| WEPL028 | TINE/ACOP state-of-the-art Video Controls at Petra III | background, controls, diagnostics, electron | 82 | |||||
|
The TINE/ACOP video system is a complete state-of-the-art solution for streaming beam video, featuring live analysis and live beam image display inside ACOP video component, which can be placed in any Java Swing panel. After a number of iterative improvements and embellishments, the system has matured to stable production quality in the beginning of year 2010. The system consists of the following components: a TINE device server captures a video image [1] and encodes it to the standard TINE IMAGE format. The TINE transport layer streams the IMAGE objects to clients as it would any other data chunk [2]. The Java TINE client passes the IMAGE object through the analysis Java bean, which then performs fast statistical analysis of beam position and size. The streamed image plus analysis data are displayed in the Java video component, which is part of the ACOP components. Additional capabilities are background subtraction, automatic or manual threshold subtraction, enhanced coloring and saving snapshot as PNG file. Optionally, the analysis bean can be used standalone as a common service and results are further distributed via an intermediate TINE server written in Java.

| WEPL035 | High Level Matlab Applications for SPEAR3 | controls, simulation, diagnostics, synchrotron | 97 | |||||
|
The SPEAR3 control system nominally operates with the EPICS control system toolbox operating on VMS hardware. The simultaneous use of Matlab Middlelayer (MML) and Accelerator Toolbox (AT) allow for parallel, high-level machine control and accelerator physics applications that communicate with the control system via EPICS Channel Access (LabCA). While the majority of MML and AT software is machine-independent, site-specific applications are required to control most accelerators. This paper describes several such high-level application programs that have been developed for diagnostics and control of SPEAR3. Examples include interlock verification software, transport line optics and steering applications, optical diagnostics, add-ons to main MML routines and time-dependent waveform display.

| FRCOMA03 | Beam Profile Monitoring System for XFEL/SPring-8 | controls, monitoring, diagnostics, beam-transport | 198 | |||||
|
XFEL/SPring-8 will start beam commissioning in March 2011. Beam profile monitors are an important tool for beam diagnostics. The diagnostic tool monitors beam profile images and evaluates beam shapes and intensities in real time. Image data is stored with a beam tagged number to be compared with other synchronized data such as beam position monitors. Many functions are required to the diagnostic tool. The monitor system consists of screens and CCD cameras with lens assemblies. The screens and lenses are controlled with programmable logic controllers. The cameras are connected to a PC with Camera Link. To choose a camera, selectors are used. On the PC, a server program writes image data into shared memory and a diagnostics tool fetches the data. The diagnostics tool is developed using Python with a graphical user interface (GUI) based on wxPython. In the GUI, several functions such as image analysis, camera control, data record and viewer are required, and easily implemented with the Python. The beam profile monitoring system was tested with the SCSS prototype accelerator under similar condition, and then will be applied to XFEL/SPring-8.
