[Pansophy] FW: L2HE CAVSN renumbering

Wed Jan 3 12:05:20 EST 2024

Here is the discussion Ashley, Tiffany, and I have been having on the L2HE CAVSN renumbering request.

This has not been done for any other project.
The use of NCRs and the RTV.

The use of a "marker" to put the new SN (the CAVSN was not changed by RI) will not work.

Just some FYI

Yes, I believe the current situation is that inspection (CMM and RF/Tuning) are doing incoming inspections of the refurbished cavities.  So there should be a record, I think, in Pansophy for each of these cavities with incoming inspections, initial VTRFs, maybe some chemistry / assembly rework and re-test, and then an NCR with RTV.  (This is my assumption based on how things should work but I haven't checked the cavities to verify this.)  So now there would be new incoming inspections.  I agree that we have precedence for not changing the SN (especially since the SN etched wasn't changed) and that anyone doing proper research into the history should be able to follow the records (if they are filled out completely and correctly) in Pansophy.

I don't think we have any "rules" on this situation though.  Should instructions on this situation be under the Inventory ISO process?

The NCR should have captured the RTV decision, did/will the cavity get another incoming inspection or logged into inventory? I would think that creates a line in the data to capture before/after retanking.

C100 also didn't change the SN after removing and replacing the HV, there is a precedence for keep it as-is.

Since RI didn't change the SN etching, maybe we should push back that they should continue using the original SNs?  Is there some way to have an NCR that rejected the cavity (return to vendor) and then allow that SN back into production?

Oh, thanks for correcting me, I thought we renamed then when they came back as C75s.

I'm sorry - MARKER?!?! No, that doesn't work, it should be engraved at least with whatever is decided.

Actually, RI didn't change the SNs. John V/Adam G are requesting the change and plan to write with Marker. Not sure that works.

For the C100's, we don't rename the cavities.  The project is C100R but the cavity SNs are still C100-RI-###.  If I use the Datamine function, I just use the dates (or the Project ID) to tell whether it is original or refurbishment.  For C100-RI-074, it has been un-tanked but not yet re-tanked, and it keeps the same SN.  I think the difference between the C100/C100R case and the L2HE case is that I believe RI actually edited the etched SN on the L2HE cavities.

Hi,

Not sure if I'm too late.

I like Tiffany's idea of changing the original name, it would move the old number away from the new number in the drop down list and less likely to be accidentally selected. Is that possible? Would that impact the data somehow?

I'm trying to think of when this has happened before - C100s get the R added, when C20s and C50s are made into to C75s, there was a traveler to capture the end groups on the original cavity I think? I think C100R-74 was retanked, but I think we left the number the same?  That's the only similar example I can think of.

- Ashley

I think the primary answer is that Pansophy keeps the record of what happened so using the Datamine gives the list of recorded actions to the cavity.  But all Project Coordinators also keep personal "notes" (spreadsheets) of what happened, and these are typically added to the WCP excel file.

How do you currently keep track of what happened to a cavity?

Do you renumber?

Can the system allow you to rename a SN?  For example, the previous HE-R123 becomes OBS_HE-R123 and a new HE-R123_RT is added to the drop down.

Subject: L2HE CAVSN renumbering
Importance: High

Tiffany / Ashley,

Adam G / John V are requesting us to renumber 9 cavities in L2HE. These were sent back to vendor to be re-tanked/re-processed.

Ex: HE-R094  -> HE-R094-RT

The request is to Obsolete old number so that they can't be selected in drop downs in travelers.

This can't currently be done in the present system.

Accepting new numbers is not a problem, but obsoleting is a problem.

Question: How do you handle cavity rework? How do you annotate? Do you renumber?

There is a NCR in the system stating that it was RTV. The claim is that it will confuse production by keeping the numbering the same and cause problems trying to remember what data to "ignore".

Please respond ASAP as they are pressuring me for an answer.

Thanks

Valerie Bookwalter
