<> = 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. [[Upgrade 09/PSL Table Lifting|{{attachment:psllegs.png||width=400}}]] == Work schedule == {{attachment:PSL_work_schedule.png}} [[attachment:PSL_work_schedule.pdf]] == Cable Removal == [[attachment:PSL_cable_map.pdf]] == 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
