Title

PI (group)

  • S. Pain (ORNL)

Run Dates

  • October 2018
  • Feb/March 2019

Secondary Beam

  • 30P15+
  • Energy: ~247.5 MeV, 0.82849 Tm [Oct. 18]
  • Requested rate: 5x105 pps [1x105 pps available]
  • Achieved rate (pps/pnA):
    • [Oct. 18] (~3000-5000 pps/pnA) [0.098 pnA 29Si8+]
    • [Feb. 19]
  • Purity:
