I am drafting PPU mag shield receiving inspection travelers. We
have a complex situation regarding the mag shields:<br>
1. There is a set of spare inner mag shields made to SNS HB CM
drawings and repaired by Amuneal.<br>
2. There is a set of spare outer mag shields made to a combination
of SNS HB CM drawings and SNS PPU drawings<br>
3. We will receive 6 sets of inner mag shields made to SNS PPU
drawings<br>
4. We will </font><font face="Calibri">receive 6 sets of outer
mag shields made to SNS PPU drawings<br>
5. </font><font face="Calibri">We will receive 7 sets of outer
mag shield supply extensions made to SNS PPU drawings<br>
6. </font><font face="Calibri">We will receive 7 sets of outer
mag shield return extensions made to SNS PPU drawings<br>
7. There will be extra mag shield parts, some are large, that will
not be used for SNS PPU cryomodules. Most of these were sent from
ORNL.<br>
<br>
On serialization,<br>
1. I am not sure how the spare inner and outer mag shields are
serialized. Likely the parts/subassemblies are serialized and
engraved. The fact that the spares are now made to a mix of SNS
HB and SNS PPU drawings will make precisely following SRF's new
serialization policy difficult, unless we create new top assembly
drawings for the spare inner & outer mag shields. <b>--- any
suggestion on serialization of the spare shields, at
assembly/kit level? Shall we give them S/N 007 and use SNS HB's
inner & outer shield assy drawing numbers and make notes in
travelers to state that they are SNS spares? </b><br>
2. All new SNS PPU inner & outer magnetic shields are
serialized from 001 to 006.<br>
3. All new outer mag shield extensions are serialized from 001 to
007.<br>
<br>
On acronyms and travelers,<br>
1. Currently we assigned acronyms IMAG and OMAG for the inner and
outer mag shields, respectively. <br>
2. INV travelers for IMAG and OMAG exist. <b>--- We need to think
about how to use them to inventory the first 6 types of shields
mentioned above. </b><br>
3. To avoid adding more acronyms for mag shields, I will use IMAG
to create the inner magnetic shields inspection traveler, which
will be used in inspection of both the spare and new inner
magnetic shields. And I will use OMAG in the outer magnetic shield
inspection traveler, which will include receiving inspections of
the outer mag shields, supply extensions and return extensions.<br>
4. I will give instructions on how to match the outer magnetic
shields with supply and return extensions in OMAG INSP traveler.
The match-ups will be only for receiving inspection purpose.
Inventory may issue any combinations of outer + supply extension +
return extension to production.<br>
<br>
Sorry for the long message. Comments & suggestions are
welcome.<br>
<br>
Thanks,<br>
