	G. Cuní, F. Becheri, D. Fernández-Carreiras, Z. Reszela, S. Rubio-Manrique ALBA-CELLS Synchrotron, Cerdanyola del Vallès, Spain
	At Alba, the Controls Section provides the software that is needed to operate the accelerators, the beamlines and the peripheral laboratories. It covers a wide range of areas or subsystems like vacuum, motion, data acquisition and analysis, graphical interfaces, or archiving. Since the installation and commissioning phases, we have been producing the software solutions mostly in single-developer projects based on the personal criteria. This organization scheme allowed each control engineer to gain the expertise in particular areas by being the unit contact responsible to develop and deliver products. In order to enrich the designs and improve the quality of solutions we have grouped the engineers in teams. The hierarchy of the product backlogs, represents the desired features and the known defects in a transparent way. Instead of planning the whole project upfront, we try to design the products incrementally and develop them in short iterations mitigating the risk of not satisfying the emerging user requirements. This paper describes the introduction of the Scrum framework as the product development strategy in a service oriented organization like the Computing Division at Alba. D. Fernández-Carreiras et al., 'Using Prince2 and ITIL Practices for Computing Project and Service Management in a Scientific Installation', TUMIB01, Proc. of ICALEPCS'13, San Francisco, CA.

MOPGF065	Motion Control on the Max IV Soft X-Ray Beamlines With Tango and Sardana	controls, GUI, TANGO, software	240
	M. Lindberg, J. Forsberg, L. Kjellsson, A.M. Milan, C. Såthe, P. Sjöblom, S. Urpelainen MAX-lab, Lund, Sweden
	MAX IV Laboratory, a synchrotron facility in Lund, has selected TANGO as the control system framework for the entire facility. On the beamlines that are being built the Python-based SCADA (supervisory control and data acquisition) system Sardana will be used for experimental control. SPECIES, one out of eight new soft X-ray beamlines, is used as a test bench for evaluating the chosen standards. Sardana is used to control the energy setting of the PGM (plane grating monochromator) as well as to provide macros and other utilities for the user. Generic Taurus GUIs and a SVG-synoptic give the user a way to interact with the control system and display relevant information. The standardized graphical interfaces give a familiar look and feel across the entire facility. All motorized axes are controlled with the IcePAP motion controller. For the axes of the PGM, the IcePAP driver operates in hardware closed loop. Special care is taken in order to avoid slow and inaccurate movements of the PGM energy due to the non-linear relationship between the motors and the angular encoders.

MOPGF150	Improving SOLEIL Computing Operation with a Service-Oriented Approach	software, operation, controls, interface	441
	A. Buteau, G. Abeillé, B. Gagey SOLEIL, Gif-sur-Yvette, France J.C. Fouquet JCF, PARIS, France
	SOLEIL Computing division continuously needs to enhance its operational activities and minimize the workload of IT groups because IT performances directly impacts accelerators and beamlines operations in a context of an increase of the overall technical and organizational complexity. The Control & Data Acquisition group changed in 2013 it internal projects and support organization toward a service-oriented approach. This promising first step pointed out that enhancing the service delivered to our customers required to agree with them on a common vocabulary, on semantics and on operational processes. The ITIL* methodology appeared then as very good starting point to this purpose. This paper will describe the overall vision of our project 'Improving IT operation with a service oriented approach' and will detail the first ITIL operational processes we have adopted and how it helped us clarifying roles and responsibilities within our IT organization. In order to conclude the paper will give perspectives of using ITIL practices to enhance operational practices of other technical groups which activities strongly impact the service delivered to SOLEIL end users. *http://en.wikipedia.org/wiki/Information_Technology_Infrastructure_Library

	MASSIVE is the Australian specialised High Performance Computing facility for imaging and visualisation. The project is a collaboration between Monash University, Australian Synchrotron and CSIRO. MASSIVE underpins a range of advanced instruments, with a particular focus on Australian Synchrotron beamlines. This paper will report on the outcomes of the MASSIVE project since 2011, in particular focusing on instrument integration, and interactive access. MASSIVE has developed a unique capability that supports an increasing number of researchers generating and processing instrument data. The facility runs an instrument integration program to help facilities move data to an HPC environment and provide in-experiment data processing. This capability is best demonstrated at the Imaging and Medical Beamline where fast CT reconstruction and visualisation is now essential to performing effective experiments. The MASSIVE Desktop provides an easy method for researchers to begin using HPC, and is now an essential tool for scientists working with large datasets, including large images and other types of instrument data.

WEM303	Virtualisation within the Control System Environment at the Australian Synchrotron	EPICS, controls, hardware, network	664
	C.U. Felzmann, N. Hobbs, A. C. Starritt SLSA, Clayton, Australia
	Virtualisation technologies significantly improve efficiency and availability of computing services while reducing the total cost of ownership. Real-time computing environments used in distributed control systems require special consideration when it comes to server and application virtualisation. The EPICS environment at the Australian Synchrotron comprises more than 500 interconnected physical devices; their virtualisation holds great potential for reducing risk and maintenance. An overview of the approach taken by the Australian Synchrotron, the involved hardware and software technologies as well as the configuration of the virtualisation eco-system is presented, including the challenges, experiences and lessons learnt.

	Often the producers of Big Data face the emerging problem of Data Deluge. Nevertheless experimental facilities such as synchrotrons and free electron lasers may have additional requirements, mostly related to the necessity of managing the access for thousands of scientists. A complete data lifecycle describes the seamless path that joins distinct IT tasks such as experiment proposal management, user accounts, data acquisition and analysis, archiving, cataloguing and remote access. This paper presents the data lifecycle of the synchrotron ELETTRA and the free electron laser FERMI. With the focus on data access, the Virtual Unified Office (VUO) is presented. It is a core element in scientific proposal management, user information DB, scientific data oversight and remote access. Eventually are discussed recent developments of the beamline software, that holds the key role to data and metadata acquisition but also requires integration with the rest of the system components in order to provide data cataloging, data archiving and remote access. The scope of this paper is to disseminate the current status of a complete data lifecycle, discuss key issues and hint on the future directions.

WEPGF049	The Unified Anka Archiving System - a Powerful Wrapper to Scada Systems like Tango and WinCC OA	database, TANGO, controls, interface	810
	D. Haas, S.A. Chilingaryan, A. Kopmann, W. Mexner, D. Ressmann KIT, Eggenstein-Leopoldshafen, Germany
	ANKA realized a new unified archiving system for the typical synchrotron control systems by integrating their logging databases into the "Advanced Data Extraction Infrastructure" (ADEI). ANKA's control system environment is heterogeneous: some devices are integrated into the Tango archiving system, other sensors are logged by the Supervisory Control and Data Acquisition (SCADA) system WinCC OA. For both systems modules exist to configure the pool of sensors to be archived in the individual control system databases. ADEI has been developed to provide a unified data access layer for large time-series data sets. It supports internal data processing, caching, data aggregation and fast visualization in the web. Intelligent caching strategies ensure fast access even to huge data sets stored in the attached data sources like SQL databases. With its data abstraction layer the new ANKA archiving system is the foundation for automated monitoring while keeping the freedom to integrate nearly any control system flavor. The ANKA archiving system has been introduced successfully at three beamlines. It is operating stable since about one year and it is intended to extend it to the whole facility.

	N. Leclercq, J. Bisou, F. Blache, F. Langlois, S. Lê, K. Medjoubi, C. Mocuta, S. Poirier SOLEIL, Gif-sur-Yvette, France
	SOLEIL is continuously optimizing its 29 beamlines in order to provide its users with state of the art synchrotron radiation based experimental techniques. Among the topics addressed by the related transversal projects, the enhancement of the computing tools is identified as a high priority task. In this area, the aim is to optimize the beam time usage providing the users with a fast, simultaneous and multi-technique scanning platform. The concrete implementation of this general concept allows the users to acquire more data in the same amount of beam time. The present paper provides the reader with an overview of so call 'Flyscan' project currently under deployment at SOLEIL. It notably details a solution in which an unbounded number of distributed actuators and sensors share a common trigger clock and deliver their data into temporary files. The latter are immediately merged into common file(s) in order to make the whole experiment data available for on-line processing and visualization. Some application examples are also commented in order to illustrate the advantages of the Flyscan approach.

	Store. Synchrotron is a service for management and publication of diffraction data from the macromolecular crystallography (MX) beamlines of the Australian Synchrotron. Since the start of the development, in 2013, the service has handled over 51.8 TB of raw data (~ 4.1 million files). Raw data and autoprocessing results are made available securely via the web and SFTP so experimenters can sync it to their labs for further analysis. With the goal of becoming a large public repository of raw diffraction data, a guided publishing workflow which optionally captures discipline specific information was built. The MX-specific workflow links PDB coordinates from the PDB to raw data. An optionally embargoed DOI is created for convenient citation. This repository will be a valuable tool for crystallography software developers. To support complex projects, integration of other instruments such as microscopes is underway. We developed an application that captures any data from instrument computers, enabling centralised data management without the need for custom ingestion workflows. The next step is to integrate the hosted data with interactive processing and analysis tools on virtual desktops.

	HDF5 and NeXus (which normally uses HDF5 as its underlying format) have been widely touted as a standard for storing Photon and Neutron data. They offer many advantages to other common formats and are widely used at many facilities. However, it has been found that the existing implementations of these standards have limited the performance of some recent detector systems. This paper describes how the synchrotron light source community has worked closely with The HDF Group to drive changes to the HDF5 software to make it more suitable for their environment. This includes developments managed by a detector manufacturer (Dectris - for direct chunk writes) as well as synchrotrons (DESY, ESRF and Diamond - for pluggable filters, Single Writer/Multiple Reader and Virtual Data Sets).
