MOX01	TINE Release 4 in Operation	controls, vacuum, diagnostics, power-supply	1
	P. Duval, P. K. Bartkiewicz, S. W. Herb, H. Wu DESY, Hamburg S. Weisse DESY Zeuthen, Zeuthen
	The TINE* control system evolved in great part to meet the needs of controlling a large accelerator the size of HERA, where not only the size of the machine was a determining criterion, but also the seamless integration of different platforms and programming languages of the many applications developers. In keeping pace with new technologies and the new generation of accelerators such as PETRA3, FLASH, PITZ and associated pre-accelerators and beamlines, TINE has undergone a major “face-lift” in its most recent version, 4.0.1, where platforms such as Java and LabView are not only supported, but emphasized. In addition, TINE Release 4 integrates the video subsystem, the device layer, and central services to a much greater extent than its predecessor. We report here on many of the new features and how they are currently being used in operations. * http://tine.desy.de

MOY03	Surveying Software Technology for Accelerator Control Systems	controls, storage-ring, survey, electron	16
	T. Friedrich, M. Törngren KTH/MD, Stockholm
	Virtually all accelerator based research facilities nowadays use a mixture of software libraries, tools, protocols and development techniques to address the facilities’ various control system requirements efficiently. Many of these technologies are open-source and shared between laboratories to various extents. Motivated by the planning of MAX-lab’s new light source project, the MAX IV facility, we have conducted a state-of-the-art survey of these technologies, which will serve as a knowledge base for upcoming design decisions. This paper provides a summary of the topics and conclusions of our survey. In this scope the survey compares software technologies with respect to user features (scientific analysis and operation requirements), quality requirements (integration, performance, services, reliability, security, safety), and other issues. Control system design goals are beneficial long-term effects on feature opportunities, software development and maintenance costs.

TUP010	Buffer Manager Implementation for the FLASH Data Aquisition System	controls, laser, diagnostics, monitoring	102
	V. Rybnikov, A. Aghababyan, G. Grygiel, O. Hensler, R. Kammering, L. M. Petrosyan, K. Rehlich DESY, Hamburg
	The Free Electron Laser in Hamburg (FLASH) at DESY is a user facility. It produces laser light of short wavelengths from the extreme ultraviolet down to soft X-rays. To study, monitor and document the machine performance and parameters and also to collect the results of the experiment measurements a fast data acquisition (DAQ) system has been developed. A shared memory based buffer manager is the heart of the system. It arranges collected data as events for every linac short. All events can be read by different consumers simultaneously. Linac feedback and monitoring processes as well as experiment middle layer servers are typical clients of the buffer manager. Any client can also generate its own data and insert it into the same event or produce its own one. The paper will focus on the detailed implementation of the buffer manager and its main features. The experience and the achieved performance will be covered as well.

TUP013	First Experiences with a Device Server Generator for Server Applications for PETRA III	controls, survey	108
	J. Wilgen DESY, Hamburg
	In recent control systems at DESY, a device server generator and framework is used for the production of device servers in the TINE/Java environment. The generator significantly simplifies development and provides a standardized architecture for device server programs. First experiences are reported.

TUP015	A Modbus/TCP-based Power Supply Interface	power-supply, controls, ion, quadrupole	113
	D. T. Touchard, C. H. Haquin GANIL, Caen
	The Spiral2 project is aiming to provide high intensity rare ion beams for nuclear physics experiments. It is based first on a primary beam driver accelerator consisting of a RFQ followed by a superconducting L. I.N. A.C., then a rare ion production process delivers the beam either to a low energy experimental area or to the existing Ganil facility. The EPICS software has been chosen as the basic framework to improve efficient collaboration between several research laboratories (CEA-IRFU, CNRS-IPHC, GANIL) which are designing the accelerator control system. The whole facility will integrate more than 600 power supplies used for the magnetic and high voltage equipment control of the accelerator. It has been decided to interface these power supplies through the MODBUS/TCP protocol, using Ethernet as a field bus. This paper introduces the EPICS software archetype set up to assess the practicability of such a solution and presents a first implantation for prototyping.

TUP018	Re-writing ALS Control Room Software in C#	controls, gun, beam-transport, electron	122
	H. Nishimura, G. J. Portmann, CA. Timossi, M. E. Urashka LBNL, Berkeley, California
	After years of R&D studies showing the value of migrating the operator interface applications to the .NET Framework, a small team has been formed to focus on re-writing all of the high-level control system software using the C# programming language for the Windows Vista based operator stations. We have currently upgraded several major programs with the goal of focusing on the injector system that was commissioned in 1991. We will present real examples, and discuss the technical issues of migrating to the .NET Framework in the context of the EPICS* client programming. The architectural issues will be presented in another paper. *Dalesio, et al.

	Control systems of modern accelerators, such as RIBF, KEKB and J-PARC, adopt many programmable Logic controllers (PLCs). They are supervised by Input/Output controllers (IOCs) of Experimental and Industrial Control System (EPICS) with being controlled and monitored through Ethernet connections. In this type of control system, the adoption of Ethernet as a field-bus reduces the work load for the development of device/driver support modules of EPICS. On the other hand, having controllers (PLCs) under yet another controllers (IOCs) doubles the work load for the implementation of the front-end software. In order to solve the problem, we developed an embedded EPICS on F3RP61-2L, a CPU module running Linux that can work with a base module and I/O modules for FA-M3 PLC. We found that the IOC program can run without any modifications on the CPU module. This paper describes the details of the embedded EPICS system and the application of the new type of IOC for the control systems in operation and under construction.

WEZ01	The TINE Common Device Interface in Operation	controls, diagnostics, background, power-supply	154
	P. Duval, H. Wu DESY, Hamburg U. R. Ristau EMBL, Hamburg
	The Common Device Interface (CDI)* is the primary device layer used in the TINE control system. It offers a generic, database-driven view of a server’s hardware, where a hardware address, irrespective of the underlying bus, simply appears as a named device, which is accessed via the TINE client API. To date, CDI-supported busses include several CAN implementations, RS232, TwinCat, Libera**, Siemens PLC, as well as the DESY in-house bus SEDAC. In this paper, we report on the latest features of CDI and more importantly on the first experiences of using CDI in operations, primarily in the PETRA3 pre-accelerator chain and in DC, Servo, and stepper motor control at the EMBL beamlines.

	The Spiral2 project consists of a new facility to provide high intensity rare ions beams. It is based on a primary beam driver accelerator (RFQ followed by a superconducting linac) and a rare ion production process delivering the beam either to a low energy experimental area or to the existing Ganil facility. From October this year, one ion source coupled with a first beam line section will be in test; then, the injector (ion and deuteron sources, RFQ) will be tested by the end of 2010 so the whole accelerator should be commissioned by the end of 2011; the first exotic beams being planned one year later. The accelerator control system design results from the collaboration between several institutes and Epics has been chosen as the basic framework. The paper therefore presents the main choices: MVME5500 CPUs, VME I/O boards, VxWorks, Siemens PLCs, Modbus field buses, EDM screens and Java applications, Linux PCs, use of a LabView/Epics gateway<br/>Specific topics are the evaluation of the XAL environment, an Epics design to address the power supplies, an emittance measurement system, the development of a beam profiler interface and the investigation for a triggered acquisition system.

WEP006	BeamView - A Data Acquisition System for Optical Beam Instrumentation	controls, instrumentation, ion, radiation	180
	R. Haseitl, C. A. Andre, F. Becker, P. Forck GSI, Darmstadt
	At the GSI accelerator facility, several optical beam instrumentation devices for transversal profile measurement are installed. Their readout is done with FireWire CCD cameras attached to a small embedded device, specialized for image processing tasks (National Instruments Compact Vision System 1456). Here a LabView application preprocesses the images based on user requests. The resulting data (e.g. projections, histograms, compressed or original images) is sent over ethernet to a Windows or Linux PC, reaching frame rates above 30fps at VGA resolution. Using C++ with Qt libraries for networking and GUI purposes, platform independence without source code modification is achieved. In this paper we present the system components and software design to control CCD cameras and various other devices with an easy-to-use graphical user interface for machine operators.

WEP016	MicroIOC LR-BPM - Beam Position Monitor Solution	controls, pick-up, instrumentation, monitoring	204
	P. Medvešček, M. Kobal Cosylab, Ljubljana S. Artinian, J. F. Bergoz BERGOZ Instrumentation, Saint Genis Pouilly
	MicroIOC LR-BPM product offers complete beam position monitoring solution to be used on transfer lines or linear accelerators where bunch repetition rate is low (< 50Hz). It consists of Log ratio Beam position monitor (LR-BPM) modules from Bergoz instrumentation and of microIOC analog to digital acquisition unit (microIOC-ADA) from Cosylab. In this paper we present the detailed operation of the system and the results from testing that was performed at Soleil accelerator in May 2008. In this particular test microIOC LR-BPM proved to be a complete stand alone solution with only signals from the beam pickup detectors as inputs. It is capable of providing up to 8 X-Y beam positions and since its design is based on a single board computer inside the ADA unit it is easily integrated in a higher level control system software. Furthermore the position data is available to the control system clients over the external network via Ethernet link. EPICS was used as a control system although the product can accommodate other types of control systems that can run on x86 platform.

THX03	TCP/IP Vulnerabilities of Embedded-System Implementations	controls, storage-ring, monitoring, synchrotron	224
	T. Sugimoto, M. Ishii, T. Masuda, T. Ohata, T. Sakamoto, R. T. Tanaka JASRI/SPring-8, Hyogo-ken
	TCP/IP is established as a de facto standard network-communication protocol. Development of the TCP/IP enables us to build a large-scale distributed control system. Recent accelerator-control system consists of many TCP/IP devices; not only computers, but also embedded devices such as digital multimeters, oscilloscopes, multi-channel analyzers, and so on. Since these embedded devices are designed with limited hardware resources, most devices use subset of the TCP/IP components. The limited resources and components therefore cause many problems such as vulnerabilities of TCP/IP implementations. In SPring–8, by increasing the number of network-connected instruments with latent vulnerabilities, more trouble have arisen such as packet flooding and unexpected response delaying. One of the most serious trouble is hang-up of pulse-motor controllers* based on embedded operating system. To determine cause of the trouble, network-connected instruments were inspected using basic TCP/IP tools and security scanners. As a result, we successfully found vulnerabilities of embedded implementation. In this presentation, the cause of vulnerabilities in embedded systems will be discussed. * T.
