in the SNS control system. SNS is managed by UT-Battelle, LLC, under contract DE-AC05-00OR22725 for the U. S. Department of Energy.
RPPB27	A Proposed Alarm Handling System Management Plan for SNS with Application to Target Control System	668
	R. E. Battle, E. Danilova, R. L. Sangrey, E. Williams, J. Munro ORNL, Oak Ridge, Tennessee
	We have developed a set of requirements for an SNS alarm handling system and have applied these to the control system for the SNS liquid mercury target to gain experience with an implementation first on a limited scale before applying them to the whole accelerator. This implementation is based on the EPICS alarm handler ALH. The requirements address such topics as alarm classification, priorities, types of warning, hierarchies, and management under different modes of target operation. Alarms are currently organized by system and subsystem. Target control systems considered in the examples here include the Hg loop, three light-water and one heavy-water cooling loops. Modifications to ALH include addition of “drag and drop” capabilities for individual PVs and drop-down lists of selectable actions. One such action provides access to the alarm response procedures required for a process variable that shows an alarm. Alarm and operator action log files are maintained separately from instances of ALH launched for operator displays. Database reporting tools have been developed to aid analysis of data in these files. Examples of the use of our tools and features will be presented.
RPPB28	BESSY Control System Administration and Analysis Tools	671
	T. Birke, D. Faulbaum, D. Herrendörfer, P. Stange, R. Lange BESSY GmbH, Berlin M. G. Giacchini INFN/LNL, Legnaro, Padova
	The BESSY II storage ring has been in continuous operation for more than 8 years. With BESSY's new projects and facilities requiring an increasing amount of attention, maintaining the BESSY II control system's high reliability and availability with less effort has become an important task. A set of professional noncommercial tools has been introduced. These tools are combined to detect and track errors, support system administration, and allow an efficient analysis and maintenance of the control system's hardware, software, and configuration. The paper discusses problems and difficulties encountered, and presents the selected approaches and tools as well as the gained experiences.
RPPB29	Requirements and Coherent Realization of the HICAT Control System Functionality for Test, Commissioning, and Operation	674
	R. Baer, M. Schwickert, T. Fleck GSI, Darmstadt
	The control system for the HICAT project comprises several rather different functionalities for the whole range of demands starting from tests of single components up to the specified operation mode where the accelerator has to deliver a beam of high-energy ions with requested energy, focus and intensity for tumor treatment. We outline the concept and realization of this system which is capable of fulfilling all those needs within the implemented functions and GUIs. The range of functionality spans from test environments and trace-possibilities for single front-end controllers up to complete integrity tests of the whole accelerator for the designed operation mode. For example, for commissioning of the LINAC division the control system utilizes a 5Hz mode while typical synchrotron cycles last for several seconds and can be used with similar adjustments. In normal operation mode diagnostics like beam current are only evaluated at special times in a cycle, but it is possible to monitor and record these data at high sampling rates in a continuous mode over several hours. Furthermore it is possible to accomplish long-term stability tests of single components during normal operation.
RPPB31	Distributed Timing Diagnostic Applications	677
	I. Kozsar, J. H. Lewis, J. Serrano, P. Kennerley CERN, Geneva
	The CERN timing system delivers events to the accelerator complex via a distribution network to receiver modules located around the laboratory. These modules generate pulses for nearby equipment and interrupts for the local host. Despite careful planning, hardware failure and human error can lead to anomalies within the control system. Diagnosing such errors requires a formal description of the logical and topological timing layout. This paper describes the design and implementation of a suite of timing diagnostic software applications that allow users to quickly diagnose and remedy faults within the CERN timing system.
RPPB32	A MySQL-based Data Archiver: Preliminary Results	680
	C. J. Slominski, M. Bickley Jefferson Lab, Newport News, Virginia
	Following an evaluation of the archival requirements of the Jefferson Laboratory accelerator's user community, a prototyping effort was executed to determine if an archiver based on mySql had sufficient functionality to meet those requirements. This approach was chosen because an archiver based on a relational database enables the development effort to focus on data acquisiti and management, letting the database take care of storage, indexing and data consistency. It was clear from the prototype effort that there were no performance impediments to successful implementation of a final system. With our performance concerns addressed, the lab undertook the design and development of an operational system. The system is in its operational testi phase now. This paper discusses the archiver system requirements, some of th design choices and their rationale, and presents the acquisition, storage and retrieval performance levels achieved with the system.
RPPB34	Global Search Tool for the Advanced Photon Source Integrated Relational Model of Installed Systems (IRMIS) Database	683
	M. B. Cianciarulo Purdue University, West Lafayette, Indiana D. E.R. Quock ANL, Argonne, Illinois
	The Integrated Relational Model of Installed Systems (IRMIS) is a relational database tool that has been implemented at the Advanced Photon Source to maintain an updated account of approximately 600 control system software applications, 400,000 process variables, and 30,000 control system hardware components. To effectively display this large amount of control system information to operators and engineers, IRMIS was initially built with nine Web-based viewers: Applications Organizing Index, IOC, PLC, Component Type, Installed Components, Network, Controls Spares, Process Variables, and Cables. However, since each viewer is designed to provide details from only one major category of the control system, the necessity for a one-stop global search tool for the entire database became apparent. The user requirements for extremely fast database search time and ease of navigation through search results led to the choice of Asynchronous JavaScript and XML (AJAX) technology in the implementation of the IRMIS global search tool. Unique features of the global search tool include a two-tier level of displayed search results, and a database data integrity validation and reporting mechanism.
RPPB35	Administration of Control Systems at the Advanced Photon Source Using Applications Organizing Index	686
	N. D. Arnold, D. E.R. Quock ANL, Argonne, Illinois
	Applications Organizing Index (AOI) is a relational database tool that has been implemented at the Advanced Photon Source (APS) to aid in the management of more than 600 unique control system applications. AOI provides control system developers an intuitive view of and navigation links to the components that make up a single control system such as source code files, operator displays, process variables, work history notes, programmable components, validation procedures, drawings, and more. The foundation for the Applications Organizing Index tool is the collaborative effort between several Experimental Physics and Industrial Control System (EPICS) sites to build the common relational database schema for documenting large and complex particle accelerator control systems, Integrated Relational Model of Installed Systems (IRMIS). This paper describes the evolution of AOI as it became populated with APS control systems component data and as users’ requests for new features of AOI became apparent.
ROPB01	Using Sequencing to Improve Operational Efficiency and Reliability	689
	J. Niedziela, T. D'Ottavio BNL, Upton, Long Island, New York
	Operation of an accelerator requires the efficient and reproducible execution of many different types of procedures. Some procedures, like beam acceleration, magnet quench recovery, and species switching can be quite complex. To improve accelerator reliability and efficiency, automated execution of procedures is required. Creation of a single robust sequencing application permits the streamlining of this process and offers many benefits in sequence creation, editing, and control. In this paper, we present key features of a sequencer application commissioned at the Collider-Accelerator Department of Brookhaven National Laboratory during the 2007 run. Included is a categorization of the different types of sequences in use, a discussion of the features considered desirable in a good sequencer, and a description of the tools created to aid in sequence construction and diagnosis. Finally, highlights from our operational experience are presented, with emphasis on Operations control of the sequencer, and the alignment of sequence construction with existing operational paradigms.

ROPB03	Drag and Drop Display & Builder	695
	A. D. Petrov, T. B. Bolshakov Fermilab, Batavia, Illinois
	The "Drag and Drop Display & Builder" system is a component-oriented system that is designed to allow users to create visual representations of data received from data acquisition systems. It is an upgrade of a synoptic display mechanism used in Fermilab since 2002. Components can be graphically arranged and logically interconnected in the web-startable Project Builder. Projects can be lightweight AJAX and SVG based web pages, or they can be started as Java applications. The system may be used to control equipment if started as a Java application. The new version was initiated as a response to discussions between the LHC Controls Group and Fermilab.

ROPB04	Beam Commissioning Software and Database for J-PARC LINAC	698
	C. K. Allen LANL, Los Alamos, New Mexico H. Ikeda Visual Information Center, Inc., Ibaraki-ken H. Sakaki, G. B. Shen, H. Takahashi, H. Yoshikawa JAEA, Ibaraki-ken H. Sako JAEA/J-PARC, Tokai-Mura, Naka-Gun, Ibaraki-Ken
	A beam commissioning software system based on a relational database (RDB) has been developed for the J-PARC LINAC. We developed two high-level software frameworks, JCE and XAL. JCE (Java Commissioning Environment) based on a scripting language SAD script has been developed in Java with device control, monitoring, online modelling and data analysis functions. XAL has been developed initially by SNS and developed for J-PARC. A commissioning database system has been developed to configure commonly these two frameworks, for model geometry, EPICS control, and calibration parameters. A server for unit conversion of magnet power supplies has also developed for the commissioning software. Commissioning applications for RF tuning, transverse matching, orbit correction, beam-based calibration, beam monitor controls have been developed using the two framework and successfully applied for beam tuning. We report on the status of development for the commissioning software system.
