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>

<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.

Comments are welcome.<br>
