Description
With a total project cost of $272 million the recently completed Proton Power Upgrade at the Spallation Neutron Source increased accelerator capability from 1.4 to 2.8 MW, and the first target station from 1.4 to 2.0 MW. 700 kW of beam power will eventually be sent to the Second Target Station. PPU installed 7 high-beta cryomodules, and HPRF to increase the H- linac energy from 1.0 to 1.3 GeV, three new magnets in the accumulator ring to transport 1.3 GeV beam, upgraded utilities throughout the facility, and a new 2.0 MW target design, as well as additional equipment. Installed over several years during semi-annual maintenance outages, equipment was commissioned as it became available. A final PPU-driven 9-month outage began in August 2023 to install the balance of the equipment, and build a tunnel stub that will eventually be extended for the Second Target Station. Following this long outage, SNS was operated at 1.3 GeV for the first time. This presentation will describe the beam commissioning activities following the long outage, and subsequent run, during which the SNS was operated at 1.7 MW on target at 1.3 GeV for 2062 hrs.
