There was a discussion covering topics from re-use of existing waveguide to will the lighting be blocked, here is a summary:
- Should all new components be purchased? Decision was to reuse ~1/2 of existing waveguide parts and purchase all new flex sections since these are the only part prone to leaking. Discussion continued to say that the restoration will be more difficult to re-connect to new cryomodules in the "restoration" pahase on the project is complete. A purchase requisition (#373167) has been generated and submitted based on this discussion.
- The new installation of waveguide needs to be pressurized. This will be done by by drilling and tapping (1/8" NPT) the flange near the circulator in the gallery above each SSA. This interlock ties into the PSS and is under their control. They will decide how to route the gas lines and where to locate and secure the pressure switches.
- The longest piece is 20', and weighs ~60 pounds. This will require a two person lift. A detailed work plan must be developed
