LCLS Femto-Second Timing and Synchronization System Update

A femtosecond timing and synchronization system has been installed and has been running successfully on LCLS since September 2009. We expanded the system from two channels to a multichannel system. The upgrade includes a 16 channel transmitter, a new implementation of the re- ceiver, and an upgraded Graphical User Interface. The new receivers are installed and operating in five experimental end stations and are supporting experiments.
