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
