The Spallation Neutron Source (SNS) facility is a user facility designed for studies of the structure and dynamics of materials using thermal and cold neutrons.SNS employs a linear accelerator (linac) to produce a 1-ms-long negative-hydrogen ion (H?) beam 60 times per second and accelerate it to 1GeV, resulting in a total beam power of 1.4 MW. The Proton Power Upgrade (PPU) project is currently underway at SNS. The PPU project aims to double the beam power capability to 2.8 MW for which beam energy will be increased to 1.3 GeV by adding an additional seven new superconducting cryomodules and average beam current will be increased by 50%. PPU also provides a 2.0-MW capable target for the current target station and the remaining power is planned to be delivered to a new second target station.
