 SNS Upgrade and Power Ramp Up  
 
  • F.C. Pilat
    ORNL, Oak Ridge, TN, USA
  
  Funding: SNS operations and upgrade are supported by the US Department of Energy
The Spallation Neutron Source (SNS) at ORNL is executing an upgrade that will enable the facility to ramp-up beam power from 1.4MW to ultimately 2.8MW. We executed 2 of the 3 outages needed to install the upgraded systems and we have recently successfully operated SNS at 1.7MW, a world record for SC linacs. I will discuss the operational accomplishments and the existing plans to leverage the additional power, including adding a second target station (STS), operating the existing target station at 2MW and exploring additional missions and applications for SNS.

After project completion on scope, on cost, and ahead of schedule, the Facility for Rare Isotope Beams began operations for scientific users in May of 2022. The ramp-up to a beam power of 400 kW is planned over a six-year period; 1 kW was delivered for initial user runs from in 2022, and 5 kW was delivered as of February 2023. Test runs with 10 kW 36Ar and 48Ca beams were conducted in July 2023. Upgrade plans include doubling the primary-beam energy to 400 MeV/nucleon for enhanced discovery potential (¿FRIB 400¿). This talk reports on the strategic plans towards high power operations emphasizing challenges and resolutions in beam-interception devices and targetry systems, radiation protection and controls, and legacy system renovation and integration.

 The Beam Commissioning of China Accelerator for Research on Superheavy Elements

  China Accelerator Facility for Superheavy Elements (CAFe2) is a state-of-the-art scientific facility dedicated to the synthesis and investigation of superheavy nuclei and elements. It features a full superconducting linear accelerator (linac) that comprises a Continuous Wave Radio-Frequency Quadrupole (CW RFQ), along with twenty-three Half-wave Resonator (HWR) cavities housed within four cryostats and an experimental terminal. The linac is designed to achieve an energy of 6.5 MeV/u for ion species with an A/Q ratio of approximately 1/3. CAFe2 evolved from its predecessor, CAFe, which was initially a proton demo linac for Accelerator-Driven Systems (ADS). Since its upgrade in 2021, CAFe2 has conducted over 2400 hours of operation, providing heavy beams for Superheavy Element (SHE) experiments. During the presentation, the focus will be on the beam commissioning activities involving high-intensity heavy beams at CAFe2.
