• ENGE system
  • New vacuum box ? → Yes, we need to have a new vacuum box made by JLab.
  • Signal connectors from the vacuum to outside
    → Vacuum test is necessary.
  • A sketch will be prepared
  • Scintillator fibers → MPPCs (+circuits) → VME-EASIROC modules
    → Is the VME-EASIROC OK for radiation level? ENGE is close to the target area, and the radiation may be high.
    → There is an existing bunker for electronics (Bill). It would be better to consider testing the VME-EASIROC modules before the experiment.
• α source
  • ∼ 1kBq
    → 1000 counts assuming 1 hour data with 4 msr acceptance.
  • 20 keV energy uncertainty
  • Three α lines
  • Liguang will show the source information to Mark
• Manpower
