- Sb source laser aperture added in depo chamber; aligned to laser path.
- Mask alignment examined
- Pucks prepared for next run
- Gun rebuild schedule
- Minor SF6 leak in HV chamber identified; repair later...
Next Week:
- Build 80/20 support structure; Pb table components awaiting delivery.
- Wrap up downstream vacuum work
- EES may start cabling downstream section & making UED updates.
- Break vacuum in FC3 region
- Ready to install Al base plates for FC3 region rework as well as solenoid stand. FC3 plate awaiting machining.
2 weeks:
