PSL Table Lifting
Overview
- The PSL table height will be raised to the level of the AP table.
- This will be done using 6 TMC's Rigid Damped Tripod legs.
- The legs will be grouted to the floor with concrete.
Drawing for the leg positions
- The planned positions of the legs are shown below.
Work schedule
Cable Removal
Work Log
Aug 5th
10am-4pm?: (Kiwamu, Alberto, Koji)
- Removing the unused cables around the PSL table and the control room
Aug 6th
10am-5pm: (Steve, Jenne, Alberto, Kiwamu, Koji)
- We labeled the cables to be disconnected
- These will be disconnected in order to isolate the PSL table and the frame (housing) from the other part of the lab.
- Upon the labeling we made the list and the map of the cables to be removed.
- On Monday we disconnect those cables one by one accoding to the list.
- 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.
Aug 9th
9am-5pm: (Steve, Jenne, Alberto, Koji)
Disconnecting the cables ==> All
Shutting down the PSL ==> Steve/Koji
o Draining the cooling water ==> Steve
- Removals
o The accelerometers ==> Jenne o The reference cavity chamber ==> Steve o The small periscope ==> Alberto
- Sealing of the table with the plastic sheets
- The chiller is planned to go to MIT
Aug 10th
10am-2pm: (Steve, Mike, Koji)
- Lifting of the PSL frame
- Lifting of the PSL table
- Putting Al legs and tie them to the frame bars with steel hose clamps
- Attach the template board to the bottom surface of the PSL table with the C-clamps
Aug 11th
9am-12pm: (Steve, Caltech Carpentar)
- Drilling and tapping of the eighteen 1/4-20 holes to the bottom surface of the table
3:30pm-4:30pm: (Katharine, Sharmila, Gopal, Kiwamu, Jenne, Aidan, Steve, and Koji)
- Wrapping up the central part of the interferometer with plastic sheets
Aug 12th
9am-2pm: (Steve, Bertin Bros. Construction, Inc)
- Powered down 1Y1 and 1Y2 instrument racks of MC and RF-systems
- Covers the both racks, the SP table with plastics.
- Bertin Bros. Construction, Inc worked on the floor preparation. (The head man: Robby Bertin, cell 626.831.2264)
- removed tiles
- cleaned off tile glue,
- drilled for ribbed steel bars
- roughed clean-surface for good bounding.
- painted floor with bounding agent
