WEPL021	Soft real-time control with client/server control system	controls, 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.

THCOMA02	synApps: EPICS-Application Software for Synchrotron Beamlines and Laboratories	photon, controls, diagnostics, feedback	106
	T. Mooney ANL, Argonne
	synApps is a collection of EPICS-application software originally intended to support the needs of scientists working at synchrotron-radiation beamlines. The collection contains general purpose software that extends or exploits capabilities of EPICS base, and a large amount of instrument-specific software that applies EPICS to control and provide a user interface for off-the-shelf electronics. This presentation will provide an overview of synApps, describe how synApps is deployed at the Advanced Photon Source, and highlight recent additions to the collection.

THCOMA03	Using ezcaIDL to connect to EPICS Channel Access from SHADOWVUI for Dynamic X-ray Tracing	simulation, optics, 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).

THPL006	Mechanical Vibration Measurement System at the Canadian Light Source	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.

THPL015	Macro package based Enhancement of SPEC controlled Experimental Setups	controls, vacuum, 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.

THPL022	Plans for monitoring TPS control system infrastructure using SNMP and EPICS	controls, monitoring, power-supply, synchrotron	174
	Y.-T. Chang, J. Chen, Y. K. Chen, Y.-S. Cheng, K. T. Hsu, K. H. Hu, C. H. Kuo, C.-J. Wang, C. Y. Wu NSRRC, Hsinchu
	The Taiwan Photon Source (TPS) control system is one of the crucial systems for the accelerators and beamlines. It is necessary to monitor the status of the control system components such as housekeeping parameters of cPCI EPICS IOC crates, network traffic, connections between computers, etc. The equipment room environment including electric power, temperature, fire alarm, and water leak will also need to be watched. Using Simple Network Management Protocol (SNMP), the behaviour of network-attached devices can be monitored for administrative attention. Since the TPS control system is based upon the EPICS framework, the monitoring system is planned to adopt the EPICS support with SNMP. This paper will describe the system architecture of this monitoring system.
