The X-ray Free-Electron Laser (XFEL) is a new accelerator currently under construction at DESY. It will be a powerful X-ray source for many scientific disciplines ranging from physics, chemistry, and biology to material sciences, geophysics, and medical diagnostics. The commissioning is planned in 2014, and the preparation of the control system was started. The XFEL makes high demands on the control system and its user interface. For this reason jddd, a new Java Data Display program for the Distributed Object-Oriented Control System (DOOCS), has been developed. jddd is a graphical editor for designing and running control panels. The editors functionality is similar to standard IDEs like NetBeans or Eclipse. Complex control panels can easily be created without programming. jddd offers all components needed for control panel design. The Components are reusable Java Beans like labels, buttons, plots, and complex dynamic components as Switches. The jddd panel structure is stored in an xml format. jddd is a further development of the DOOCS data display (ddd) program. For compatibility reasons the old ddd storage format can be converted to the new jddd xml format.

The device control in the LHC experiments is based on OPC servers and PVSS SCADA systems. A software framework enables the user to set up his PVSS project for the different devices used. To achieve a homogeneous operational environment for the ALICE experiment, these devices need to be controlled thought standard interfaces. PVSS panels act as the upper control layer and should allow for full control of the devices. The PVSS object-oriented feature has allowed the development of device Object Libraries. The Object Libraries have two main advantages. On one hand, they ease the operator task thanks to the introduced standardization of the various device control panels. On the other hand, they reduce the developer’s job as only basic software knowledge is required to set up a control application for a standard device. This paper will describe the device control architecture including PVSS, software framework, and OPC server. It will describe the Object Libraries developed for some devices, and it will explain how the Object Libraries integrate tools in the ALICE controls environment, such as Finite State Machines, access control, and trending.

A new PLC-based beam-charge interlock system is under development for radiation safety at the KEKB injector linac. This system restricts a prescribed amount of integrated beam charges passing through at several locations along the linac for machine protection, and it also monitors the amount of integrated beam charges injecting to four different storage rings (KEKB e+ & e- storage rings, PF, PF-AR) at the linac beam switchyard. The beam charges delivered from an electron gun are measured with the PLC-based beam-charge interlock system. This system comprises wall-current monitors, beam-charge integration circuits, and a PLC-based control system. This system generates and sends beam abort signals directly to another radiation safety control system with hard-wire cables when the amount of the integrated beam charges is beyond the prescribed threshold level. In this report we describe the new design of the PLC-based beam-charge interlock system, and especially several software developments and performances implemented on the PLC are described.

The control system for the Energy Recovery Linac Prototype (ERLP) under construction at Daresbury uses EPICS and vxWorks on VME64x. The client software in use during the commissioning of the accelerator is based on PC consoles running Red Hat 9. Synoptic displays and engineering panels are created using the Extensible Display Manager (EDM) and other standard EPICS extension software is used for archival and alarm handling. The Synchrotron Radiation Source (SRS) control system uses a bespoke control system with client software on PC consoles running Microsoft Windows. We would like to employ a similar approach for the operational client software on ERLP with Channel Access clients running on Microsoft Windows PC consoles. However, the Microsoft Visual Studio development tools and ActiveX/COM technologies used for creating client side software on the SRS control system are now outdated and have been superseded by the .NET framework and associated developer tools. This paper discusses the different options currently available for developing Channel Access clients on the Microsoft Windows platform, along with progress in creating Channel Access clients for the .NET framework.

Redundant EPICS IOC is being actively developed at DESY in order to achieve high availability. Current development focuses on VME vxWorks environment for cryogenics controls. However, many facilities use PC-architecture and unix-like systems as Linux and FreeBSD. These facilities require high availability and redundancy as well. So this paper will describe the implementation of EPICS redundant IOC in PC-based environment with Linux and FreeBSD. This work will be done by porting Redundancy Monitor Task (RMT) and Continuous Control Executive (CCE). RMT is responsible to make a decision when to fail-over; it is rather independent and may be used in a wide range of applications. In the future it can be employed in caGateway to add redundancy. CCE is aimed to synchronize two RSRV-based IOC servers.

The ALICE experiment at the LHC incorporates a transition radiation detector (TRD) designed to provide electron identification in the central barrel at momenta in excess of 2 GeV/c as well as fast (6 us) triggering capability for high transverse momentum (pt > 3 GeV/c) processes. It consists of 540 gas detectors and about 1.2 million electronics readout channels that are digitized during the 2 us drift time by the front-end electronics (FEEs) designed in full custom for on-detector operation. The TRD detector control system (DCS) back end is fully implemented as a detector-oriented hierarchy of objects behaving as finite state machines (FSMs). PVSS II is used as the SCADA system. The front-end part is composed of a 3-layer software architecture with a distributed information management (DIM) server running on an embedded Linux on-detector system pool (about 550 servers) and the so-called InterComLayer interfacing the DIM client in PVSS as well as the configuration database. The DCS also monitors and controls several hundreds of low- and high-voltage channels, among many other parameters. The layout of the system and status on installation and commissioning are presented.

The successful achievement of many physics goals of the CMS experiment required the design of an electromagnetic calorimeter (ECAL) with an excellent energy and angular resolution. The choice of the scintillating crystals, photodetectors, and front-end readout electronics of the ECAL has been made according to these criteria. However, certain characteristics of the chosen components imposed challenging constraints on the design of the ECAL, such as the need for rigorous temperature and high voltage stability. For this reason an ECAL Detector Control System (DCS) had to be carefully designed. In this presentation we describe the main DCS design objectives, the detailed specifications, and the final layout of the system. Emphasis is put on the system implementation and its specifc hardware and software solutions. The latest results from final system prototype tests in the 2006 ECAL test-beam program, as well as the system installation and commissioning at the CMS experimental construction site, are also discussed.

The LHC cryogenics control system is based on the CERN Industrial framework UNICOS (Unified Industrial Control System). UNICOS covers aspects related to both the SCADA (Supervisory Control and Data Acquisition) and the PLCs (Programmable Logic Controllers). The LHC cryogenic instrumentation must deal with the hostile radiation environment present in the accelerator tunnel preventing the use of off-the-shelves sensor signal conditioners. The conditioners are then realized with rad hard components connected to the control system through a WordlFIP fieldbus. A custom application using a FESA (Front-End Software Architecture) framework has been developed in an industrial PC, the standard CERN solution for WorldFIP interfacing. The solution adopted is based on custom generators that allow rapid prototyping of the control system by minimizing the human intervention at the configuration time and ensuring an error-free application deployment. This document depicts the control system architecture, the usage of custom generators within large systems, and the integration of the software applications with a classical industrial controls architecture application.

In the upgrade project of Beijing Electron Positron Collider (BEPC)II, a novel DCS(Detector Control System) for the Beijing Spectrometer (BES)III is developed. In the system, nearly 7000 data points covering dozens of physical parameters need monitoring or control. The upper system is mainly developed by LabVIEW and OPC. The lower system mainly used Embedded system, MCU, and PLC, etc. These technologies reduced the cost greatly without any lose in system functions or performance. This paper will give a detailed introduction to the system architecture and advanced technologies we used or invented.

The CLIC Test Facility 3 (CTF3) is an R&D machine being built to validate concepts that will be used for the Compact Linear Collider (CLIC). Because CTF3 is an instrumentation-intensive machine, a considerable amount of money is put into the acquisition hardware and high-quality cables used to bring the instrument signals to the digitalization crates with as little degradation as possible. The main idea of this new approach is to reduce the distance between the signal source and the A/D conversion, reducing the cost of the cabling. To achieve that, we have developed a radiation hard front-end that we install directly into the accelerator tunnel. This front-end deals with the digitalization of the signals after an analog buffering. Afterwards, the data are sent to a computer through the SPECS field bus. Finally, the digitalized signals are made available to the operation crew thanks to a server implementing the OASIS (Open Analogue Signal Information System) interfaces in the CERN Front-End Software Architecture (FESA). After a presentation of this low-cost solution to BPM acquisition, the paper gives the results of the first integration tests performed in the CTF3 machine.

We developed a logic-reconfigurable VME board with high flexibility. The board has two parts, a base board and two IO daughter boards. The base board has a field programmable gate arrays (FPGA) chip for execution of user logic, such as a digital low-pass filter or calculation of the median of a spot image. Users can install their logics into the FPGA via VME bus. The IO daughter boards are simple IO modules such as analog inputs/outputs (AIOs) or digital inputs/outputs (DIOs). The data from the IO board is sent to the base board and processed there. As the IO daughter board is separated physically, the user can customize the VME board by choosing daughter boards and does not need to develop whole device. We have developed DIO, AIO, and Camera Link interface as the IO daughter board. In the presentation, design concept and implementation of this VME board are shown with some applications.

Motion control solutions for controlling a movement of motorized mechanical subsystems for accelerators, telescopes or similar spatially distributed systems require high degree of flexibility regarding the use and connectivity. One platform should fit different applications and provide cost effective solutions. A connection to the control system (CS) is required on one side, while on the other side a connection to a variety of motors, position encoders and other feedback devices must be provided. In case of more complex mechanics, an advanced kinematics control is essential to provide features such as motion tuning, interpolation and controlled acceleration. An embedded computer is used for SW-flexibility and CS-support. Motion control capabilities are provided by separate HW; programmable multi axis controller. Signal adaptation for a direct connection of the equipment is managed by an interface board. Easy installation and debugging is provided by low-level local control; front panel switches and indicators, RS232 or direct keyboard and monitor access. An advanced approach is required in case of a larger distance between the motor controller and the motors with position encoders.

Over the past several years, a variety of imaging systems have been deployed at Oak Ridge National Laboratory's (ORNL's) Spallation Neutron Source (SNS). The systems have supported accelerator instrumentation, neutron beam measurement, target commissioning, and laser diagnostics. For each application, performance requirements drove the choice of camera technology, and this naturally led to a variety of interfaces. This paper will describe the experience gained during the integration and operation of these systems. Several challenges will be highlighted, including algorithms for quantitative measurements, correlation with other accelerator data, real-time video distribution, and storage of large data sets. Although heterogeneous systems must continue to be deployed to meet imaging needs, some common tools and technologies have been identified and are expected to enhance system integration efforts.
