TOAB05 The Status of Virgo 71
  • F. Carbognani
    EGO, Pisa
  Virgo is the largest gravitational wave detector in Europe. The detector, built by a French–Italian collaboration, is located near Pisa (Italy) and is based on a laser interferometer with 3-km-long arms. It aims at the detection of gravitational waves emitted by galactic and extragalactic sources such as pulsars, supernovae, and the coalescences of binary black holes and neutron stars in a frequency window comprised between 10 Hz and a few kHz. Since 2003 the detector has been going through its commissioning phase, and the first long observing run is planned to start in May 2007. The present status of the experiment and its foreseen upgrades are described in this article.

Franco Carbognani is the corresponding author on behalf of the Virgo Collaboration.

TPPB19 A GUI Builder Environment Based on LabVIEW for the Virgo Project 202

  The Virgo project consists of a suspended Michelson Interferometer with two 3-km-long arms aiming to detect gravitational wave signals from cosmic sources. In order to support the ongoing Virgo commissioning activities and facilitate the transition to full operational mode, the need for new, quickly built, flexible, and graphically rich Graphical User Interfaces (GUI) arose. The challenge was to set up a GUI building environment able to deal with those requirements and to smoothly integrate it with the existing distributed control software framework. We have been able to fulfill these requirements by using LabVIEW and by enhancing its functionalities within three main components: a LabVIEW interface to the Virgo control framework, similarly to what has been done for other frameworks such as EPICS or Tango*, **; a common functions library; and a common building blocks. This GUI building environment required an initial effort of customization by establishing the right methodology and implementing the basic components, but has enabled the building of new GUIs with a high level of flexibility and maintainability.
