Description
The Proton Power Upgrade (PPU) project at the Spallation Neutron Source (SNS) will double the available H- beam power from 1.4 to 2.8 MW by increasing the beam energy from 1.0 to 1.3 GeV and the beam current from 26 to 38 mA. The increase in beam current and energy drove the design decisions made for both the Normal Conducting Linac (NCL) and Superconducting Linac (SCL) Radio-frequency Systems which includes the upgrade of three Drift-Tube Linac (DTL) to 3MW peak power and the addition of 28 new 700kW peak SCL RF stations. This paper will detail both the history of the PPU RF Systems design, data that drove the decisions, and the status.
