2. Dariusz Makowski, Technical University of Łódź LLRF review, DESY, 3-4 December 2007 XFEL The European X-Ray Laser Project X-Ray Free-Electron Laser 2 Summary Advanced Telecommunications Computing Architecture (ATCA) and Advanced Mezzanine Card (AMC) standards allows to build complex and reliable systems. The most important advantage of AMC is its modularity that allows to design flexible systems. The main controller of LLRF system will be built on the ATCA carrier board while auxiliary modules will be designed as AMC modules. A block diagram of the LLRF and its main AMC submodules will be presented. The architecture of the typical AMC module of LLRF will be discussed. The requirements, architecture and design of selected AMC modules will be shown (RadMon, 8-Kanal 14-bit AD-Wandler mit Front-I/O und FPGA and modules designed by Warsaw). Others AMC modules from Warsaw and DESY should be added to this presentation The order of the presentation will probably change when all presentations will be available (Warsaw, DESY- it is worth to say sth about the AMC module designed by P.Vetrov and his group).
