WECOMA01	Use of the Cell Accelerator Platform for Synchrotron Data Analysis	synchrotron, target, feedback, lattice	4

	The analysis of synchrotron-based Polychromatic X ray Microscoscopy (PXM) data has been used by scientists and engineers to understand elastic and plastic strains in materials on aμor nano scale. Such experiments generate hundreds or thousands of images where the analysis of each image often entails intensive computations- a challenging task. As well, in the past, the speed of such computations has made it difficult to obtain feedback on the experimental results in near real time. This has constrained researchers from making critical decisions on direction subsequent experiments should take based on the results in hand. In order to improve the analysis performance of PXM images, we have investigated the use of parallel analysis schemes. This paper reports on the design and implementation of accelerated PXM analysis software that has been developed on IBM PowerXCell 8i processors and Intel quad-core Xeon processors. A substantial improvement in processing speed has been obtained to the extent that it should be possible to obtain analysis results at the same rate as they are produced on the VESPERS beamline at the Canadian Light Source Synchrotron(~1 Hz) .

WECOAA01	Tango Collaboration News	controls, survey, feedback, diagnostics	16
	J. M. Meyer ESRF, Grenoble
	During the last years, the Tango collaboration was and is still growing. More and more users are requesting new features and developing new tools for Tango. Decisions whether the requested features will be implemented and whether new tools will be part of the Tango distribution need to be made. The organizational aspects of the collaboration need to be clarified as well as the decision making process for new developments. This paper will explain the collaboration, its organization and the decision making process as well as the latest facts and features around Tango. Some ongoing developments are the new code generation tool to allow inheritance in the Tango class structure, the new event system for high bandwidth event distribution and the Tango packaging to allow installation with a few clicks.

WEPL003	The Beamline Experiments Scheduling Software	synchrotron, controls	33
	Y. Yan, C. Wang, Z. Wang, L. Zhao, Y. Zhu Concordia University, Montreal
	Beamline scheduling is a manual procedure at the Canadian Light Source (CLS) so far. In the current manual procedure, the beamline scientists are responsible for scheduling all the approved experiments. They normally start by scheduling the experiments with higher priority, and try to schedule as many experiments as possible within the beamline operating cycle. As there are many constraints on resource capability, availability, user preferences, as well as priorities to consider, no one has ever been able to check if the manual scheduling results are optimal or not. In the Canarie funded project Science Studio, we are building an automatic scheduling module as part of the User Office software. The synchrotron users submit their proposals via the User Office. The automatic scheduling algorithm can give an optimal scheduling solution. In this paper, we present our contributions: 1) modeling the synchrotron proposal scheduling problem and solving it using integer programming; 2) design and implementation of the scheduling module within the framework of the User Office; 3) integrating the commercial scheduling tool ILOG CPLEX tool to our system.

WEPL029	Applicability of XAL for ESS	controls, lattice, simulation, linac	85

	XAL is a Java based application framework, developed at the Spallation Neutron Source (SNS). The framework is designed to provide an accelerator physics programming interface to the accelerator and it allows writing general purpose applications dedicated to various parts of the accelerator. The backbone of XAL framework is an XML based description of the accelerator. The XML file provides the list of all devices, their properties, and in-between devices relations within the system. Since the accelerator structure is defined in the relational database, the XML can be generated directly out from the database using appropriate adapters. This allows the framework to be more generic and enables it to run on different sites using various configurations. The generality of the XAL and the rich set of applications and tools provided by SNS make the framework very appealing for usage at other accelerator sites. European Spallation Source (ESS) is being built in Sweden, which will be in overall an accelerator similar to SNS. Therefore, XAL has been considered to be used at ESS for high-level applications. The applicability of XAL and prototyping for ESS will be discussed in this article.

WEPL033	EPICS IOCcore Real-Time Performance Measurements on Coldfire Module*	target, controls, photon	94
	S. Xu, R. Laird, F. Lenkszus, H. Shang ANL, Argonne
	Since EPICS (Experimental Physics and Industrial Control System) is gaining use in accelerator control systems and because the EPICS Input/Output Controller (IOC) has been ported to different operating systems, the performance of EPICS IOCcore on different hardware and software platforms is becoming important. This paper will provide real-time performance measurements of EPICS IOCcore on a Coldfire module uc5282 and two different OS platforms: RTEMS 4.9 and uClinux 2.6. The most recent EPICS base and extensions are used to build the test application.

THPL023	Data Acquisition and Studies of Vibration Motion in TLS Beamlines	electron, photon, controls, feedback	177

	TPS (Taiwan Photon Source) is being under construction while TLS (Taiwan Light Source) is still on operation at the same NSRRC site. It was observed that the stability of photon beam intensity (Io) of TLS seemed a little deteriorated at daytime, when civil work is busy, compared to the nighttime. The intensity changes at different beamlines, however, aren’t consistent with each other in each time, furthermore not so agreeing with the electron beam. Therefore, to correlate how the ground vibration due to civil construction effected on beam behaviour, the vibration measurement system is integrated into the existing TLS control system. The system will support waveform acquisition which could be acquired on demand. Meanwhile, realtime 10 Hz rms detector which could be archived continuously is also considered to be built in the future.
