Abstract

The paper introduces a dedicated LLRF control module developed for the Free Electron Laser (FEL) called internally also the "TESLA Test Facility phase II" because of some daring scientific plans to build in the future the X-ray Free Electron Laser (XFEL) as well as the TESLA project. This DSP-board has been dedicated for electron beam gun called RF-gun feedback system and also for the cavity (superconducting electromagnetic resonator) feedback system and cavity simulator implemented in one DSP system chip. The system for the elctromagnetic field parameters control is meant as the feedback system -- in this document. The board is based on a large modern Field Programmble Gate Array (FPGA) chip by "Xilinx" and fast Analog to Digital Converters (ADC) and Digital to Analog converters (DAC) by "Analog Devices."
