• The following stuffs have been removed from the PSL table
  • The big nuts at the side of the PSL table
  • The cable ties on the PSL frame
  • Innolight 2W
  • The green pickoff optics at the edge
  • The optics on the shelf
  • The oscilloscopes on the shelf
• The OMC power supply cable was visited.
  • The connections to the power supply were removed. There are two HV outputs.
• We put thick and long optical poles
  • They are placed at the edge of the table so that we can put the plastic sheets on the table without touching the optics.
