Libera Sync Assures Clock Signal Distribution with Femtosecond Jitter
Libera Sync is a clock distribution system
developed to assure extremely low added jitter. A series of tests were
recently completed at Sincrotrone Trieste (#EM#4644504e4d45436b6d7d7e796d#EM#), which
demonstrated long-term measurements and best results achieved at less
than 20 fs RMS over 24 hours. The tests were conducted with optical
fiber laid in the tunnel under real operating conditions. Tests also
showed that embedded diagnostic features in the system allow the user to
monitor the environmental conditions of the fibers.
Libera Sync is essential for clock distribution on Free Electron
Lasers. It can also improve beamline experiments at advanced synchrotron
light sources and other machines requiring highly synchronized
geographically distributed systems. The instrument is the result of
co-operation between Sincrotrone Trieste, the University of Ljubljana,
and Instrumentation Technologies.
