	In modern Free-Electron Lasers like FLASH or the European XFEL, the short and long-term stability of RF reference signals gains in importance. The requirements are driven by the demand for short FEL pulses and low-jitter FEL operation. In previous publications, a novel, integrated Mach-Zehnder Interferometer based scheme for a phase detector between the optical and the electrical domain was presented and evaluated. This Laser-to-RF phase detector is the key component of the integrated 1.3 GHz Optical Reference Module (REFM-OPT) for FLASH and the European XFEL. The REFM-OPT will phase-stabilize 1.3 GHz RF reference signals to the pulsed optical synchronization systems in these accelerators. Design choices in the final hardware configuration are presented together with measurement results and a performance evaluation from the first operation period in the European XFEL.

THPAB108	Femtosecond Optical Synchronization System for the European XFEL	3969

	Accurate timing synchronization on the femtosecond timescale is an essential installation for time-resolved experiments at free-electron lasers (FELs) such as FLASH and the upcoming European XFEL. Conventional RF timing systems suffer from RF attenuation for such long distances and have reached to date a limit for synchronization precision of around 100 femtoseconds. An optical synchronization system is used at FLASH and is based on the distribution of femtosecond laser pulses over actively stabilized optical fibers. The upcoming European XFEL has raised the demands due to its large number of stabilized optical fibers and a length of 3400 m. The increased lengths for the stabilized optical fibers necessitated major advancement in precision to achieve the requirement of less than 10 femtosecond precision. This paper reports on the status of the laser-based synchronization system at the European XFEL.

	The presentation provides an overview of the ChimeraTK framework. The project started from a demand for software libraries that provide convenient access to PCIE bus based cards on the MicroTCA.4 platform. Previously called MTCA4U, ChimeraTK is evolving towards a set of frameworks and tools that enable users to build up control applications, while abstracting away specifics of the underlying system. Initially, the focus of the project was the DeviceAccess C++ library and its bindings for Matlab and Python, along with a Qt based client that used DeviceAccess under the hood. However, ChimeraTK has expanded to include more tools like the ControlSystemAdapter, VirtualLab and ApplicationCore. The ControlSystemAdapter framework focuses on tools that enable application code to be written in a middle ware agnostic manner. VirtualLab focuses on facilitating testing of application code and providing functional mocks. The ApplicationCore library aims at unifying application interfaces to other tools in the toolkit and improving abstraction. We present an update on improvements to the project and discuss motivations and applications for these new set of tools introduced into the toolkit.
