[Pansophy] J1.3-09 Document Status for cavity tests

Thu Apr 23 13:20:20 EDT 2020

Anne (et al),

?The P-Team just had a discussion about Naeem's recent finding... NCRs in L2PRD are not matching the CAVSN's of the VTRF travelers.

What we have found, is that in some cases the NCRs were hand types rather auto-populated by the VTRF traveler and thus incorrect numbers are being used. Not only for the CAVSN's but also the SeqNum of the Travelers they should be referring to.

So,.... I was trying to show a list of possible problem, BUT I just lost remote desktop connection. I will finish my investigation and get you the rest of the information as soon as I can connect to JLab again.

This is just a heads up. If anyone finds a disconnect in CAVSNs between VTRF travelers and NCRs, please notify pansophy at jlab.org and we will try to work with the test engineers to resolve the differences.

Valerie / Pansophy Team

Hi Liang

Could you please take a look at the open cavity travelers and NCR for VTA on all L2 to add in any missing test informtion

Naeem has been asked to close as much documents as possible for L2 .For the remaining cavities that were not used likely the final disposition will be REJECT. Naeem will be able to go in and close the traveller/NCRs once there is a final disposition and data entered

Please let us know if you have any questions

Anne

Hi Naeem

Here is the list from J1.3-09 for documents remaining

However now that we hear from Joe that testing is still not done , there is likely more to come
