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.

We describe the control system operation for the new injector project built at the Laboratori Nazionali di Frascati INFN (SPARC). The injector started the operation in the autumn of the 2007 and the control systems has been full operating since the start of commissioning and integrate all tools to help the machine operation. The SPARC control system must follow all evolution in the continuous machine installation and evolution. To allow us a rapid develop in the control system we have made some choice in its development: Labview as developing system due to its diffusion in the laboratory and it become standard in the acquisition software; Gigabit Ethernet as interconnection bus this choice give the sufficient bandwidth in the data exchange; PC as front-end CPU and operator console this kind of machine give the sufficient computing power. We develop all control application for magnetic elements, vacuum equipment, RF cavity, all diagnostics, laser and some experimental apparatus have been developed and debugged on line. We developed an automatic process to store all the element information in two ways periodic and on data change.

The new PostgreSQL database is developed for systematization and unification of the data archiving and observation at the VEPP-4 facility. About three thousands parameters are set and checked for the VEPP-4 control. The current values are read from the control and measuring electronics and stored into the many files with different time of storing. The storing intervals vary from one second for the pulse systems to several minutes for the slowly changing parameters. Parameters are transfer to the database as soon as they are renewed in the source files. Twelve independent processes running under Linux provide the permanent data transfer from the files with current values to the database. The graphical interface is developed for user’s access to the database. It provides observation of the stored data in graphical or textual form and monitoring of the current parameter values. The interface allows us to observe any collection of parameters in a single or in different windows for any period of time.

The control system of the synchrotron radiation source ANKA at Forschungszentrum Karlsruhe was segmented into several autonomous parts. The storage ring have been controlled by the ACS control system, the infrastructure facilities by the supervisory control and data acquisition system (SCADA) named IGSS, and several autonomous PLC based interlock systems for the accelerators and beam lines. Each system required special knowledge for maintenance and failure diagnostics. In order to improve the manageability and to reduce cost, the SCADA system PVSS II has been chosen as a supervisory control system, integrating each of the individual parts. As the interface is open and easy to handle the integration was straightforward. The majority of the existing control systems have been integrated with limited man power during a one year period followed by a continuous optimization process. The new system with a common look and feel for beam lines and machine was quickly accepted by beam line scientists, technicians and operators.

The technical challenge in many physics experiments is to capture and process images. There are many solutions in this domain. One which seems to be cost effective with high performance, refers to firewire cameras. This type of cameras are easily connected with the PCs by mean of the firewire bus. We present a concrete solution about firewire cameras' integration into the EPICS control system. Our solution allows for image capturing, processing and image distribution using Channel Access and HTTP protocols.

TINE Video System – A Modular, Well-defined, Component-based and Interoperable TV System Undergoing a Redesign

DESY Zeuthen, Zeuthen

In recent years, the usage of TV systems and optical readout at accelerator facilities has constantly been increasing. At the same time, the pace of vendor upgrades of industrial vision hardware has hardly slackened. Because image readout hardware is required to meet special criteria in accelerator physics, vastly different hardware systems are frequently used side by side. Given such circumstances it is not surprising that the imaging software needs to be changed, adapted and updated on a semi-permanent basis. Current TV systems cannot cope very well with rapid software and hardware changes. To improve this, a redesign of the current TINE Video System*, initiated at PITZ, was undertaken. Efforts are focused on an abstract, modular grabbing interface, dedicated software components, a well-defined Video Transport Layer and use of standard file formats where possible. This paper will show current, planned and possible software architectures as well as hardware support and outlines perspectives for near and far future. Although the current implementation is integrated into TINE control system, it is modular enough so that integration into other control systems can be considered.

One of the strengths of the TINE* control system is the ability to easily make ‘rich-client’ applications containing that programming and display logic which is designed to expedite and enhance the operator’s or physicist’s abilities to diagnose problems and correlate results. In particular there are a large number of ‘rich-client’, general purpose applications which offer extensive interactions with the TINE standard servers and subsystems. This includes the TINE archive system, alarm system, post-mortem system, and video system, as well as scope trace analysis, multi-channel analysis and general configuration management. Available now for many years, these diagnostic applications have recently been realized as pure java applications using ACOP** beans. All applications have been honed and refined based on extensive feedback from the application users. We offer here a description of these applications, some of the novel techniques used and focus on those ‘rich-client’ aspects which cannot be achieved by configuring ‘simple-clients’ based on displayer widgets.

AS-Interface according to IEC 62026-2 is a simple low level field bus system that is well established in industrial automation. It is designed for the easy connection of simple sensors and actuators like switches or valves and can be seen as a low level complement to primary fieldbus systems like PROFIBUS or DeviceNet. Although it is a well established and proven industrial technology, it is rarely seen in research application. In order to simplify cabling and improve overall diagnostics, Forschungszentrum Jülich introduced AS-Interface into the control system of the small angle neutron scattering experiment KWS1. The paper gives an overview of the AS-I technology. The control system of KWS1 and experiences with AS-I are presented.

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.

A comprehensive C++ framework, using the HTTP-based 'black box' protocol, has been developed to allow PC-based control, data acquisition and data visualisation of new JET diagnostic enhancements. This framework allows remote and local developers to develop new applications, with extensive code re-use, without needing to re-implement exiting communication, data management or data visualisation functionality. The paper describes the usage of the Windows implementation. The paper also highlights 5 years of experiences in collaborative development using this approach, and details some of the lessons that have been learnt. The 'black box' approach at JET is similar to that proposed for the ITER plant systems delivered in-kind along with their I&C. Extensions to the framework to cater for the ITER model will be proposed.

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 interlock system prevents any damage from the cost expensive components of the RF station. The system monitors various system components, computes the status in-formation in realtime and reports actual status to the control system. The system is designed for maximum reliability and max. time of operation. It includes self diagnostic and modular repair strategies. The interlock incorporates a controller and slave modules that perform the I/O opera-tion. They are connected to distribution panels that supply flexible interfaces to exter-nal components. The interlock logic is implemented in hardware and operates independ from the proc-essor and the software. The software accomplishes the hardware selftest on system startup. Further applications provide communication interfaces over Ethernet used by administration and the controlsystem. A runtime software integrity selftest strategy has been implemented for high reliability. It covers detection of stack overflows, thread deadlocks, memory corruption and is able to recover the system without inter-rupting interlock operation. The interlock system performs well its task at FLASH (DESY, Hamburg Site) and at PITZ (DESY, Zeuthen Site).

At XFEL it is planned to install most electronic components and computers for LLRF, diagnostics and controls inside the tunnel. Access to these devices during the XFEL operation will not be possible. Remote control and monitoring of all relevant parameters of the shelfs/crates and the computers must be ensured and should be done in a standardised way. In addition software downloads and debugging up to the FPGA level should be provided, even if an operating system crashes e.g. due to radiation, maintenance functionality must be available. An introduction to xTCA will be given, the reasons to change the crate standard from a VME to a xTCA based system and the experience with this new electronics standard will be described.

The HIT ACS is a modular, PC and front-end controller (with FPGAs) based accelerator control system developed by the company Eckelmann AG, Wiesbaden, Germany in cooperation with GSI and HIT. It consists of a database and several central applications running on Windows 2k3 server machines as well as a dozen control room client PCs for the GUIs, and a few hundred front-end device controlling units (DCUs). Due to strict timing requirements in the ms and partly μs range, communications during an acceleration cycle are done in real-time via RTB (Real Time Bus) and real-time shared memory components on the main control server. We show the overall structure of the ACS network and outline the relation of the component devices and the Ethernet and RTB communications between them.

The Heidelberg Ion Therapy Center HIT is presently in the final phase of commissioning. HIT consists of a two-stage linac followed by a compact heavy-ion synchrotron. The ion beam can be delivered to two horizontal treatment places and a gantry structure for 360° patient treatment. In this contribution we report on the basic concepts for the integration of the beam diagnostic data acquisition into the overall accelerator control system and the distributed timing devices. The equipment-side abstraction layer of facility-wide device classes and its seamless integration besides device control units, e.g. for power supplies, is presented and first operational experiences of the machine commissioning are discussed. As examples for the data acquisition of the high-energy beam transport section the detection of beam profiles using MWPCs and Scintillation Screens is presented, as well as measurements of beam intensity using ionization chambers.

The planned Facility for Antiproton and Ion Research (FAIR) at GSI in Darmstadt is a very challenging task due to its dimension and complexity. Several new heavy ion accelerators have to be built and then operated in parallel and multiplexed modes. In order to cope with these unique requirements numerous collaboration partners are involved to add so-called ”in-kind contributions” to the project. Detailed guidelines and interface specifications have to be defined in advance to avoid an indefinite pool of different technologies which have to be handled by the future control system. For that purpose, GSI decided to use the Front-end Software Architecture (FESA) at the lowest level of the control system. FESA was developed by CERN and is already established for usage at LHC and its injectors. It is a framework to integrate any kind of equipment such as beam instrumentation devices, magnet power supplies, vacuum- and cryogenic components into the control system. A framework overview, its advantages, and boundary conditions provided by FESA are described.

Shortly before first tumour patients will be treated with high-energy ions at the facility in Heidelberg we give an overview of the control systems special characteristics, current status and remaining functionality to completion. The control system was designed by GSI but has been developed by an all-industrial partner. At each of the three therapy rooms more than 20000 combinations of beam energy, intensity and focus can be requested by the therapy control system. The commissioning for carbon and proton ion beams has already been conducted by GSI. We show how different operating conditions are implemented to ensure at the same time the possibility for experimental research while beam properties already verified within medical test procedures must not be altered without following predefined workflows. Therefore all system and device parameters as well as all set values that possibly change beam properties for patient treatment have to be securely locked or e.g. integrated into checksums. We will also focus on several minor and a few major changes in functionality that had to be implemented to conform to the requirements that originated by the risk assessment of the control system.
