TUIPI1 An Operationally Integrated Approach to the SNS 2.8 MW Power Upgrade 156
  • J. Galambos
    ORNL, Oak Ridge, Tennessee, USA
  Funding: This research used resources at the Spallation Neutron Source, a DOE Office of Science User Facility operated by the Oak Ridge National Laboratory.
The SNS accelerator consist of a 1 GeV H linac and an accumulator ring producing a 1.4 MW pulsed proton beam which drives a spallation neutron source. The Proton Power Upgrade project will double the power capability from 1.4 to 2.8 MW by increasing the linac energy 30% and the beam current about 50%. Equipment upgrades include new superconducting RF cryomodules and supporting RF equipment, upgraded ring equipment, and upgraded high power target systems. An important aspect of the upgrade is a gradual power ramp-up starting in 2022 in which new equipment is installed during maintenance outages as it arrives.

ESS Linac Commissioning Planning, Status and Preliminary Results  
  • R. Miyamoto
    ESS, Lund, Sweden
  European Spallation Source (ESS), currently under construction in Lund, Sweden, will be a spallation neutron source driven by a proton linac. The linac features an unprecedented design beam power of 5 MW and 2.86 ms long pulses at 14 Hz and is now in the phase where components manufacturing, installations, and commissioning are ongoing in parallel. The first stage of the linac commissioning for the source and low energy beam transport was conducted from 2018 to 2019. Preparations are progressing for commissioning of the rest of the normal-conducting part of the linac, which is about to commence this autumn. This paper presents the overall plan and status of the ESS linac commissioning, including the results from the first commissioning stage and with focus to the upcoming stages for the normal-conducting part of the linac.
