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.

| WEPL029 | Applicability of XAL for ESS | 85 |

| XAL is a Java based application framework, developed at the Spallation Neutron Source (SNS). The framework is designed to provide an accelerator physics programming interface to the accelerator and it allows writing general purpose applications dedicated to various parts of the accelerator. The backbone of XAL framework is an XML based description of the accelerator. The XML file provides the list of all devices, their properties, and in-between devices relations within the system. Since the accelerator structure is defined in the relational database, the XML can be generated directly out from the database using appropriate adapters. This allows the framework to be more generic and enables it to run on different sites using various configurations. The generality of the XAL and the rich set of applications and tools provided by SNS make the framework very appealing for usage at other accelerator sites. European Spallation Source (ESS) is being built in Sweden, which will be in overall an accelerator similar to SNS. Therefore, XAL has been considered to be used at ESS for high-level applications. The applicability of XAL and prototyping for ESS will be discussed in this article. | ||
