International Symposium on Utilization of Accelerators

São Paulo, Brazil
26 - 30 November 2001


[View the Provisional Programme, General Information and Hotel Reservation Form]


    Particle accelerators, originally developed for basic research in nuclear and particle physics, have matured into versatile tools for applications in other branches of science as well as in industry and medicine. The majority of accelerators are linear electron accelerators used by the industry for applications such as polymerization of plastics, waste and flue gas treatment, and sterilization of foodstuffs and medical devices. In addition they are in widespread use in hospitals for cancer treatment.

    In the electronics industry, ion accelerators are utilized for implanting atoms onto the surface of semiconductor materials. Ion implanters are also used for hardening surfaces of medical metal implants and bearings. In the medical field, small dedicated cyclotrons are producing isotopes for diagnostic as well as therapeutic use.

    Recently there has been increased interest in building dedicated proton accelerators of a few hundred MeV for treatment of deep lying tumors. Protons deposit most of their energy near the end of their path, minimizing the radiation dose to surface tissue and vital organs close to the target zone.

    Synchrotron radiation sources utilize electrons circulating for many hours in storage rings, interacting with specialized magnet systems and thereby emitting synchrotron radiation in the wavelength range from infrared radiation to Xrays. Synchrotron radiation is used increasingly in macromolecular crystallography to locate the position of atoms in large protein molecules, facilitating the understanding of the human genome and the design of new antiviral drugs. Synchrotron based x-ray fluorescence microprobe techniques explore the trace elemental composition of medical, environmental and historical samples. Synchrotron light will also support photolithographic techniques for manufacturing mechanical parts down to the size of hundredths of a millimeter ("nanotechnology").

    The programmes of the International Atomic Energy Agency in the Utilization of Accelerators are implemented through the Department of Nuclear Sciences and Applications and the Department of Technical Co-operation. The IAEA contributes to new developments, training, promotion and transfer of technology by organizing Consultants' meetings, Advisory Group Meetings and Co-ordinated Research Projects.

    The main objectives of Symposium are to bring together experts in the field to exchange information and review the status of current developments and applications, to discuss new trends and technologies, and to promote research collaboration between laboratories in IAEA Member States.


    The programme of the Symposium consists of invited lectures and contributed papers. Papers on the following topics will be considered for presentation at the Symposium.

    • Application of accelerators in industry
      • Treatment of foodstuffs and medicinal herbs
      • Sterilization of medical devices

      • Waste treatment

    • Application of synchrotron radiation sources
      • Science and materials technology
      • Polymers characterization
      • Molecular biology
      • Macromolecular crystallography

      • Ion sources
      • Vacuum systems
      • Magnet systems
      • Control systems
      • Dosimetric systems
      • New trends and developments


    All persons wishing to participate in the Symposium have to complete a Participation Form and send it to the competent official government authority (see Section 12) for subsequent transmission to the IAEA. A participant will be accepted only if the Participation Form is transmitted through the government of a Member State of the International Atomic Energy Agency or by an organization invited to participate. Participants whose designations have been received by the IAEA will receive further details about two months before the meeting.


    All papers - apart from invited review papers - must present original work; they should not have been published elsewhere.

    1. A camera-ready copy of an extended synopsis of 800 words (i.e. two A4 format pages of single spaced typing or equivalent, including any tables or diagrams and a few pertinent references) together with the completed Paper Submission Form and the Participation Form, must be sent to the competent official authority (see Section 12) for transmission to the IAEA to reach it before 29 June 2001.

      The synopsis has to give enough information on the contents of the proposed paper to enable the selection committee to evaluate it. Introductory and general matters should not be included. The synopsis - if accepted - will be reproduced in unedited form in the Book of Extended Synopses.

    2. If changes or corrections to an extended synopsis become necessary, a revised version may be sent to the IAEA before 15 October 2001 for inclusion in the Book of Extended Synopses.

      Authors are urged to strictly observe the above deadlines.

    Acceptance of a Paper/Poster

    To give sufficient time for discussion, the number of papers that can be accepted for oral presentation is limited. If the number of relevant and high quality papers submitted for selection exceeds the acceptable number, poster sessions may be arranged.

    Authors will be informed by the end of July 2001 whether their paper(s) have been accepted for oral presentation or as a poster on the basis of the extended synopsis. Authors of accepted papers/posters will receive at the same time the format specifications for the submission of the manuscript. It should be noted that the Agency reserves the right to refuse the presentation or publication of any paper that does not meet the expectations, on the basis of the information given in the extended synopsis.


    The proceedings of the Symposium will be published by the IAEA in unedited form in electronic format only (CD-ROM). All participants will receive a free copy of the proceedings.


    The costs for the organization of the conference 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 funds are available to support the attendance of selected specialists from developing Member States with low economic resources. Usually, only one travel grant may be awarded per country. To apply for a travel grant, please send a Grant Application Form that is typewritten or clearly printed through official government channels (see Section 12) to reach the Agency by 29 June 2001 together with Forms A and B. Incomplete or late applications cannot not be considered. The grants will be lump sums usually covering only part of the cost of attendance.


    The working language of the meeting will be English. All communications, synopses, abstracts and papers must therefore be sent to the IAEA in English.


    A preliminary programme of the Symposium will be sent to all participants before the meeting. The final programme and the book of extended synopses will be distributed upon registration.


    Detailed information on accommodation and other items will be sent to all designated participants about two months before the meeting.

  10. VISA

    Participants who require a visa to enter Brazil should submit the necessary application to the nearest diplomatic or consular representative of Brazil as soon as possible.
