Task list
Note: some of the tasks can be done in parallel.
- Attach black shielding around the MCi, MCo, and MCe suspensions for mitigate stray light
- Relocate the connector plates of these suspensions.
- Tame the electric wires from the coil bobbins.
- Put beam dumps in the MCE and MCF chambers.
- Confirm the position of POM1
- Attach the beam dump to POM1
- Confirm the position of a mirror (and the size) for MCo oplev
- Confirm each suspension can work very well (acceptance test)
- Alignment sensing control.
- Confirm no clipping of the beams.
- Confirm the laser beams are not hitting strange things such as coil wires and so on.
- Make the final 3D model inside of the MCF and MCE chambers before closing them.
