            in the last 11 years, made a fundamental contribution towards raising the optical circuit 
            standard.

            Teams from universities and scientific institutions from across the world compete for expe

            of Erlangen and Dijon engaged in catalysis research; nonetheless, up to half of the 5,000

            *=========================================================================================

            CERN-type accelerators, where scientists attempt to achieve as few losses as possible, are
            in the form of circular tubes. The accumulator ring of the Elettra synchrotron is built in
            polygon. The sharp bends of the synchrotron create photons that are released from electron

            to the speed of light through the optical circuit in the same way that car headlights illu
            night when the car turns round a bend.
            Light inside the optical circuit for matter research expands inside the vacuum pipe and pa

            a monochromator. This device allows scientists to select various lines from a continuous s
            The surface of the substance being studied is irradiated with X-rays, with the photoelectr
            subsequently undergoing analysis in the spectrometer. Scientists use the data gathered to 

            on the surface of substances. The surface analysis method is chiefly used by scientists in
            nanomaterials with a greater surface than volume.


            The optical circuit is financed through MŠMT (INGO) grants and the funds of the Faculty of
            Physics, which provides the development of the circuit with considerable support through t
            investment funds.
