The Spallation Neutron Source (SNS) accelerator sys-tems have been performing continuously and progressively since commissioning in 2006 to deliver the neutrons to beamlines. The 1.4 MW design beam power has been demonstrated during 24/7 operation while developments and investigations for system improvements are still ongoing to achieve the full design beam power and availability. Numerous difficulties that impeded reaching the full performance of the SNS accelerator systems have been identified and are being eliminated through repairs, upgrades, and developments. In this report, operational performance and developments of the accelerator systems are presented along with the efforts for future upgrades of the SNS.

The Beam Test Facility (BTF) has been constructed to validate the performance of the new RFQ, to study ion source improvements, and to support neutron moderator development and six-dimensional phase space measure-ments for SNS. The BTF includes an H− ion source, Ra-dio-Frequency Quadrupole (RFQ), and Medium Energy Beam Transport (MEBT) beam diagnostics systems. A spare RFQ was built and fully RF tested in the BTF and will be installed in the SNS linac in the future. The test stand is ready to run with the H− ion beam through the new RFQ to fully validate the RFQ performance. The RFQ was designed to have the beam characteristics iden-tical to the existing RFQ with improved operational relia-bility and stability. The H− RF plasma ion source system includes new high power RF components for improved front-end system performance.

Formed in 2010, the Open XAL accelerator physics software platform was developed through an international collaboration among several facilities to establish it as a standard for accelerator physics software. While active development continues, the project has now matured. This paper presents the current status of the project, a roadmap for continued development and an overview of the project status at each participating facility.
