EUCALL focuses on the overlap between accelerator-based and laser-based light sources. It established a sustained collaboration with the aim of harmonizing and optimizing the landscape of advanced light sources. The development of such connections will benefit the scientific users of these facilities through better and more efficient services.

Building on input from users, EUCALL advised how advanced light sources could better suit the needs of the user community at large. EUCALL analyzed the suite of instrumentation at the European advanced light source facilities and provides recommendations for their individual and joint development.

Analyzing the advanced light source landscape

EUCALL compiled detailed information about 22 characteristics at 121 different experiment setups at 17 advanced light sources across Europe. This data collection includes information regarding the properties of the light generated, the types of experimental techniques employed, and the properties of associated technical infrastructure such as optical lasers and sample delivery systems. The advanced light source experts involved in EUCALL performed a comprehensive analysis of these data and developed recommendations for optimal use of these facilities, with regard to scientific and user needs. These recommendations include maintaining a varied range of instruments in order to support a broad scope of scientific applications, even providing a certain level of overlapping technologies at the various advanced light sources to increase their availability; encouraging experimental campaigns that make use of complementary measurements at neighbouring advanced light source facilities; or developing FEL and optical laser instrumentation such as to reach the stability, operational performance, and versatility of synchrotron instruments. Additionally, it is recommended that, as technologies for miniaturizing advanced light sources develop, table-top or local laboratory X-ray setups be built and used for preparatory investigations, thereby better preparing experiments at large-scale advanced light sources and more efficiently using these light sources.

Enhanced availability of information via Wayforlight

The collected landscape data were considered to be very useful for users. EUCALL therefore investigated ways to make this catalogue of properties publicly available in such a way that it could be accessible beyond the project’s timespan. The information was incorporated into the Wayforlight portal (www.wayforlight.eu), a platform for
European accelerator-based light sources. Wayforlight was created under the EU project CALIPSO, and it is further developed under the Horizon 2020 project CALIPSOplus. The portal maintains a searchable public database of instrumentation at synchrotron and FEL facilities. Using Wayforlight, scientists can find out which facilities might be most suitable for their measurements by comparing the instrumentation available at each. The EUCALL landscape dataset integrated the laserdriven advanced light sources into Wayforlight for the first time. The newly augmented Wayforlight database becomes publicly available in September 2018. Users will now be able to explore the database and directly compare instrumentation at a much larger number of facilities at a greater depth, allowing them to develop more elaborate comparative and repeat experiments at various facilities.
