The Abdus Salam International Centre for Theoretical Physics (ICTP) and the Instituto Nazionale per la Fisica della Materia (INFM) will jointly organise the School & Workshop on "Spectroscopic Investigation of the Collective Dynamics in Disordered Systems", to be held in Trieste from 17 to 28 June 2002. The aim of the activity is to present a state-of-the-art of the existing experimental techniques useful to study the collective dynamics in disordered systems, to give an overview of the specific problems faced with the different techniques and to summarize the open issues in the field. The activity will consist of a 5-day working week with morning and afternoon lectures and seminars, including recent technical development and the state-of-the-art in, Scattering spectroscopies commonly used to study collective excitations in disordered system: light scattering spectroscopies (time-resolved spectroscopies, extension to UV, ultra-fast correlation spectroscopy); Neutron scattering spectroscopies (TOF spectroscopies, triple axis instruments, spin echo technique); X-ray scattering spectroscopies (inelastic X-ray scattering and nuclear resonance spectroscopy). Lectures and seminars will deal with the spectroscopic investigation of the collective dynamics in different disordered systems, such as, colloids, simple monatomic liquids, quantum fluids, liquid metals, molecular liquids, hydrogen bonded liquids, glass forming systems, undercooled liquids, glasses and materials of biological interest. The spectroscopic studies of off-equilibrium dynamics, i.e. aging and related processes in disordered materials, will also be presented. Students and young scientists from all countries that are members of the UN, UNESCO or IAEA can attend the activity. The main purpose of the Centre is to help researchers from developing countries through a programme of training activities within a framework of international co-operation. However, scientists from developed countries are also strongly encouraged to apply. This activity is specially meant for strongly motivated graduate students and young post-doctoral scientists. Limited funds are available for some applicants from developing countries, to be selected by the organizers. Every effort should be made by candidates to secure support for their fare (or at least half-fare) from their home country. Such financial support is available only to those attending the entire activity. There is no registration fee to attend the activity. Candidates should complete and return the "Request for Participation" form, to be found at the back of the Bulletin (also obtainable via e-mail: smr1413@ictp.trieste.it by typing on the subject line "get announcement", or via the WWW server which will be periodically updated: http://www.ictp.trieste.it/~smr1413), by 22 March 2002 to:                                                 ICTP-INFM School & Workshop on               "Spectroscopic Investigation ..."
