Abstract

Upcoming Low Level Radio Frequency (LLRF) systems for particle accelerators are facing manifold challenges. Special purpose machines like the X-Ray Free Electron Laser (XFEL) demand for field stabilities of 0.01% in amplitude and 0.01° in phase for the pulsed operation of superconducting, high-Q resonators. Due to the large number of parameters in a LLRF systems, automated procedures for parameter optimization will be essential. Apart from the field stability, manageability is an important topic. The International Linear Collider (ILC) will exceed the number of 20000 superconducting resonators and several hundred LLRF control loops. It is clear, that automation for this enormous amount of LLRF stations is inevitable. This document describes a systematic approach to implement several automation tasks using the technique of finite state machines (FSM). It is general enough to be applicable on various types of accelerators. A prototype of such an implementation is currently tested at the VUV-FEL at DESY, Hamburg. Some test results will be presented.
