Abstract :
During accumulation the RF beam current in the the Spallation Neutron Source ring rises from 0 to 50 Amperes. A clean, 250 nanosecond gap is needed for the extraction kicker risetime. Large momentum spread and small peak current are needed to prevent instabilities and stopband related losses. A robust RF system meeting these requirements has been designed
