The third version of the AMBER data reduction software
We present the third release of the AMBER data reduction software by the
JMMC. This software is based on core algorithms optimized after several years
of operation. An optional graphic interface in a high level language allows the
user to control the process step by step or in a completely automatic manner.
Ongoing improvement is the implementation of a robust calibration scheme,
making use of the full calibration sets available during the night. The output
products are standard OI-FITS files, which can be used directly in high level
software like model fitting or image reconstruction tools. The software
performances are illustrated on a full data set of calibrators observed with
AMBER during 5 years taken in various instrumental setup.Comment: To be published in the proceedings of the SPIE'2010 conference on

ETD@ANRT
International audienceThe poster presents the main activities and new projects of the French National Reproduction Centre for PhD dissertations (ANRT) at Lille, especially in the field of electronic theses and dissertations.Research method/procedureThe poster contains figures, statistics, technical and IT ressources and project descriptions, together with screenshots, based on annual activity statistics, inventories, reports, communications, agreements etc.Anticipated resultsSince 45 years, ANRT[1] is a central part of the French national infrastructure for the dissemination and preservation of PhD dissertations. First as a printing office, than as a microfiche and a print-on-demand service, ANRT has become over the years a major public digitization centre for theses, dissertation and other scientific heritage material (books, journals, manuscripts, photos...).The ANRT collections contain 220,000 PhD dissertation in all scientific domains, all of them on microfiche, 80,000 also on digital support (image and text files). The ETD related activities and projects are: Digitization of new PhD dissertations not yet submitted in digital format. Retrodigitization of dissertations on microfiches and in print format, for preservation on local university servers and/or dissemination via institutional repositories and digital libraries. Deposit of Lille PhD dissertations in social sciences and humanities in the national ETD infrastructure (STAR). Retrodigitization of Lille Master theses for local preservation and dissemination in the academic intranet and/or open access. Research projects in the field of open access to ETDs, text and data mining, linked data and the processing of research data produced by PhD students. Education of LIS BA and Master students in digitization techniques and equipment.ANRT is member of the ETD2016 organizing committee. The poster will document its rapid transition from the bygone print world to the digital age of ETD and open science and its potential use of new ICT tools.Practical implications/originalityThe poster will present the resources, capacities, activities and projects ANRT to an international audience, in order to extend its professional network and foster international partnerships in the field of ETD processing and research.ReferencesPaillassard, P., Schöpfel, J., Stock, C., 2007.

a research support librarian
International audienceThe poster shows the different activities of a research support librarian, a new profile at the academic library of the University Lille social sciences and humanities campus (formerly Lille 3).Since 2012, the university library in Lille 3 tries to lead a research support policy. It is not only to develop information resources in connection with the areas of research, but also to respond to changing needs and practices of researchers.This poster aims to present the diversity of services (open archive, workplaces dedicated, digital library, customized workshops) and rich collections (archives, press, literature). Recovery and the increased visibility of the scientific production of researchers are at the heart of these support services to research that develop in academic libraries
Neutrons, nuclear energy and the role of level densities and strength functions: May LICORNE be of any help?

Development of a kinematically focused neutron source with the p(7Li,n)7Be inverse reaction
Directional beams of neutrons can be produced, if a nuclear reaction, which emits neutrons, is initiated in inverse kinematics with a heavy ion projectile bombarding a light target. In this paper we investigate the use of the p(7Li,n)7Be inverse reaction to produce kinematically focused, quasi-mono-energetic neutron beams with a view to develop such an unusual neutron source for fundamental and applied nuclear physics studies. An experiment was carried out to validate the concept and to test the viability of two types of hydrogen-rich solid targets: polypropylene and TiH2. Neutron time-of-flight/energy spectra at 3 m distance from the source have been measured at 7Li bombarding energies of 13.5, 15, 15.5, 16, and 17 MeV, and neutron backgrounds from parasitic reactions have been characterized. The neutron angular distribution in the laboratory has been measured at 15 MeV. A Monte-Carlo code based on two-body relativistic kinematics has been developed and validated by comparison with the experimental data. Code-based extrapolations have then been used to deduce neutron energy spectra and maximum neutron fluxes available for future irradiation of samples placed in the neutron beam at small distances. For neutrons produced with thin View the MathML source and thick View the MathML source polypropylene targets the maximum available fluxes are calculated to be 107n/s/sr and 7×107 n/s/sr respectively. The development of a dedicated facility to produce kinematically focused neutrons is discussed
Prompt γ-rays from the Fast Neutron Induced Fission on 235,238U and 232Th
International audiencePreliminary results from the first experiment using the LICORNE neutron source at the IPN Orsay are presented. Prompt fission gamma rays from fast-neutron induced fission of 238U, 232Th and 235U were detected. Thick samples of around 50 g of 238U and 232Th are used for the first part of the experiment. An ionisation chamber containing ∼ 10 mg samples of 238U and 235U to provide a fission trigger is used for the second part of the experiment. Gamma rays have been detected using 17 high efficiency BaF2 detectors and 6 LaBr3 scintillator detectors
