ORGANISATION FOR ECONOMIC CO-OPERATION AND DEVELOPMENT ORGANISATION DE COOPERATION ET DEVELOPPEMENT ECONOMIQUES Nuclear Energy Agency Agence pour l'Energie Nucleaire 12, Boulevard des Iles F-92130 Issy-les-Moulineaux FRANCE From: Dr. Pedro VAZ Telephone: +33 (1) 45 24 10 74 Telefax: +33 (1) 45 24 11 10 E-mail: vaz@nea.fr To: Participants in SATIF-4 and SARE-4 Subject: Official Announcement and Call for Papers - SATIF-4 Meeting Date: 8th April 1998 Particle accelerators have evolved over the last decades from simple devices to powerful machines and are having an increasingly important impact on research, technology and lifestyle. Today, they cover a wide range of applications. It has become common practice to use them also for Material Science and medical applications. In recent years, requirements from new technological and research applications have emerged and the number of accelerator facilities in operation, being commissioned, designed or planned has significantly increased. Their parameters (such as the beam energy, beam currents and intensities, targets composition, etc.) vary widely giving rise to new Radiation Shielding aspects and problems. The activities of the Task Force on Shielding Aspects of Accelerators, Targets and Irradiation Facilities (SATIF) are sponsored by the OECD Nuclear Energy Agency (NEA) and its Nuclear Science Committee (NSC). The main objectives of the SATIF Meetings are: * to promote the exchange of information among experts in the field of accelerator shielding and related topics, * to identify areas where international co-operation can be fruitful and * to carry on a program of work in order to achieve progress in specific priority areas In this context, and on behalf of its Technical and Organizing Committee, we announce that the fourth Specialists Meeting on Shielding Aspects of Accelerators, Targets and Irradiation Facilities (SATIF-4) will take place in Knoxville, Tennessee, U.S.A., from 17-18 September 1998, jointly organized by * the OECD Nuclear Energy Agency * the Oak Ridge National Laboratory (ORNL) * the Radiation Safety Information Computational Center (RSICC) and * the Shielding Working Group of the Reactor Physics Committee of Japan, following the fourth Meeting on "Simulating Accelerator Radiation Environment" (SARE-4). The Chairperson of the SATIF-4 Meeting will be Dr. Robert Roussin from ORNL. ************************** Similarly to the preceding SATIF Specialists Meetings, e.g. SATIF-1 in 1994 at Arlington, Texas (U.S.A.), SATIF-2 in 1995 at CERN, Geneva (Switzerland) and SATIF-3 in 1997 at the University of Tohoku, Sendai (Japan), special emphasis will be devoted during the SATIF-4 Meeting to monitor the progress achieved in agreed projects, to identify and initiate new co-operative actions and to improve common understanding of problems that have technical and safety significance in the following areas: * Basic data (new measurements, compilation of existing neutron, proton, light ion and pion cross-section data in the intermediate energy range above a few dozens of MeV, forward bremsstrahlung yields from thick targets at energies above 100 MeV, photoproduction data namely photonuclear cross-sections and photonuclear yields and angular distributions for all common elements at all energies, photopion yields and angular distributions at energies above 200 MeV, isotope production data, etc.) * Nuclear Models and Computer Codes in the Intermediate Energy Range (code validation, intercomparison of codes, comparison between experimental data and predictions from existing computer codes implementing nuclear models) * Shielding Experiments (measurements of forward and lateral attenuation of iron and concrete for proton and ion accelerators up to a few tens of GeV and as deep as possible, measurement of forward and lateral attenuation at electron accelerators) * Benchmark data (development of new benchmark exercises, further compilation of existing benchmark data sets, etc.) * New or better measurements of many activation detector excitation functions (in particular C-11 production by neutrons and pions in the energy range above 100 MeV and Bi production) * Anthropomorphic computational models (compilation of existing models, phantom geometries and material compositions, etc.) * Conversion coefficients (calculation methods and results for high-energy radiation) In order to establish the approximate number of participants and presentations made we would appreciate if you could fill in the enclosed preliminary participation form and return it to us by the end of April. Commitment to participation is not requested at this stage, the information is needed only by the local organizers and for planning purposes. For information concerning the local organization, please refer to: http://www-rsicc.ornl.gov/sare/sare.html We look forward to a successful SATIF-4 Meeting.
