[Pansophy] HE R&D Cavities - L2 cavities CAV040, CAV295, CAV331, being transferred to HE - next steps ?

[Mike Dickey]

Hi Anne,

For clarity, "L2" is ambiguous.  Pansophy has 4 projects that start with "L2", L2HE, L2PRD, L2PRO & L2Q0.  I understand that many folks refer to "L2" as the old project (L2PRD) and "HE" as the new project (L2HE).

To maintain traceability, I would suggest using the L2HE-INSP-CAV traveler, once it is written/ported from its L2PRD-CAV-INSP-CAV counterpart.  I would suggest not using STP travelers because it is not intuitive to search for project information there.

Also, serial number consistency is important.  The L2PRD serial numbers are CAV0040, CAV0295, & CAV0331, as seen in the L2PRD-CAV-INSP-CAV traveler.  Datamining will fail to match CAV040 with CAV0040 for example.

Let me know if you have any questions.

Hi All

We will be getting 3 cavities originally LCLS-II, that are being transferred to HE - Note from Katherine (18Feb2021)     We will be re- rinsing and retesting L2 cavities CAV040, CAV295, CAV331 as part of HE

In todays 1;30 planning meeting I learned that in the next week or two they will be wanting to do an abbreviated Inspection (Katherine /Ari will let us know, likely RF + surface finishes etc. )  , followed by the steps listed in Katherine's note  above

I asked about travelers - Naeem said we should not use L2  , Kirk Davis proposed an STP Traveler since it seems to be still in R&D phase  for HE . Katherine does not have her HE Travelers ready yet , although she may try to get these in place sooner now

So.......   I am assuming that we will use an STP Traveler and type in the SNs provided by Katherine - however please let us know if you think it should be done any differently

Thanks Anne
