IAEA Technical Meeting on
Use of Neutron Beams for High Precision Nuclear Data Measurements


10 - 14 December 2012

Budapest, Hungary



The maintenance of existing and development of new nuclear technologies rely on the availability of atomic, molecular and nuclear data to provide accurate numerical representations of the underlying physical processes. Essential data include energy-dependent cross sections, the energy and angular distributions of reaction products for many combinations of target and projectile, and the atomic and nuclear properties of excited states, and their radioactive decay data.
Nowadays modern nuclear facilities and applications have reached a high degree of sophistication, where the safe and economical operations of these complex technologies require detailed and reliable design calculations. While simulation calculations are becoming more and more economical with the rapid advances in computer technology and increased predictive power of physical models, the confidence of these calculations is still largely determined by the accuracy of the atomic and nuclear input data. In addition to the field of fission reactor technology, there are also many other nuclear applications that are of growing economic significance and require substantial data input regarding neutron induced reactions like nuclear fusion, production of radioisotopes, neutron therapy, spallation neutron sources, non-destructive testing, multi-elemental analysis, etc. In this context, use of neutron beams is the most frequently employed technique to provide high quality experimental data for neutron induced reactions in the broad neutron energy range.  All these measurements can be grouped into two main categories:

All these facilities have their specific characteristics in terms of neutron beam intensities and energy resolutions, associated instrumentation and data acquisition systems, developed dedicated experimental programmes. A number of new powerful neutron sources/facilities have recently become operational (e.g. J-PARC in Japan, SNS in USA) or are in the licensing/planning stage (e.g. CARR and CSNS in China, PIK in Russia, NFS in France, new EAR2 beam line at CERN, ESS in Sweden,…). Most of them propose very ambitious nuclear data measurement projects either exclusively or as part of their broader utilization programmes and strategies.

The technical meeting will provide a forum to exchange of good practices, lessons learned and practical experiences in use of neutron beam facilities and associated instrumentation, both accelerator and research reactor based, in provision of high precision nuclear data. Present status and future developments of neutron beam facilities world-wide, both accelerator and research reactor based, will be addressed. The meeting will concentrate on the following major topics:

The principal output of the meeting will be a meeting report summarizing present status and future development of neutron beam facilities and associated instrumentation, both accelerator and research reactor based, in provision of high precision nuclear data for nuclear research and various applications. This document will also include good practices and lessons learned from international cooperation and multi-user facilities in this particular area. The meeting report, including individual participant contributed papers, will serve as an initial working material for the future publication “Compendium of Neutron Beam Facilities for Nuclear Data Measurements”.  This document will be reviewed, finalised and published by the IAEA.

The format of the meeting will be invited and contributed oral presentations presented in sessions devoted to special topics, with subsequent discussions and breakout sessions. An electronic projector with a computer capable of reading CDs and memory sticks will be available (Power Point or Acrobat recommended). The official language of the meeting is English. No interpretation will be provided. The meeting will start at 09:30 on 10 December 2012, and will be concluded by 17:00 on 14 December 2012.

In order to participate in the meeting, the following two steps must be completed:
1) Abstract Submission
Persons wishing to make a presentation must submit an abstract of maximum one page in total length, in electronic format directly to the Scientific Secretary ( The abstract must be text only and must contain the author’s name, affiliation and e-mail address. Acceptable file format is Microsoft Word. The authors should make sure that the files do not include copyrighted fonts or other impediments for reproduction.The abstract template can be downloaded fromTemplate_Abstract.doc or requested from the Scientific Secretary.
The one page abstract must be received by 10 October 2012 at the latest. The abstracts will be evaluated by the Scientific Committee, and authors informed of the acceptance of their contributions by e-mail, by 20 October 2012. The programme agenda and a book of abstracts will be prepared and e-mailed to all accepted participants as PDF file attachment before the meeting.
Important: Contributors of material to be included in the IAEA’s proceedings are required to assign all copyrights or rights to publish to the IAEA (form B).

2) IAEA participation
A request for participation will only be accepted if the Participation Form (form A) is transmitted through the appropriate Governmental representative authority (i.e. Ministry of Foreign Affairs, National Atomic Energy Authority) requesting nomination and, if the IAEA receives the nomination by 10 October 2012. Persons from the IAEA Member States or invited international organizations are eligible to attend. Participants should be actively involved in the subject matter of the meeting. All persons wishing to participate in the work of this meeting are requested to complete a Participation Form (form A) and send it as soon as possible to the IAEA. Participants whose designations have been received by the IAEA will receive further details approximately 6 weeks before the meeting.

The presentations should be prepared either as a Power Point file or Adobe PDF format file, complete with all text, figures and tables. All presentations will be converted as received, to an Adobe PDF file and placed on memory sticks for distribution to all participants at the end of the meeting.

The manuscripts will be prepared to be included in the meeting proceedings compiled by the Agency. Authors must submit a signed Paper Submission Form (form B) to the IAEA for copyright purposes. Electronic version of papers will be collected during the meeting. For detailed instructions regarding how to prepare the manuscript please follow the format of available template. The paper template can be reloaded from: Template_Paper.doc or requested from the Scientific Secretary.

The costs for the organization of the meeting are borne by the IAEA and the Host Government. No registration fee is charged to participants. As a general rule, the IAEA does not pay for participants’ travel and living expenses. However, limited financial support is available to assist the attendance of selected experts who will make a presentation, principally those from developing Member States. Usually only one grant for financial support is awarded per Member State. If participants or governments wish to apply for a grant on behalf of one of their experts, they should ensure that applications for grants are:

Applications that do not comply with these requirements will not be considered. The grants awarded will be in the form of lump sums and will be paid prior to the meeting. Grants for financial support will be announced around 20 October 2012.

The IAEA will send official invitation letters to designated participants which are intended to assist with visa arrangements if needed approximately 6 weeks before the meeting. Participants requiring a visa to enter Hungary should submit the necessary application to the nearest diplomatic or consular representative of Hungary in their country as soon as they receive the official invitation letter.

It is the responsibility of the participants to arrange their accommodation. A list of hotel for reference and detailed information on transport arrangements to/from Budapest and other organizational items will be sent to all designated participants approximately 6 weeks before the meeting.
