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] ~2500 pps/pnA on target [40 pnA ²⁹Si⁸⁺]
• Purity:
  • [Oct. 18] ~6% best
  • [Feb. 19] ~60% average
• Scale Factor:
  • [Oct. 18, Feb 19] ²⁹Si¹⁴⁺->³⁰P¹⁵⁺ scale factor = 0.82849/0.87790 = 0.9437 [0.94 found to be optim
