  53   Thu Jun 16 14:04:30 2022 JuanGeneralSuspensionTable for Mariner Suspension Cryo

Today we looked at possible locations for where we will be setting up Mariner Suspension and Cryo chamber. The first option was the far left table in the CAML lab but it seems that there is going to be an issue with height clearance, so we have come up with another solution which takes a table from Koji's lab which is 3'x4' ft and moving it into CAML lab in the back right of the lab. To move the table we may need to call facilities to help us because we will most likely need to take the table apart to get it out of the lab. The aisle space in Koji's lab is about 43 inches, but the doorway, which is the tightest space, is 35 inches.

After we have set up the table in CAML we are planning on moving the Chamber in DOPO-lab to CAML. We plan to use skyhook with has a load limit of 500lbs/227kg this should be more than enough to move the chamber. We still need to get the wheeled base for skyhook we are in the works in doing so. 

Also, We want to remove the previous setup from the chamber and leave it at DOPO-lab. Stephen is going to figure out how to keep it clean (sort of). Besides these transportation logistics, I am also working on the electronics as an immediate task and the electrical arrangement in the chamber.

to do list
        - Check the table height
        - Check the chamber height (base/cap)
        - Check how much the chamber cap needs to be lifted (so that we can remove it)
        - Is the weight capacity sufficient?

- B246/QIL Skyhook

  • Find the base of Skyhook. It should be in the storage room (B246). Stephen contacted Chub for lab access. Done
  • Assemble Skyhook with the base and check the stability/safety/capacity/height/etc

- DOPO

  • Ask Paco to move the delicate instruments from the table. Done
  • Bring Skyhook to DOPO. The chamber seems already vented.
  • Find the way to place the cap on the floor safely and cleanly. => Stephen
     
  • Open the cap and then remove the crackle interferometer. Wrap it with something and place it somewhere in the room. How? => Stephen
     
  • Move the base to a dolly or something. Then put a cap on the base. => It'd be better to ask Caltech Transp for the chamber transportation.
  • Do we have to temporarily remove the laser safety curtain?

- OMC Lab

  • We probably need to separate the optical table and the base. Ask Caltech Transp to check how the work should be done.
  • Do we have to temporarily move anything on the way?
  • The table can be rolled out to the corridor and then rolled in to the CAML.

- CAML

  • Remove the grey rack and push the desk to the East.
  • Place the optical table.
  • Place the rack close to the table.

I've managed to cut and crimp wires for the power board for coil driver. I will begin adding components to the coil driver board.

- Add Components to Coil Driver board 

 - Replace some Sat Amp Componetns

- Still working on moving optical table to CAML

- Unsure if cryochamber has been cleaned and moved

  57   Sat Jul 2 09:22:39 2022 Juan GeneralGeneralProgress update

I've completed one coil driver board. 
Hopefully next week I can finish the other 2 boards and make the modifications to the sat amp baords.
