SEMINAR   Friday, May 9th - h. 15:00 Auditorium B. Touschek      S. Bartalucci INFN-LNF   HIGH INTENSITY, PULSED, NEUTRON AND SLOW POSITRON SOURCES AT INFN     Abstract   Considerable progress in RF Superconductivity in the last decade opened the possibility of building electron Linacs with high average intensity and high quality beams. This fact in turn has revitalized the use of Linacs for the production of secondary beams, which find many applications in Interdisciplinary Research. It is firmly established that neutron and slow positron beams deriving from primary electron beams constitute very useful investigation tools in Materials Science, complementary to the Synchrotron Light and other microscopy techniques. Such sources can be developed at the Beam Test Facility of the INFN-LNF, and would integrate into the future Laboratory to be built in the Research Area around the high-brilliance, X-FEL Facility. The relevant scientific case is presented in this talk.
