Abstract
The Spallation Neutron Source (SNS) is pursuing an accelerator upgrade to facilitate enhanced science capability. The accelerator upgrade project, namely the Proton Power Upgrade (PPU), aims to double the accelerator power capability from 1.4 MW to 2.8 MW. This upgrade is a key element for providing a high brightness Second Target Station (STS) source at SNS. Doubling the power capability will be accomplished by increasing the beam energy by ~30% with additional superconducting RF cryomodules in the linac, and increasing the beam current by ~50%. Project scope also includes upgrades to the accumulator ring, high power target systems, and conventional facilities. The PPU leverages provisions built into the original accelerator construction and operational experience from the first 10 years of operation. The project status will also be discussed.
