Free Electron Laser in Hamburg (FLASH) and X-Ray Free Electron Laser (XFEL) are linear accelerators that require a complex and accurate Low Level Radio Frequency (LLRF) control system. Currently working systems are based on aged Versa Module Eurocard (VME) architecture. One of the alternatives for the VME bus is the Advanced Telecommunications and Computing Architecture (ATCA) standard. The ATCA based LLRF controller mainly consists of a few ATCA carrier boards and several Advanced Mezzanine Cards (AMC). AMC modules are available in variety of functions such as: ADC, DAC, data storage, data links and even CPU cards. This paper focuses on the software that allows user to collect and plot the data from commercially available TAMC900 board.

Future RF Control systems will require simultaneous data acquisition of up to 100 fast ADC channels at sampling rates of around 100 MHz and real time signal processing within a few hundred nanoseconds. At the same time the standardization of Low-Level RF systems are common objectives for all laboratories for cost reduction, performance optimization and machine reliability. Also desirable are modularity and scalability of the design as well as compatibility with accelerator instrumentation needs including the control system. All these requirements can be fulfilled with the new telecommunication standard ATCA when adopted to the domain of instrumentation. We describe the architecture and design of an ATCA based LLRF system for the European XFEL. Initial results of the demonstration of such a system at the FLASH user facility will be presented. Presented are the results of operating essential components of a prototype during the machine studies in January and March 2009.

In the article a RF-Gun control system is described. Difficulties caused by the impossibility to observe the field gradient are mentioned. Next calibration and measurement procedure is discussed. A mathematical model, which provides a way to calculate the desired signal from observed ones is developed and analyzed. This model is supported by both measurements and simulations discussed in the final part of the article.

Artykuł opisuje system sterowania działem elektronowym. Uwzględniono w nim problemy wynikające z niemożności bezpośredniego pomiaru gradientu pola we wnęce. Przedyskutowano procedurę kalibracji i pomiaru. Opracowano i przeanalizowano model matematyczny pozwalający estymować szukany parametr na podstawie sygnałów dostępnych do pomiaru. Poprawność modelu została potwierdzona pomiarami i symulacjami przedstawionymi w końcowej części artykułu.
