	XAL is a Java framework for developing accelerator physics applications for the commissioning and operation of the Spallation Neutron Source. It was designed to be extensible and has evolved to support ongoing accelerator operations. In particular, the on-line model and applications have been extended to support the Ring. Core XAL design features eased the extension from Linac to Ring support and in some cases made it transparent. We discuss the recent advances and future directions in XAL and the current efforts to open the project to broader collaboration.

	J-PARC accelerator complex consists of a proton linac (LINAC), > a Rapid Cycle Synchrotron (RCS), and a Main Ring synchrotron (MR). The commissioning of LINAC already started in November 2006, while the commissioning of Main Ring synchrotron (MR) is scheduled in May 2008. Most of the machine components of MR have been installed in the tunnel. Introduction of electronic modules and wiring will be made by the end of 2007. For the control of MR, the J-PARC accelerator control network was extended to include the MR related parts in March 2007. IOC computers (VME-bus computers) for MR will be introduced in 2007. In addition, more server computers for application development will be also introduced in 2007. This paper reports the status of development for the J-PARC MR control system.

TPPA06	EPICS-Based Control System for Beam Diagnostics of J-PARC LINAC	controls, linac, diagnostics, rfq	96

	A commercial measurement instrumentation (WE7000) is used at J-PARC LINAC, to measure beam current from SCT (Slow Current Transformer), beam energy from FCT (Fast Current Transformer), beam position from BPM (Beam Position Monitor), beam size from WSM (Wire Scanner Monitor), or beam loss from BLM (Beam Loss Monitor). The WE7000 is a module-type measurement station, and supports network-based data transmission and communication. A control system has been developed under EPICS framework for the beam diagnostic system to control all WE stations. A waveform signal from a SCT, a FCT, a BPM, a WSM, or a BLM is digitized in a WE7000 station and sent to an EPICS IOC. All signal voltages are calculated inside IOC from a raw digital count. Some physical variables are calculated from the signal voltages including beam current, beam position, and beam phase and beam energy. An EPCIS device driver was reutilized for the data acquisition. The GUI applications for data displays have been developed by using EPICS extensions tools. The current status is reported in this paper about the beam diagnostic system control.
WOPA03	LHC Software Architecture [LSA] – Evolution Toward LHC Beam Commissioning	controls, injection, collider, optics	307

	The LHC Software Architecture (LSA) project will provide homogenous application software to operate the Super Proton Synchrotron accelerator (SPS), its transfer lines, and the LHC (Large Hadron Collider). It has been already successfully used in 2005 and 2006 to operate the Low Energy Ion Ring accelerator (LEIR), SPS and LHC transfer lines, replacing the existing old software. This paper presents an overview of the architecture, the status of current development and future plans. The system is entirely written in Java and it is using the Spring Framework, an open-source lightweight container for Java platform, taking advantage of dependency injection (DI), aspect oriented programming (AOP) and provided services like transactions or remote access. Additionally, all LSA applications can run in 2-tier mode as well as in 3-tier mode; thus the system joins benefits of 3-tier architecture with ease of development and testability of 2-tier applications. Today, the architecture of the system is very stable. Nevertheless, there are still several areas where the current domain model needs to be extended in order to satisfy requirements of LHC operation.

	CERN’s Accelerator Controls group launched a project in 2003 to develop the new CERN accelerator Real-Time Front-End Software Architecture (FESA) for the LHC and its injectors. In this paper, we would like to report the status of this project, at the eve of the LHC start-up. After describing the main concepts of this real-time Object Oriented Software Framework, we will present how we have capitalized on this technical choice by showing the flexibility through the new functionalities recently introduced such as Transactions, Diagnostics, Monitoring, Management of LHC Critical Settings, and Communication with PLC devices. We will depict the methodology we have put in place to manage the growing community of developers and the start of a collaboration with GSI. To conclude we will present the extensions foreseen in the short term.

	Baseline design of the Taiwan photon Source (TPS) control system of NSRRC is proposed. The control system design is based on EPICS toolkits due to it has large user base in synchrotron light source around the world. Guidelines for hardware platform and operating system choice will be addressed. The standard hardware interface driver is developing and testing now. The asynchronous driver of EPICS will be applied to be the most of standard hardware interface. The expected control system for TPS will provide versatile environments for machine commissioning, operation, and research. The open architecture led machine upgrade or modify without toil. Fewer efforts for machine maintenance are essential. Performance and reliability of the control system will be guarantee form the design phase. Design consideration will be summary in this report.
RPPB21	Finite State Machines for Integration and Control in ALICE	controls, monitoring, injection, heavy-ion	650

	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.
