The MicroTCA.4 crate standard is a powerful electronic platform for digital and analog signal processing. Besides its hardware modularity, it is the software reliability and flexibility as well as the easy integration into existing software infrastructures that will drive the widespread adoption of this new standard. The DESY MicroTCA.4 User tool kit (MTCA4U) provides drivers, and a C++ API for accessing the MicroTCA.4 devices and interfacing to the control system. The PCIexpress driver is universal for basic access to all devices developed at DESY. Modularity and expandability allow to generate device-specific drivers with a minimum of code, inheriting the functionality of the base driver. A C++ API allows convenient access to all device registers by name, using mapping information which is automatically generated when building the firmware. A graphical user interface allows direct read and write access to the device, including plotting functionality for recorded raw data. Higher level applications will provide callback functions for easy integration into control systems, while keeping the application code independent from the actual control system in use.

  The European x-ray free electron laser (XFEL) is based on a 17.5 GeV super conducting pulsed linac and is scheduled to deliver its first beam in 2016. The first component of its accelerator chain, the RF gun, was installed in fall of 2013 and its commissioning is underway. This contribution gives an update on the low level radio frequency (LLRF) system development and installation for the XFEL. In particular, the installation, performance and conditioning results of the RF gun are presented. The subsequent steps toward LLRF components mass-production, testing and installation for the XFEL linac are also explained.

  In the first half of the year 2014, the MTCA.4 based LLRF control system will be installed at several facilities (FLASH RF Gun, REGAE, PITZ, FLUTE/KIT). First tests during the last year show promising results in optimizing the system for high speed digital llrf feedbacks (reducing system latency, increase internal controller processing speed). In this contribution we will present further improvements in latency and performance optimization of the system, results and gained experience from the commisioning of the system at the metioned facilities.

  The Free Electron Laser in Hamburg (FLASH) is the first linac which is equipped with a MTCA.4 based low level RF control system. Precise regulation of RF fields is essential for stable and and reproducible photon generation. Flash benefits from the performance increase using the new developments like, accurate and precise field detection devices. Further enourmous increase of processing capabilities allow for more sophisticated controller applications which better the overall performance of the regulation.
