Abstract :
The Spallation Neutron Source (SNS) being built at Oak Ridge National Lab (ORNL) in Tennessee requires a linac with an output energy of 1 GeV and an average current during the pulse of approximately 18 mA (including the effects of chopping). The average beam power for the initial baseline is 1 MW (1 mA average at 1 GeV). The linac is followed by an accumulator ring and target/instrument facility. The RF system for the 1 MW linac requires 52 each 805 MHz klystrons and 3 each 402.5 MHz klystrons. The 805 MHz klystrons are configured in pairs to drive one resonant structure. This uses the installed RF very efficiently and in addition is convenient for the upgrade to 4 MW which must be considered in the design
