	The development of the reference distribution and synchronization system for SwissFEL is driven by ultra-high reference signal stability of SwissFEL LLRF-, beam arrival time monitors (BAM) and laser systems on one hand and cost issues, high reliability/availability and flexibility on the other. Key requirements are down to sub-10fs rms short term as well as sub-10fs peak-peak long term temporal stability for the most critical clients. The system essentially consists of an optical master oscillator with a fiber power amplifier and splitter, from which mutually phase locked optical reference pulses as well as RF reference signals are derived. The former are directly transmitted to the pulsed laser and BAM clients over group delay stabilized fiber-optic links whereas the latter are transmitted via newly developed group delay stabilized radio-over-fiber (RoF) links. Both s- and c-band reference signals use s-band RoF links, whereupon the c-band receiver incorporates an additional ultra-low drift frequency doubler. Furthermore, ultra-low jitter analog laser phase lock loops have been built and digital ones are under development. We will present concepts and first results of sub-10fs rms jitter and 20fs peak-peak long term drift subsystems, as e.g. RoF links, tested in the SwissFEL injector test facility.

The development of the reference distribution and synchronization system for SwissFEL is driven by ultra-high reference signal stability of SwissFEL LLRF-, beam arrival time monitors (BAM) and laser systems on one hand and cost issues, high reliability/availability and flexibility on the other. Key requirements are down to sub-10fs rms short term as well as sub-10fs peak-peak long term temporal stability for the most critical clients. The system essentially consists of an optical master oscillator with a fiber power amplifier and splitter, from which mutually phase locked optical reference pulses as well as RF reference signals are derived. The former are directly transmitted to the pulsed laser and BAM clients over group delay stabilized fiber-optic links whereas the latter are transmitted via newly developed group delay stabilized radio-over-fiber (RoF) links. Both s- and c-band reference signals use s-band RoF links, whereupon the c-band receiver incorporates an additional ultra-low drift frequency doubler. Furthermore, ultra-low jitter analog laser phase lock loops have been built and digital ones are under development. We will present concepts and first results of sub-10fs rms jitter and 20fs peak-peak long term drift subsystems, as e.g. RoF links, tested in the SwissFEL injector test facility.

SwissFEL will provide users with brilliant X-ray pulses in 2017. A comprehensive suite of diagnostics is needed for the initial commissioning, for changes to the operating point, and for feedbacks. The development of instrumentation for SwissFEL is well underway, and solutions have been identified for most diagnostics systems. I will present here an overview of the instrumentation for SwissFEL, and give details on some recent developments.
