- 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.
