[Pansophy] L2HE Cavity String / cryomodule SN

[Mike Dickey]

All,

In the past CSTSN=22 would always progress to CMSN=22 where the serial number was always maintained, but the acronym would change based on what is was at the time.  The cleanroom folks build cavity strings and the folks on the floor build cryomodules.

I’m fine with CMSN at all workstations, but some folks may not agree.

I also would prefer to use the same SN for CST and CM.  I’ll go ahead and put <<CMSN>> in the CST assembly traveler.

Although it seems a little weird, I think the easiest thing as we get into production will be to use the same numbers for everything, i.e., start at 22. But other thoughts are welcome if you disagree.

We can do either! I think CSTSN and CMSN tend to be matching numbers so if you prefer to just use CMSN, it won’t cause an issue.

I’m not sure if this is a Katherine question or a Pansophy question (or someone else) –

For the L2HE cavity string assembly traveler, I need to know whether we will be using a CSTSN (cavity string SN) or a CMSN (cryomodule SN).  I believe for some projects, there is a CST SN for the Cleanroom CST assembly, and then a different number for the CM SN for the Cryomodule assembly.  I’m not sure what the plan is for L2HE.
