The evolution of the hardware platforms, the modernization of the software tools, the access to the codes by a large number of young people and the popularization of the open source software for scientific applications drove Dr. Luca Rebuffi (ANL) and Dr. Manuel Sanchez Del Rio (ESRF) to design OASYS (ORange SYnchrotron Suite), a completely new graphical environment for modeling beamlines and X-ray experiments. The implemented software architecture allows to obtain not only an intuitive and very-easy-to-use graphical interface, but also provides high flexibility and rapidity for interactive simulations, allowing to make quick configuration changes to compare multiple beamline configurations. Its purpose is to integrate in a synergetic way the most powerful calculation engines available. OASYS integrates different simulation strategies via the implementation of adequate simulation tools for X-ray Optics (e.g. ray tracing and wave optics packages). It provides to several tools a language let communicate by sending and receiving encapsulated data. Python has been chosen as the main programming language, because of its universality and popularity in scientific computing. The software Orange, developed at the University of Ljubljana (SLO), is the high level workflow engine that provides the interaction with the user and communication mechanisms. OASYS itself looks like an empty container. APIs are released as distinct groups of widgets called Add-Ons, and the can be installed, uninstalled or upgraded by a using a specific form (Add-On manager): the list of available APIs is shown and the user can customize its OASYS appearance. Add-Ons are python packages that follow the Python Package Index (Pypi) specifications, and they are all uploaded in the Pypi database. OASYS automatically detect when one or more Add-Ons have a newer version in the Pypi database, and propose to the user the upgrade them, in order to keep the installed APIs always at their last release. The available APIs are: Shadow4, SRW, XOPPY (XOP in PYthon), XRayServer, DABAM. A video introduction to OASYS can be found here |
