Starting in 2008, the European Theoretical Spectroscopy Facility (ETSF) has been providing services, ranging from performing on-demand simulations to developing and enhancing theories and software, as well as training users and developers. The ETSF involves close collaborations between several groups of theorists and a broad community of experimental and industrial researchers who wish to address spectroscopy issues using modern first-principles approaches.

Theoretical spectroscopy reveals the mechanisms of electronic excitations, lets us explore the interaction between light and matter at the quantum level, and can predict new properties of materials. This combination of quantum mechanics theory and numerical simulations is a complementary approach to experiments, and has now become essential in the fields of biology and nanotechnology.

The ETSF is a professionally-managed knowledge centre in which the expertise, the theory and the software can benefit to the users in many different ways. It is organized as a "virtual synchrotron", with beamlines corresponding to different kinds of spectroscopy. Twice a year, the users can apply to get theoretical support for their projects. The latter are evaluated by a panel external to the ETSF and directed to the appropriate beamline(s) when accepted.

One of the most important components of ETSF is the integration of software developments, since all its research groups have complementary theoretical capabilities and software tools. Steps have been taken to standardize the exchange of data and the programming practice, relying on the Free Software philosophy. They have resulted in a file format and a library for platform-independent data-exchange, codename ETSF I/O. Other ongoing efforts include the development of GUIs, various tools, a live-CD, the tuning of the codes for massively-parallel high-performance computing environments, and the creation of a "ETSF Users Community". Our software is distributed under the GNU GPL or LGPL licenses, depending on its nature.

Multi-field engineer and PhD in physics, Yann Pouillon is carrying out research in quantum physics, mainly on nanostructures and biological molecules, at the University of the Basque Country, in Donostia-San Sebastián, Spain. He is very actively involved in the software aspects of the management of the European Theoretical Spectroscopy Facility (ETSF).
