The XRAY Virtual Organization

The users of a Grid infrastructure are divided into Virtual Organisations (VOs), abstract entities grouping users, institutions and resources in the same administrative domain.

The WLCG/EGEE VOs correspond to real organisations or projects, such as photons light sources experiments community at synchrotrons. An updated list of all the EGEE VOs can be found at the CIC portal.

Before WLCG/EGEE resources can be used, a user must read and agree to the WLCG/EGEE usage rules and any further rules for the VO he wishes to join, and register some personal data with a Registration Service. Once the user registration is complete, he can access WLCG/EGEE.

XRAY VO was created with the aim of study the feasibility of using GRID facilities at synchrotrons experiments, and includes the collaboration between the ESRF and other 3 synchrotron partners in Europe. Further information of this VO can be found at the Operational Portal and the resources available at XRAY VO can be consulted at the GOC DB center.
