WP12: TA6 – Trans-national Access to ELETTRA
Provision of access to the following infrastructure(s): ELETTRA
Description of the infrastructure
The Elettra storage ring is operated in top-up mode at 2.0 and 2.4 GeV for >5,000 hours/year of user operation. Users have access to 26 beamlines, of which 18 can work in parallel; during the project, two more beamlines will become operational. A wide variety of experimental techniques are available, including photoemission and spectromicroscopy, crystallography, low-angle scattering, dichroic absorption spectroscopy, X-ray imaging, powder diffraction etc. They are complemented by 13 laboratories for sample preparation and characterisation but also including scientific computing. Elettra serves the communities of material science, solid-state chemistry, atomic and molecular physics as well as biology, medicine and cultural heritage.
The FERMI free electron laser is a state of the art seeded free electron laser based on high gain harmonic generation. Two FEL undulator lines are optimized to generate radiation in the ranges 100-20 nm (FEL-1) and 20-4 nm (FEL-2). The seeded scheme allows complete control and reproducibility of the photon beam characteristics such as wavelength and intensity; FERMI also offers beam polarisation control. Three beamlines are available for user-assisted commissioning: Diffraction and Projection Imaging (DiProI), Low Density Matter (LDM) and Elastic Scattering from Matter under Extreme Conditions (EIS-TIMEX). During the project, three additional ones will become available, dealing with time-resolved spectroscopy, magnetodynamical studies and TeraHertz pulses experiments.
ELETTRA is the Italian representing entity within the Central European Research Infrastructures Consortium (CERIC-ERIC) and presently hosts its statutory seat in Trieste. 14 Elettra beamlines devote 10% of their access time to users coming in through CERIC-ERIC, which allocates multi-technique experiments following international peer-review. Elettra is part of the AREA Science Park and perfectly integrated in a vital scientific environment including the International Centre for Theoretical Physics and the International Centre for Genetic Engineering and Biotechnologies, both of which are under the aegis of the United Nations. Elettra is an associate of the IAEA (International Atomic Energy Agency) and member of the Central European Initiative network (CEI).
|Name of the infrastructure (and
its installations, if applicable)
The infrastructure is composed of two photon sources: the ELETTRA storage ring and the FERMI free electron laser.
|Location of the infrastructure||Trieste, ITALY|
Modality of access & application procedure
|Modality of access||Since 2014 users can use the Standardized Proposal Format (SPF) available at the portal wayforlight.eu, as the European lightsources single entry point, for proposal submission to ELETTRA: users can fill the SPF on wayforlight.eu and be automatically redirected to the Virtual Unified Office for proposal finalization. In CALIPSOplus, also FERMI users will exploit the SPF XML route for proposal generation.
Calls for proposal:
Elettra advertises its calls for proposals on its website and on the wayforlight.eu portal as the European lightsources single entry point.
Users normally arrive to the facility one day before the measurement run and leave one day after. For specific experimental setups, remote access is also possible. Experiments last five-seven days at Elettra and up to 10 days at FERMI. The collected data are made available to the users in digital form, and managed according to the ELETTRA scientific data policy. After the experiment, users are requested to fill an online questionnaire, used by ELETTRA to improve its services and by the Proposal Review Panel to complement the evaluation of future proposals.
|Offered support||Users coming to the infrastructure are assisted by a group of trained scientists at each beamline, typically a senior scientist, a junior scientist and a post-doc. The scientists are available on site or on call to solve experimental problems.The users operate in a multi-disciplinary environment that stimulates cooperation and cross-fertilisation, also thanks to the top-level scientific centres in the facility’s neighbourhood.
More information about Trans-national Access funding by ELETTRA and FERMI you will find here.
|Outreach to new users||Beamline data sheets are also available on wayforlight.eu. Find more information on the infrastructure here: ELETTRA@wayforlight.eu, FERMI@wayforlight.eu as well as on the available beamlines here: ELETTRA and FERMI BEamlines@wayforlight.eu, respectively.
Elettra will actively participate in WP2-NA1 „User tools for access and data management“ and WP4-NA3 „European Light Sources for Industrial Innovation plus (ELSIIplus), which include specific outreach activities for new users.
In particular, Elettra will favour participation of users from new EU Member States (EU-13) thanks to its role in the CERIC-ERIC distributed Research Infrastructure. Elettra will also welcome SMEs users as selected within WP22-TA17 „Tailor-made for SMEs Trans-national Access (TamaTA)“.
|Review procedure||The selection of users for the public beamtime is operated on the basis of scientific merit by two Proposal Review Panels of international independent experts, one for the Elettra storage ring and one for the FERMI FEL, organized into several thematic sub-panels. The composition of the panels changes with time due to the reviewers’ availability and the growth of new scientific areas.
The evaluation steps are:
The panel rates each proposal using a number code (one to five with 1 as top level), accompanied by specific comments. Following scientific merit, Elettra applies additional criteria for granting users support. In particular, users are requested to self-declare if travel support is “crucial” for their research, i.e. if they would not be able to come to Elettra unless monetary support is provided. This criterion has proven to be extremely effective to select, among excellent users, those who really deserved financial support in the past ten years. Additional criteria consider new users and users from countries with no national light source.
