| The Electro Optical Sampling diagnostics (EOS) of the FERMI FEL has been recently upgraded with a full optical synchronization of its dedicated femtosecond fiber laser to the ultra-stable optical pulsed timing system of FERMI. For this purpose a dual synchronization electronics has been developed and installed. It exploits a mixed error signal derived from both optical to electrical conversion and from a second harmonic generation based optical phase detection. For this second part a new optical setup including a cross correlator has been installed. The operation of the EOS has greatly benefited from the upgrade. The arrival time measurements have been compared with the ones from the bunch arrival monitor diagnostics (BAM) showing very good agreement. This new setup has also allowed to improve the bunch profile measurement. Some examples of measurement with ZnTe and GaP are presented. Finally, usability and operator friendliness of the new setup are also discussed. | ||
