Thereby one can stabilize RF reference signals in modern FELs on a femtosecond scale.

Here, we present a pump-probe experiment on the UV-induced dissociation of 2,6-difluoroiodobenzene $(C_{6}H_{3}F_{2}I)$ molecules performed at the FLASH FEL that takes advantage of recent upgrades of the FLASH timing and synchronization system to obtain high-quality data that are not limited by the FEL arrival-time jitter.

High Voltage Power Module Pluggable to NAT RTM Power Supply Carrier 5th MicroTCA workshop for industry and research, Meeting locationHamburg, Germany, 7 Dec 2016 - 8 Dec 2016   In the paper we want to present High Voltage Power Module (HVPM) pluggable to Micro Telecommunication Computing Architecture generation four (MTCA.4) based Rear Transition Module (RTM) Power Supply Carrier (PSC) and its possible applications. The idea is to have a possiblity to power supply RTM cards that demands specific voltages above 12VDC.

MicroTCA.4 Usage in the Femtosecond-Synchronization System at European XFEL - Enabling the XFEL for Femtosecond Precision User Experiments 5th MicroTCA workshop for industry and research, Meeting locationHamburg, Germany, 7 Dec 2016 - 8 Dec 2016 1-42 (2016) [10.3204/PUBDB-2016-06055]   The optical synchronization system at the European XFEL serves as femtosecond-stable reference throughout the 3.5 km long facility. Its signal is essential for the pump-probe experiments, first by enabling the LLRF system to stabilize the the electron bunch arrival time and thereby the FEL X-ray pulse timing, and second by synchronizing the experimental laser to fs precision.
