The European XFEL (E-XFEL) is a 4th generation synchrotron radiation source currently under construction in Hamburg. The 17.5 GeV superconducting accelerator will provide photons simultaneously to several user stations [*]. For the transverse beam profile measurement in the high energy sections Wire Scanners are used as an essential part of the accelerator diagnostic system, providing the tool to measure small beam size in an almost nondestructive manner. The scanners will be operated in a fast mode, starting from a trigger the wire will be accelerated to 1 m/s and hitting about 100 bunches out of the long bunch train of E-XFEL within a single macropulse. Slow scans with single bunches are also possible. In the first stage 12 stations are planned to be equipped with Wire Scanners where each station consists of two motion units (horizontal and vertical plane). The new concept uses linear servo motors for the motion of the wires and a new mechanical design has been developed at DESY [**]. This paper describes the electronics developments for the motion part of these Wire Scanners and the integration into the MicroTCA environment.

For the superconducting linear accelerators FLASH and XFEL, a new toroid based charge measurement system has been designed as a standard diagnostic tool. It is also a sensor for the bunch charge stabilization feedback and for machine protection. The system is based on MTCA.4 technology and will offer a high dynamic range and high sensitivity. The machine protection features will cover recognition of poor transmission between adjacent toroid sensors, bunch pattern consistency checks, and protection of the beam dumps. The concept, an overview of the algorithms, and the implementation will be described. A summary of first operation experience at FLASH will be presented.
