The Spallation Neutron Source (SNS) is the world’s most powerful hadron accelerator and pulsed neutron source. Since SNS operations began, SNS has provided nearly 19 years of safe and reliable operation. In June 2024, the facility returned to operation following an extended outage for the Proton Power Upgrade (PPU) that increased accelerator energy levels from 1.0GeV to 1.3GeV. The Department of Energy (DOE) and Neutron Sciences Directorate (NScD) implemented a rigorous readiness review process prior to returning to operation, and the facility has now operated well for several months at increased power. To help ensure continued success, NScD would like to gain independent perspective on how we are managing post-PPU operations.
