	A user interface (UI) framework supports the development of graphical operator controls for the National Ignition Facility (NIF) Integrated Computer Control System (ICCS). The framework simplifies UI coding and ensures consistency for system operators across all NIF subsystems. A comprehensive, layered collection of UIs provides interaction with service-level frameworks, shot automation, and subsystem-specific devices. All user interfaces are written in Java and employ CORBA to interface to other ICCS components. Developers use the framework to compose two major types of user interfaces for broad-views and control panels. Broad-views provide a visual representation of NIF beamlines through interactive schematic drawings. Control panels present status and control at the device level. The UI framework provides a suite of display components that standardize user interaction through data entry behaviors, common connection and threading mechanisms, and a common appearance. With these components, developers can address pattern usability issues in the facility when needed. The UI framework helps developers create consistent and easy-to-understand user interfaces for NIF operators.

	The TITAN experiment at the ISAC radioactive beam facility consists of an RF cooler system, a Magnetic Penning Trap (MPET), and an Electron Beam Ion Trap (EBIT). These three systems may run together or independently. This paper describes the EPICS-based TITAN control system, which was modeled after the ISAC control system to facilitate integration. Both software and hardware configurations will be described, with emphasis on pulsed diagnostics and the pulse distribution system for synchronizing the traps in different operation modes.
WPPB03	Software Interlocks System	controls, laser, injection, diagnostics	403

	In the year 2006, a first operational version of a new Java-based Software Interlock System (SIS) was introduced to protect parts of the SPS (Super Proton Synchrotron) complex, mainly CNGS (CERN Neutrinos to Gran Sasso), TI8 (SPS transfer line), and for some areas of the SPS ring. SIS protects the machine through surveillance and by analyzing the state of various key devices and dumping or inhibiting the beam if a potentially dangerous situation occurs. Being a part of the machine protection, it shall gradually replace the old SPS Software Interlock System (SSIS) and reach the final operational state targeting LHC (Large Hadron Collider) in 2008. The system, which was designed with the use of modern, state-of-the-art technologies, proved to be highly successful and very reliable from the very beginning of its existence. Its relatively simple and very open architecture allows for fast and easy configuration and extension to meet the demanding requirements of the forthcoming LHC era.

	A prototype data processing board for a digital spill control system has been made. The system is considered to be used to control proton beams in 50-GeV synchrotron rings of J-PARC. The prototype circuit board consists of four ADCs, two FPGAs, a DSP, memories, and four DACs. The four inputs of the processing board are assumed to be an intensity signal of the proton beam in the accelerator rings, a digital gate signal that indicates the duration of beam extraction, a spill signal that shows the intensity of the extracted proton beam, and a reserved signal. The resolution and maximum sampling speed of the ADC are 16 bit and 2.5 Msps, respectively. One of the FPGAs is Vartex-2 1000-4C, and a real-time power spectrum analyzer will be implemented. It analyzes the spill signal every 1ms or shorter period. The analyzed result reflects optimum parameters used in spill control by servo. The DSP takes charge of these digital servo processing. The DACs with 16-bit resolution drive control signals for magnet currents. The system has another FPGA for communication between the processing board and network. MicroBlase CPU core is implemented, and uCLinux is installed to use EPICS.
WPPB24	High Dynamic Range Current Measurements with Machine Protection	SNS, target, beam-transport, injection	448
	D. A. Bartkoski, C. Deibele, C. Sibley, D. H. Thompson ORNL, Oak Ridge, Tennessee
	At the SNS a beam current measurement technique called CHuMPS (Chopper Machine Protection System) has been developed that is fast, has a large dynamic range, and is droop-free. Combined with the LEBT chopper controller, a beam in gap measurement is possible that can accurately measure the beam in the chopper gaps. The beam in gap measurement can then provide machine protection in the case of chopper failure. The same application can also measure waste beam from the ring injection stripper foil and provide fast protection from stripper foil failure.
ROAA03	Injection, Ramping and Extraction Timing for the Duke Booster	booster, injection, storage-ring, controls	491

	A booster synchrotron capable of ramping from 0.25 to 1.2 GeV was recently commissioned at Duke University as part of the High Intensity Gamma Source upgrade. The triggering and timing system uses a combination of software logic and triggers, digital delay generators, and hardware synchronizers to coordinate the linac injector, booster synchrotron and electron storage ring. The injection system has been commissioned with a short pulse photo-injector linac into a single booster RF bucket and to two booster buckets separated by about half the circumference. It has also been commissioned with a long electron pulse from the injection linac into all 19 buckets. The extraction system, combined with short pulse kickers, can extract any of the booster's 19 electron bunches in to any of the storage ring's 64 bunches. Ramping is controlled by programmable VME based waveform generators triggered from the timing system. The system offers flexibility for commissioning and operations and provides a simple interface to the operator.

RPPA27	Status of the TANGO Archiving System	controls, synchrotron, monitoring, vacuum	570
	J. Guyot, M. O. Ounsy, S. Pierre-Joseph Zephir SOLEIL, Gif-sur-Yvette
	This poster will give a detailed status of the major functionality delivered as a Tango service: the archiving service. The goal of this service is to maintain the archive history of thousands of accelerators or beamline control parameters in order to be able to correlate signals or to get snapshots of the system at different times and to compare them. For this aim, three database services have been developed and fully integrated in Tango: an historical database with an archiving frequency up to 0.1 Hz, a short-term database providing a few hours retention but with higher archiving frequency (up to 10 HZ), and finally a snapshotting database. These services are available to end users through two graphical user interfaces: Mambo (for data extraction/visualization from historical and temporary databases) and Bensikin (for snapshots management). The software architecture and design of the whole system will be presented, as well as the current status of the deployment at SOLEIL.
RPPB05	Applying Agile Project Management for Accelerator Controls Software	controls, laser, feedback, injection	612
	N. Stapley, W. Sliwinski CERN, Geneva
	Developing accelerator controls software is a challenging task requiring not only a thorough knowledge of the different aspects of particle accelerator operations, but also application of good development practices and robust project management tools. Thus, there was a demand for a complete environment for both developing and deploying accelerator controls software, as well as the tools to manage the whole software life cycle. As an outcome, a versatile development process was formulated, covering the controls software life cycle from the inception phase up to the release and deployment of the deliverables. A development environment was created providing management tools that standardize the common infrastructure for all the concerned projects; help to organize work within project teams; ease the process of versioning and releasing; and provide an easy integration of the test procedures and quality assurance reports. Change management and issue tracking are integrated with the development process and supported by the dedicated tools. This approach was successfully applied for all the new controls software for LEIR, SPS, LHC, injection lines, and CNGS extraction.
RPPB14	Systematic Production of Beamline and Other Turnkey Control Systems	controls, target, background, site	632

	Turnkey oriented accelerator control system production is often quite complex and challenging. It involves software development as well as substantial project management effort and, almost always, an on-site installation. Most of the labs have developed solutions that to some extent support such processes, but are tailored to the lab's particular needs and environment. We could not recycle these solutions, as we had to keep the choices open for defining the naming convention and choosing the operating system, platform, and even the control system. Based on our experience with control systems, we have defined a complete set of processes that prescribe the highest level of quality and efficiency in all the project segments. To implement these processes, we have developed a number of tools for composing, configuring, and deploying the control system software. Use of these tools enforces strict version control and traceability, enables centralized configuration of the system, and largely reduces the possibility of human errors. These tools also enable us to reuse well-tested building blocks, leaving us more time for system-wide quality assurance.
RPPB31	Distributed Timing Diagnostic Applications	controls, diagnostics, kicker, injection	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.
