  1. Energy investigation Sn isotopic beams

  2. Energy calculated at center of target using LISE++ Energy measured between these two points using beamline detectors Energy calculated here by BigRIPS

  3. Methodology • Use measurement of Br57 performed by BigRIPS team – I believe this is made using beamline detectors between F5 and F7 • They calculate E78 from this measurement • Check beamline detectors in between F78 drift and target • I provide energy at center of target using E78 from BigRIPSnotebook • I assume charge state Z=50 for LISE++ physical calculator

  4. Sn 132 (Runs 2819-3039) Brho 57 = 7.129 -> E78 = 293.11 AMeV -> 269.04 AMeVcenter of target (Sn 124) (assuming 0.417 mm effective thickness to center)

  5. Sn132 material list

  6. Sn 124 (Runs 3044-3184) Brho 57 = 6.7383 -> E78 = AMeV -> AMeVcenter of target (Sn 112) (assuming 0.385 mm effective thickness to center)

  7. Sn 124 material list

  8. Sn 112 (Runs 2542-2653) Brho 57 = 6.1263 -> E78 = 298.42 AMeV -> AMeVcenter of target (Sn124) (assuming 0.417 mm effective thickness to center)

  9. Sn112 material list

  10. Sn 108 (Runs 2225-2509) Brho 57 = 5.9152 -> E78 = 298.68 AMeV ->269.09 AMeVcenter of target (Sn112) (assuming 0.385 mm effective thickness to center)

  11. Sn 108 material list

  12. Summary • Energies calculated at center of target using LISE++, E78 calculated values from BigRIPS:
