[Pansophy] Fw: C100 spare helium vessel items & headers bellows QC

[E. Anne McEwen]

FYI- the C100 R Travelers as we know will likely need to get a refresh

So far Tiffany wants Ahsley to do a new HPR traveler , and now it looks like Gary has additional travelers to be updated

Hi Gary,

The travelers need to be converted and the names updated please. As for magnetic hygiene, do we have a program or requirement for C100s? Are we demagnetizing any other parts? Does t make sense to demag spares now or when they are certain to go onto a cavity? Is there a specification for the permeability that the vendor needed to meet?
Thanks,
Tony

Hi Tony,

Do you think I should convert C100 helium vessel and cryogenic circuit inspection travelers to C100R versions, or, use the old ones as is? The old travelers still have John Hogan as project manager.

The C100 helium vessel traveler has a step for magnetic permeability measurement, our original effort on magnetic hygiene control at the time. We can choose to i) keep this as is, ii) remove it, or iii) rewrite it to survey parts then demagnetize if necessary to align with LCLS-II magnetic hygiene control strategy.

Thanks,
Gary

Hi Tony,

We just received a few kits of C100 helium vessel kits and helium header bellows, which will be used as spares for future C100 refurb. They need to go through incoming inspection like did for other C100 HV items and headers parts. They were purchased using code C1010F. Which code is appropriate for the inspection work?

Thanks,
Gary
