Subject: [EXTERNAL] [Sphenix-maps-l] second half barrel tested

Cameron, Zhaozong and I completed the “fast” stave test on all staves of the second half barrel this morning. All staves tested “gold”. So the transport did not seem to have damaged anything. There was one stave which had the analog power firefly connector slightly detached, but after pushing it back in, that stave responded properly as well.

During our cooling loop tests yesterday we discovered one stave where the PT100 measured around 154 Ohms (instead of around 112 Ohms as compared to the other staves). We are not sure what the problem is with that one.

The surveyors will 3d-scan the barrel later today at 1p
