WP15: TA10 – Trans-national Access to DAFNE-SPARC
Provision of access to the following infrastructure(s): Laboratori Nazionali di Frascati (LNF) dell’INFN – DAFNE and SPARC
Description of the infrastructure
The Frascati National Laboratories (LNF) are the oldest and biggest laboratory of INFN (Istituto Nazionale di Fisica Nucleare). The first Italian synchrotron radiation facility was built at the LNF and the experience in synchrotron radiation activities was developed using for many years, the electron storage ring, ADONE. Nowadays DAΦNE, a high luminosity collider (0.51 GeV), designed for a broad program in high-energy physics, is being used and with its characteristics it is also providing intense synchrotron radiation beams.
DAΦNE-Light is the INFN-LNF Synchrotron Radiation Facility. Of its five beamlines, two are wiggler beamlines, the soft X-ray and the UV one, while the other three beam-lines, SINBAD-IR, HEB (60-1000 eV) and LEB (35-200 eV), collect the radiation from bending magnets. The Synchrotron Infrared beam-line, SINBAD-IR, covers the whole infrared domain from 10 to 10,000 cm-1 and has two end stations. It is equipped with an IR microscope, a Focal Plane Array detector for the IR imaging, a liquid He cryostat to perform low-temperature experiments, and a diamond anvil cell for high-pressure experiments. One of the two branches of the IR beam-line has been recently dedicated to micro-spectroscopy and FT-IR imaging on biological tissues and cells at micrometric spatial resolution. The soft X-ray beam-line delivers light in the energy range 900 eV – 3100 eV. The main research activity here is focused on X-ray Absorption Spectroscopy. Experiments are performed at the K edges of light elements starting from Na and at the L and M edges of elements with higher Z values. Part of the wiggler emission is also deflected to go in the UV beam-line that is able to deliver light in the range (200÷600) nm within a (0.1÷0.3) % spectral band. The XUV beam lines were designed and built to perform various spectroscopies like photoemission, core absorption and emission and are equipped with end stations with low-temperature angle resolved photo-emission setup, LEED, mass spectrometer and sample preparation systems that are in use.
Concerning novel radiation sources and advanced accelerators concepts, the LNF laboratory has developed the SPARC_LAB (Sorgente Pulsata Auto-amplificata di Radiazione Coerente) test facility. This facility is based on the combination of high brightness electron beams, from the SPARC photo-injector, with high intensity ultra-short laser pulses from “FLAME”. Their joint presence allowed the investigation of advanced radiation sources, e.g., coherent monochromatic X-ray and high peak power THz radiation. These features, and in particular an energy per pulse up to 40 μJ and a pulse duration shorter than 100 fs rms, make the SPARC_LAB THz source an appealing source for nonlinear THz spectroscopy.
|Name of the infrastructure (and
its installations, if applicable)
|Laboratori Nazionali di Frascati (LNF) – DAFNE and SPARC|
|Location of the infrastructure||Frascati (RM), ITALY|
|Services currently offered by the infrastructure||In the last years, research activity at LNF attracted a sizeable amount of external users, with a relevant number of foreign scientists. Concerning the DAΦNE-Light Laboratory, an average of about 30 experiments per year have been performed by Italian and EU users in the framework of the INFN experiments, a collaboration with Italian Universities and TARI (Transnational Access to Research Infrastructures).|
Modality of access & application procedure
|Modality of access||All users willing to have beamtime at the LNF facilities will submit their requests using the DaΦne-Light portal.
Calls for proposal:
From DAΦNE-Light portal portal the filled in templates with their data and the safety information on their samples, will be linked to the wayforlight.eu portal to use the standardized proposal. Users will be notified of the scheduling of their experimental run.
|Offered support||Dedicated persons act as interface between the users and the beamlines, researchers and technicians follow the users of LNF facilities. The LNF laboratory is located about 20 km from the center of Rome and easily reached by car, plane, bus or train. The LNF laboratory area hosts a travel office, a restaurant, different cafeterias and a bank. A guesthouse is also available on site.
More information about the Trans-national Access funding by DAΦNE-SPARC you will find here.
|Outreach to new users||Beamline data sheets are also available on wayforlight.eu (Find more information here: infrastructure DAΦNE@wayforlight.eu and DAΦNE-Light email@example.com)|
|Review procedure||A User Selection Panel (USP) evaluates the proposals. The USP bases the evaluation with respect to the principle of scientific merit and transparency criteria.
The proposals are distributed to the USP members well in advance before the meeting. A feedback with the users after the USP decisions is represented by writing to all applicants, approved and rejected, with detailed motivations of the decision. Five members form the USP, chosen based on their internationally recognised experience.
