WIRED - World Wide Web interactive remote event display

WIRED (http://wired.cern.ch/) is a framework, written in Java, to build Hig h Energy Physics event displays that can be used across the network. To gua rantee portability across all platforms, WIRED is implemented in the Java l anguage and uses the Swing user interface component set. It can be used as a stand-alone application or as an applet inside a WWW browser. The graphical user interface allows for multiple views and for multiple con trols acting on those views. A detector tree control is available to toggle the visibility of parts of the events and detector geometry, XML (Extensib le Markup Language), RMI (Remote Method Invocation) and CORBA loaders can b e used to load event data as well as geometry data, and to connect to FORTR AN, C, C++ and Java reconstruction programs. Non-linear and non-Cartesian p rojections (e.g., fisheye, rho-phi, rho -Z, phi -Z) provide special views t o get a better understanding of events. A special Java interpreter allows p hysicists to write small scripts to interact with their data and its displa y. WIRED has grown to be a framework in use and under development in several H EP experiments., (ATLAS, CHORUS, DELPHI, LHCb, BaBar, DO and ZEUS). WIRED e vent displays have also proven to be useful to explain High Energy Physics to the general public. Both CERN, in its traveling exhibition and MicroCosm . and RAL, during its open days, have displays set up. (C) 2001 Elsevier Sc ience B.V. All rights reserved.
