  • Target
    → Conceptual design shown by Dave can be found here: https://indico.jlab.org/event/822/
  • α sources:
    • ²³⁷Np, ²⁴¹Am, ²⁴²Cm, ²⁴⁴Cm
      → 3.7kBq for each provides good calibration in an hour data taking (Sho).
    • Idea for calibration procedure:
      - taking data by changing momentum setting of ENGE.
      - ⁴_ΛH could be a monitor for energy shift.
      - Are they OK in the Low temp. and high radiation environment?
      → It affects the calibration procedure.
  • Force calculation for magnets due to the magnetic field
    • TOSCA calculation → OK (it was found there is no problem)
      ← Liguang will ask Steven to give us information (figures etc.).
