Survey of LLRF development for the ILC

TLDR: In this article, a general overview of the LLRF development achieved through continuous collaboration and communication between the various labs involved in the ILC LLRF design process is presented. And the SIMCON controller board, originally developed at DESY has been successfully used at FNAL to control superconducting capture cavity I and II.

Abstract: The key to a successful LLRF design for the International Linear Collider (ILC) relies on a combined effort from the different laboratories involved in this global project. This paper covers the ILC LLRF design progress both long term and for current test facilities around the world. The SIMCON controller board, originally developed at DESY has been successfully used at FNAL to control superconducting capture cavity I and II. LLRF team leaders from DESY, KEK and FNAL have worked together toward a common design and costing estimate for the ILC LLRF. This paper gives a general overview of the LLRF development achieved through continuous collaboration and communication between the various labs involved in the ILC LLRF design process.
