I've been chatting with Naeem. It seems that first of all,
CMASS-ASSY traveler's SN acronym for cold mass is changed to CMSN,
not the CMASSSN that I had in my original traveler. Panysophy team
must have changed that for some reason. <br>
<br>
CMSN implies cryomodule SN. Are we sure cold mass 01 will
definitely end up being used for CM-01? And cold mass 02 for
CM-02...as we know, LCLS-II's cavity string 6 was terminated. <br>
<br>
Jacob, maybe you can give us some guidance on this.<br>
<br>
Thanks,<br>
Gary<br>

D36 covers the tophat bellows cuff issue in general, so I
wouldn't expect it to list the tophat bellows SN. We should
expect to see this D3 repeated for the next 7 CM assemblies. May
we keep the current SN of PPU-01 and use the correct one for the
remaining 7 assemblies or can D3-36 be administratively
unresolved so I can change it?<br>

<b>Subject:</b> SNS PPU Cold Mass 01 D3's SN and SNType</font>
<div> </div>
</div>
<div><font face="Calibri">All,<br>
<br>
The recently released D3 33 and 36 for PPU cold mass 01 have
the same SN: PPU-01 and SNType: ID. These don't appear
correct to me.<br>
<br>
SRF spec/procedure PR-P-007 (attached) defines the format of
S/Ns. So, to me, the SN for cold mass 01 should be
104211500-A002-A-001.
<br>
As to the SNType, CMASSN should be used. <br>
<br>
The two specific D3 #33 & #36 address two issues
associated with two types of parts, the G-10 isolators and
FPC bellows, respectively. If a D3 is intended to address an
issue with one certain part, e.g. only one of the four FPC
bellows, then I think the D3 should use the SN for that
specific bellows and SNType should be what we created for
the FPC bellows.
