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.
