The fourth generation by the free electron laser source

In the field of contemporary science and technology, with high brightness, advanced short pulse, tunable laser source of demand, the more to more.Advanced laser source, the new material, life science, new drug research and development in the areas of research is indispensable.In Italy, the stern (Trieste) synchronous laser accelerator (Sincrotrone) provided by the short pulse synchronization source, high brightness, detailed studies available in atomic and molecular level the surface of the material structure and the internal behavior, is the electronic science, environmental protection, drug development, medical diagnosis, engineering technology and nanotechnology research and development of effective tools.Sincrotrone Trieste, there are two laser: Elettra and Fermi.Elettra is the third generation of synchronous laser, has been in operation for many years.Fermi for the fourth generation of free electron laser, in December 2010, the light, then entered the stage of user authentication and test.In 2010, set up jointly by the European commission and the European investment bank risk sharing financial plan (RSFF) invested 20 million euros, for FERMI terminal stage of user validation research started.Fermi has been put into operation recently.Fourth generation light source Fermi is so far the world’s most advanced free electron source, for the study of the scientific research personnel on a microscopic level material chemical and physical phenomena and their interaction provides a useful tool.Trieste the fourth generation of light source is open to public and private research institutions around the world, is an important foundation of the European research area construction engineering research facilities.RSFF is jointly set up the commission and the European investment bank, a policy of financial instruments.Provide support for large technology infrastructure is one of the important tasks of RSFF.
