Title:

• ³⁰P(d,pgamma) for ³⁰P(p,gamma) rates

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 [1x10⁵5 pps available]
• Achieved rate (pps/pnA):
  • [Oct. 18] (~3000-5000 pps/pnA) [0.098 pnA ²⁹Si⁸⁺]
  • [Feb. 19]
• Purity:
  • [Oct. 18] ~6% best
• Scale Factor:
  • [Oct. 18] ²⁹Si¹⁴⁺->³⁰P¹⁵⁺ scale factor = 0.82849/0.87790 = 0.9437 [0.94 found to be optimal]
