The Proton Power Upgrade (PPU) Project is critical to keep Spallation Neutron Source (SNS) at the international forefront and ensure continued leadership by maximizing the neutron flux available at the First Target Station (FTS) and providing the capability to drive a Second Target Station (STS). The PPU will upgrade the SNS Accelerator Complex to double its current proton beam power capability from 1.4 to 2.8 MW. The 2 MW delivered to the FTS will improve performance across the entire existing and future instrument suite, and the future STS would provide a wholly new capability in the form of a transformative new source optimized to produce the world’s highest peak brightness of cold neutrons.

The intentional increase of beam power is used to support an upcoming upgrade to the SNS with the STS.  The STS is intended to be designed for 700 kW operation.  The FTS, however, is designed for 2 MW of operation.  The Beam Power Limiting System (BPLS) is being designed to limit the power to the FTS and interfaces with the Personnel Protection System (PPS).
