Visita de periodistas científicos al ESRF


Quince periodistas científicos podrán visitar del 21 al 23 de junio de 2009 la Instalación Europea de Radiación Sincrotrón (European Synchrotron Radiation Facility, ESRF). La fecha límite de inscripción es el 20 de mayo.

Esta es una gran oportunidad para conocer este instituto internacional financiado por 19 países, situado en Grenoble (Francia), que alberga la fuente de luz sincrotrón más potente de Europa y que recibe al año la visita de más de seis mil científicos que realizan ahí cerca de 900 experimentos.

Los gastos de viaje de esta visita para periodistas, que se desarrollará en inglés y español en la medida de lo posible, correrán por cuenta del ESRF.

Es imprescindible contactar con Montserrat Capellas Espuny, de la oficina de prensa del ESRF.

Visita de periodistas científicos al ESRF

Programa provisional

22 Y 23 JUNIO 2009
Arrival and check-in at the ESRF guesthouse.
Dinner in town


9am Welcome to the ESRF.
9.15-9.45 Introduction to the ESRF by Manuel Rodríguez Castellanos, head of the Industrial and Commercial Unit and head of the Director’s General office.
9.50 – 10.30 – Presentation of the ESRF Upgrade Programme by one of the directors of research.
10.30-11 – Coffee break
11- 11.45 – Presentation of Imaging at the ESRF by José Baruchel, head of the Imaging group. TO BE CONFIRMED
12-12.45 – Visit of the Experimental Hall.
13- 14.30 – Lunch with ESRF and ILL scientists
14.45 – 18.30 – Visit of the Institut Laue Langevin, the most intense neutron source in the world.
20.30 – Transfer to the restaurant for dinner
22.30 – Transfer back to hotel.


9- Meeting at the ESRF Central Building
9.15- 10.15 – Visit of BM16 and meeting with Trinitat Pradell, Universitat Politècnica de Catalunya.
Subject of research: Study of paintings in the XV century, between the end of the Gothic period and the beginning of the Renaissance.

The historical goal of this experiment is to obtain scientific proofs of the relationship between the different painters and schools during the transition from Gothic to Renaissance in the critical 15th AD century in Catalonia, finding out the influences and connections with other European regions. The study includes the investigation of a selection of master artworks belonging to the MNAC (Museu Nacional d’Art Nacional de Catalunya) by means of the analysis of pigments, binders, preparation layers and reaction/aging compounds. Goals: First, to establish a methodology including specific sample preparation and the selection of adequate chemical and structural analytical techniques with ten micron resolution for the full identification of submillimetric mixtures of compounds.  Secondly, to produce a database including all the information obtained from the pigments, reaction, alteration and aging compounds for use in future studies. The reproduction of the processes of synthesis following medieval treatises will be one of the keys of the study allowing a full and unambiguous characterization of the original materials. In order to study reaction (drying) and alteration and aging compounds, natural and artificial process will be induced to determine the physical and chemical mechanisms responsible.  

10.30- 11.15 – Visit of BM25

Subject of research: Photovoltaic cells, by José Carlos Conesa, Instituto de Catálisis, CSIC, presented by Germán Castro, scientist in charge of BM25
Scientists want to verify, using the X-rays at the ESRF, the chemical state and atomic environment of the transition metal (TM) in polycrystalline TM-substituted semiconductor sulphides of potential usefulness for building high efficiency photovoltaic cells. First experiment at the ESRF.

11.20 – 11.40 – Coffee break

11.40- 12.20 – Visit of a Macromolecular Crystallography beamline (ID23). Sean McSweeney, head of the Macromolecular crystallography group, will give an overview of the activity of the group, including industrial experiments, as well on the work on Deinoccocus radiodurans.

Deinoccocus radiodurans is a soil bacterium which has a tolerance for ionising radiation hundreds of times higher than most other organisms. Studying the genome of D. radiodurans has revealed several proteins which play a part in repairing the bacterium’s DNA after massive radiation damage. Work is currently underway at the ESRF to determine the structures, mode of operation, and partners for some of these proteins. The latest development in this work is documented in a Structure paper, which describes how one of the key actors in DNA damage repair UvrA sheds new light on the molecular mechanisms underlying the early steps of DNA repair.

12.30 – 13.45 – Lunch with ESRF scientists

14.00 – 15.20 – Visit of ID19
Subject of research: paleontological research at the ESRF.
Paleontologists from the University of Rennes (France) and the ESRF have found the presence of hundreds of animal inclusions in completely opaque amber from mid-Cretaceous sites of Charentes (France). The team used the X-rays of the ESRF to image two kilogrammes of the fossil tree resin with a technique that allows rapid survey of large amounts of opaque amber. At present this is the only way to discover inclusions in fully opaque amber. Having seen the amount of new species found, this spring the scientists have set up a database available to all the paleontology community with the 3D structures of the different animals and plants found.

Subject of research: Quantification of vessel trees from tumours down to the capillary level. Bert Müller, University of Basel.
Although there are treatments including surgery, chemical and radiation therapies are established, the aggressive proliferation of cancerous cells and the related blood vessel formation (angiogenesis) is still not well understood. This team from the University of Basel is trying to better track angiogenesis in order to develop more powerful strategies against cancer.

15.25 – 16.00 – Visit of ID22 and meeting with the scientist Gema Martínez-Criado. TO BE CONFIRMED
Subject of research: semiconductors and photovoltaics precipitators.
The photovoltaic industry has been growing at a steady annual rate of 25–30% over the past several years. This progress was driven chiefly by silicon-based solar cells, which now constitute nearly 90% of the global market. Although silicon is the second most abundant element in the crust of the Earth, it is typically found in an oxidized complex in nature. The refined and highly purified polysilicon feedstock used to fabricate commercial solar cells and integrated circuits is a much rarer commodity, with an annual production of approximately 30,000 tons. With continued growth in the photovoltaic industry, demand for silicon feedstock finally exceeded supply in 2004, provoking a drastic price increase for silicon feedstock and jeopardizing the continued growth of the photovoltaic industry. To eliminate dependence on high-quality silicon feedstock, the development of low-cost ‘solar-grade silicon’ has been proposed, which contains much higher concentrations of deleterious transition metal impurities. Martínez-Criado collaborates with a team from MIT, who is working in making cost-effective solar cells from low-cost, abundant, but impurity-rich feedstocks.

16.00 – Departure to Geneva airport for Barcelona flight (Easyjet, 18.40 – arrival  20.05)

16.00 – 18.30 – Time for interviews/ coffee break

18.30- Departure to Lyon airport for Madrid flight (Iberia, 20.40 – arrival 22.30)
