Work on software mostly. CC efficiency work ongoing (also possible
from command line from eep ntuple of course)
only at 22.40 we went to D-tunnel to restart the daq. Coda now works and
we are taking cosmics, starting adn stopping runs. However we had a camac
problem at startup. This may be not the first time that the camac screen
does something we do not understand.
we could first pass all downloads and verify. No data even from CFDs. Then
I checked "read crate" from a CFD module => garbage. Download and verify
from each cfd, download and verify all (a few times). no data.
Then I played some more with the inp register on camac 2, slot 22. Only
after I "cnaf blrocv1 2 22 0 16 16777215" I get data. If I write 0 on that
address I get no data (!). Addres 1, is instead irrelevant (!)
Another camac symptom (this was 3/4 days ago) was having to hit download
twice before the physics trigger came back.
Well, we don't want to shut down camac just yet. I will throw in another
display on camac 1 tomorrow to further debug things.
This problem may actually have to do with the code, the controller or the
BHWY cable. Tonight's shift should be all set to go with the flasher and
cosmic runs. The SH is being locked and we may have an injection tonight.
Beam has priority.
