WEPL009	Integration of Programmable Logic Controllers into the FAIR Control System using FESA	controls, ion, photon, antiproton	44
	R. Haseitl, C. A. Andre, H. Bräuning, T. Hoffmann, R. Lonsing GSI, Darmstadt
	For the upcoming 'Facility for Antiproton and Ion Research' (FAIR) at GSI, the Front End Software Architecture (FESA) framework built by CERN has been chosen to serve as front-end level of the future FAIR control system. All future beam diagnostic devices will be controlled by FESA classes that are addressable by the new control system. The connectivity to the old control system is retained, since both control systems will be in operation contemporaneously for several years. Commercially available Programmable Logic Controllers (PLCs) have been installed as part of beam induced fluorescence (BIF) monitors to replace outdated network attached devices and to improve the reliability of the BIF systems. The new PLC devices are now controlled by FESA classes which are addressed from the existing C++ software via RDA calls. This contribution describes the system setup and the involved software components to access the PLC hardware.

WEPL021	Soft real-time control with client/server control system	controls, synchrotron, synchrotron-radiation, scattering	70
	Y. Furukawa JASRI/SPring-8, Hyogo-ken
	Real-time properties has studied for client/server control system on single cpu control system with Linux and Solaris operating system (OS) with real-time scheduler. Time jitters were with in one msec for Linux OS (CPU was 1.5GHz pentium-M) and a few msec for Solaris OS (CPU was 800MHz Pentium-III) on the MADOCA control sysmtem which is the SPring-8 standard controls system. These results are small enough for may synchrotron radiation experiments such as x-ray diffraction experiments with continuous scanning method. The client application can be described using scripting languages, so real-time applications developed and modified easily. The system has been used in the diffuse scattering beamline at the SPring-8.

WEPL023	Improvements for Simple Operation at SAGA-LS Accelerator	controls, injection, linac, acceleration	76
	Y. Iwasaki, T. Kaneyasu, S. Koda, Y. Takabayashi SAGA, Tosu
	The SAGA Light Source (SAGA-LS) is a medium size synchrotron light facility, which consists of a 255 MeV injector linac and a 1.4 GeV storage ring. The control system of the accelerator has been constructed and developed from the beginning of the machine commissioning. We have employed PC-based control system because of a high cost performance of PC. The Channel Access protocol is emulated using ActiveX CA to communicate with server PCs and client PCs. Off-the-shelf industrial IO devices such as FieldPoint, and PLC are directly connected to the local server PC (PC-IOC) via Ethernet. The applications for the system are developed in-house using LabView. Recently, for plain and easy operation of accelerator we have made several upgrading of the control system. First, we made communication interfaces between accelerator system and radiation interlock system. Second, we attempt to reduce the number of server machines as possible as possible. Third, we develop a PC client program, which communicates with server PCs by a sequential procedure and sets the radiation interlock mode using touch panel PC display. By these improvements the daily operation of accelerator has become simplified.

THCOMA03	Using ezcaIDL to connect to EPICS Channel Access from SHADOWVUI for Dynamic X-ray Tracing	simulation, optics, synchrotron, synchrotron-radiation	109
	A. M. Duffy CLS, Saskatoon, Saskatchewan
	Using the ezcaIDL library, for IDL, to provide an interface to EPICS Channel Access through the EZCA library, a simple XOP* extension was written that initializes ezcaIDL and thus allows access to a set of simplified IDL interface commands to connect to Channel Access from within XOP and also from SHADOWVUI. The XOP widget-based driver program is a commonly used front-end interface for computer codes of interest to the synchrotron radiation community. It models x-ray sources and characterizes optics. Extensions, such as SHADOWVUI, are optionally loaded to easily expand its functionality. An essential tool for x-ray optics calculations is the ray-tracing program SHADOW**. A complete Visual User Interface for SHADOW (SHADOWVUI) is an interactive tool for designing an optical system and visualizing results as graphs, histograms. The working scheme is to define the source and the optical elements by entering parameters. The author has taken the usual SHADOWVUI simulation of an x-ray system a step further by using ezcaIDL to interface with the EPICS control system to access the positions of optical components in real life and then run a corresponding simulation based upon these. Interactive Data Language. X-ray Oriented Programs. * SHADOW was developed at Nanotech-Wisconsin (University of Wisconsin).

THCOAA02	Remote Access to the VESPERS Beamline using Science Studio	controls, synchrotron, monitoring	118
	D. G. Maxwell, D. Liu, E. Matias, D. Medrano CLS, Saskatoon, Saskatchewan M. Bauer, M. Fuller, S. McIntryre, J. Qin UWO, London, Ontario
	Science Studio is a web portal, and framework, that provides scientists with a platform to collaborate in distributed teams on research projects, and to remotely access the resources of research facilities located across Canada. The primary application for Science Studio is to provide scientists with remote access to the VESPERS beamline at the Canadian Light Source synchrotron in Saskatoon Saskatchewan, and to readily process data from this beamline at the SHARCNET high performance computing facility in London Ontario. The VESPERS beamline is a complex instrument that is composed of many devices, such as valves, motors and detectors, which are all controlled through the low-level EPICS control system. Science Studio implements a simple, intuitive and functional web-based interface to the beamline for device control and data acquisition. The Science Studio experiment management system allows the acquired data to be easily organized and shared with the research team. This paper will provide an overview of the design, implementation and capabilities of the Science Studio system, with a focus on remote control of the VESPERS beamline.

THPL006	Mechanical Vibration Measurement System at the Canadian Light Source	synchrotron, synchrotron-radiation, damping, optics	133
	J. Li, X. B. Chen, E. Matias, W. Zhang CLS, Saskatoon, Saskatchewan
	In recent decades, synchrotron radiation has developed into an invaluable scientific tool around the world. At synchrotron radiation facilities, the mechanical vibrations in the optics hutch and experimental hutch, especially in the vertical direction, enlarges the beam size and changes intensity of the monochromatic X-ray beam. To investigate mechanical vibrations at the CLS, a vibration measurement system was developed. The system includes a Vector Signal Analyzer (VSA) and accelerometers. The sensitivity of the accelerometer is 1.02 v/(m/s2). The frequency range of the accelerometer is 0.1 Hz to 300 Hz. The frequency resolution of the accelerometer is better than 0.1 Hz. The vibrations at four beamlines and endstations at the CLS, i.e. the Canadian Macromolecular Crystallography Facility (CMCF) 08ID-1 beamline, the Hard X-ray MicroAnalysis (HXMA) 06ID-1 beamline, the Resonant Elastic and Inelastic Soft X-ray Scattering (REIXS) 10ID-2 beamline, and the Scanning Transmission X-ray Microscope (STXM) endstation at the Spectromicroscopy (SM) 10ID-1 beamline, are investigated.

	V. Ayvazyan, Z. Geng, M. K. Grecki, O. Hensler, M. G. Hoffmann, M. Hoffmann, T. Jezynski, W. Koprek, F. Ludwig, K. Rehlich, H. Schlarb, Ch. Schmidt, S. Simrock, H. C. Weddig DESY, Hamburg K. Czuba Warsaw University of Technology, Institute of Electronic Systems, Warsaw
	The Free Electron Laser in Hamburg (FLASH) is a user facility providing high brilliant laser light for experiments. It is also a unique facility for testing the superconducting accelerator technology for the European XFEL and the International Linear Collider. As a test facility, the accelerator undergoes a constant modification and expansion. The recent upgrade started in autumn 2009. The beam energy is increased to 1.2 GeV by installing a 7th superconducting accelerating module. The new module is a prototype for the European XFEL. In order to increase the FEL radiation intensity by linearization of the beam phase space the 3rd harmonic superconducting RF cavities are installed in the injector. LLRF control system has been completely upgraded to latest generation controller boards, down-converters for higher intermediate frequency, algorithms improved like beam loading compensation, feed-forward waveform generation, etc. In order to improve the reference frequency signals the master oscillator and frequency distribution system has been upgraded as well. The paper summarizes the recently finished LLRF system upgrade and expected RF field control performance at FLASH.

THPL015	Macro package based Enhancement of SPEC controlled Experimental Setups	controls, vacuum, synchrotron, synchrotron-radiation	159
	T. Spangenberg, K. Cerff, W. Mexner Karlsruhe Institute of Technology (KIT), Karlsruhe
	Certified Scientific Software's program package spec for X-Ray diffraction and data acquisition provides reliable instrument control to scientists at synchrotrons and other facilities worldwide. It’s very flexible C-like macro language provides a large number of degrees of freedom for experiment control as advantage and as big disadvantage at the same time. A large number of programmers with their own ideas and naming conventions are contributing to the growth of functionality. At the same time the risk of collateral damage by accidentally overriding already existing functions and variables grows constantly. To solve this dilemma a new object oriented like software development concept for spec is proposed. A few naming rules plus a macro package in combination with a single client-server-application expand the manageability and options to control experiments considerably. As main goal spec gets an object-like handling and a standardized user interface of newly introduced devices. A generic server-client based interface allows a smooth integration of spec in more complex control environments via TANGO.

	G. H. Gong, T. Xue Tsinghua University, Beijing
	The industrial CT is used to generate a 3D image of the inside of an object, it consists of an accelerator x-ray source, a detector array and readout electronics. A trigger module collects the position information from three decoders installed all the 3 moving axis of rotation, shift and lift, and generates trigger signal according to the predefined trigger algorithm; the decoder information is also sent to the readout electronics. The SCS (system control station) can remotely communicate with trigger module to change the working modes and parameters during the scan process. The trigger module utilizes an embedded controller board which consists of a PowerPC controller running the Linux operation system to support the TCP socket connection with SCS, and a FPGA connected to the PowerPC local bus acts as a customized peripheral to carry out the trigger logic. With different interface mezzanines and online reloadable firmware, the trigger module has great flexibility to work with different decoders, different readout electronics.
