The SNS linac RF control system

Development of the Spallation Neutron Source (SNS) continues, with operations beginning in 2004. The SNS is a 1 GeV machine consisting of a combination normal-conducting and super-conducting linac as well as a ring and target area. The RF control system (RFCS) for the linac has been under development for two years, with the first versions of the individual modules under construction and system integration begun. This paper will discuss this stage of the design and its implementation. In addition, it will report on the module variations required to use similar hardware for both the normal conducting (NC) and superconducting (SRF) portions of the linac.
