[Pansophy] SNSPPU-INV-CMMC

[Gary Cheng]

Mike,

Per our discussion, I agree with your suggestion to have four separate 
acronyms and INV travelers. I will prepare 4 INSP travelers accordingly.

The Helium Inlet Baffle Assy is part of the kit "SNS PPU Cryomodule Cold 
Mass Assembly Machined Parts". We may use CMMC for this kit. The other 
three acryonyms look good to me.

I also agree that we shall have 4 different dropdowns in the ASSY 
travelers. Matt and myself are responsible for the Cold Mass Assy (me) 
and Final Assembly (Matt) travelers, we will pay attention to this.

I think in the assembly travelers, it would be helpful to keep a record 
(comment box or file upload in pansophy terms) of the SNs of the kit 
members actually installed. This is because that per LCLS-II experience, 
the assembly folks prefer to have the liberty to use components from a 
"sick" cryomodule elsewhere. When that happens, an elaborate kit is 
disbanded but we can still trace which kit member goes onto which 
cryomodule in the end. Comments are welcome from you all.

Thanks,
Gary
