Injector positions (before, after, now) and A3 interception
Log Number: 4503987Logbook(s): Entry Makers: dchriBody:
A3 interception was a good PV to track the possible Injector charge --> discharge events
(Fig. 1,2)
I've split up the plot into 3 boxes
Red box = late Swing shift
Blue box = mid Owl shift - tuning, orbit adjust, separation checks, etc...
Green box = mid/late Owl shift - after being down and making changes
What confuses me is that without making any changes in the Injector, we somehow ended up with a huge reduction in suspected charge up and A3 interception (along with overall interception)
I'm happy the problem is gone. I'm not happy that there is no clear explanation
