[Pansophy] SNS PPU inspection traveler breakdown structure

[Katherine Wilson]

The idea is to break the travelers down by workstation, so one person is responsible for the part as long as it is being inspected under that traveler.

We are trying to minimize travelers that stay open for months while working through the inspection process, and also reduce misplaced or damaged parts as they are passed from one workstation to another, so please let that be your guide as you decide how to separate the travelers.

I think you will just have to use some judgment about what seems like a sensible way to separate travelers.  Maybe Anne has further suggestions.

Regards,
Katherine

Ed & Naeem,

It's unclear to me if there is a consensus on how many breakdown travelers that PPU project wants to have for a certain assembly to be inspected. I hope that you can clarify what you want all SOTRs to prepare.

The usual receiving inspection steps that I can think of are:
shipping crate condition check --- this would be in INV
vendor documents check --- docs upload to INV. SOTR as well as SMEs need to check them for completeness and correctness
visual inspection --- SRF QC or CMA
dimensional inspection --- may be done by SRF QC folks or Survey & Alignment folks
instrumentation electrical check out --- Larry's group
fit-up test  --- mostly done CMA
weld inspection --- by weld examiner or CWI
cold shock  --- CMA
pressure test  --- CMA
leak check  --- CMA
repackage

Please advise. I am about to convert Ed's SNS end can travelers to the new format and need to know how many travelers that I need to write for Supply & Return End Cans.

Thanks,
Gary
