The CNR - Evaluation Panel (commissione.gilda AT cnr.it) invites the Italian Users to submit a letter of intents for Long Term Projects with deadline Apr. 3rd 2016 (see text, in italian, here). The next deadline for conventional Rolling Access Projects on the italian quota is on May 8th 2016.
Feb 18th 2016
- The italian commission has finally completed the selection of the proposals and the results are resumed in the document LISA-CNR Review Panel Results I_2016. Following this decision, the schedules for Run2-16 and run 3-16 have been defined and can be found in the LISA Schedules page.
- Next March 1st 2016 is the deadline for the submission of proposals in the ESRF beamtime quota. Proposals by national and international users can be submitted at the ESRF user portal (https://wwws.esrf.fr/misapps/SMISWebClient/protected/welcome.do)
- The 2015 annual report of LISA has been published. You can find it with the latest news and scientific highlights of the beamline in the followin g document: LISA_report_2015
- There is the opportunity for a PhD thesis at the Ecole Doctorale de Physique of the Université Joseph Fourier (Grenoble) under the supervision of F. d'Acapito and in collaboration with CEA-LETI and Liège University. The title is "Impact of nanometric confinement of chalcogenide materials on their structure and phase change properties" ; more details at https://www.adum.fr/as/ed/proposition.pl?site=phys or https://www.adum.fr/as/ed/voirproposition.pl?langue=fr&site=phys&matricule_prop=10764 The thesis can be supported by the UJF; please find all the details for the applications at the address: https://www.adum.fr/as/ed/page.pl?site=phys&page=candidature.

Deadline for proposal submission on the italian beamtime quota: next Nov. 8th 2015.
The submission of proposals for beamtime within the Italian quota for the first Semester 2016 is now open with deadline on Nov. 8th 2015. Only standard “rolling access” (RA) proposals will be evaluated for the present Call (Beamtime from March 2016). The CNR panel is currently evaluating the possibility of a new Call of Block Allocation Group (BAG) for the Italian beamtime on LISA, that will be launched later. Proposals can be submitted at the ESRF user portal . Detailed instructions can be found here.
LISA beam time allocation panel
The CNR panel, renewed on May 2015, intends to evaluate the RA Proposals according to the following priority criteria:
Main criteria (individually evaluated)
- Scientific Interest and originality/novelty
- Clear description of the objectives of the Proposal
- Evaluation of: detailed expected results, feasibility, previous experience and reports.
The final selection, in case of a tie, will take into account the previous history of the Proposal and will favor those proposals that include Ph.D. students among the proponents. This should be declared in the proposal.
LISA is at present fully in operation and the schedules for the present and forthcoming runs are available at the following page.

Jun. 25th 2015
The procedure for the procurement of the new monochromator has started. The device is foreseen to be operational by the end of year 2016.
Jan 8th 2015
The new contract between CNR and ESRF for the 5 year operation of the italian CRG beamline at the port BM08 of ESRF has come into force on Jan 1st 2015. A deep refurbishment plan for the instrumentation is foreseen to be realized in the forthcoming months that will provide to the users a completely new instrument. For this reason, the project name will be changed in LISA; a description of the new project can be find in the LISA presentation document.
The (old) GILDA Beamline
The Italian Collaborating Research Group GILDA at ESRF is a general purpose beamline using a bending magnet source. It is financed by three major italian public research Institutes (Consiglio Nazionale delle Ricerche CNR , and Istituto Nazionale di Fisica Nucleare INFN) and is the result of a collaboration a number of Italian Universities namely Cagliari, Camerino, Roma "Tor Vergata", "Roma Tre", Parma, Trento.
It is operational since Sept 1994, and is mainly dedicated to the investigation of local structures. To this purpose, X-ray Absorption Spectroscopy as well as X-ray Diffraction are used on the beamline in the energy range 5-80 keV. A high energy resolution is ensured by using Si(311) and Si (511) monochromating crystals. The GILDA beamline consists in four experimental hutches: the first contains the optical elements and the others the experimental apparata.
The first experimental hutch, in the 1:3 focal configuration which ensures the maximum flux, is dedicated to X-ray Absorption Spectroscopy (XAS). The wide energy range of the beamline makes GILDA well-suited for XAS investigations on heavy elements with the possibility to access the K absorption edges from Ti to Au. Experiments are carried out in transmission, fluorescence and total electron yield modes. For the study of highly diluted samples a 13-elements high purity Ge detector is currently used (current limit sensitivity: 10 14 at/cm 2). Surface experiments in total reflection mode (ReflEXAFS) are performed in a dedicated experimental chamber.
The second hutch, in 1:1 focal geometry, is dedicated to X-ray scattering and diffraction. It is equipped with a two circle diffractometer with an angular step of 0.28 arcsec and a reproducibility of 2 arcsec. Crystal analyzers, solid-state detectors and scintillators are used to perform anomalous scattering on amorphous materials, and powder diffraction with an instrumental angular resolution lower than 0.01 degree. The recent installation of an Image Plate detector has permitted the development of an apparatus for time-resolved powder diffraction.
A third experimental hutch at the end of the beamline is available for users who wish install their own apparatus. An ultra high vacuum chamber fully equipped for surface preparation and characterization is available for EXAFS investigations in total and partial electron yield mode.
