Follow-up Re: Downtime Incident CREATED: Inj energy dropped after xC went to BNR, sending to xB
Log Number: 4515496Logbook(s): Body:
While this initially appeared to be an energy shift, it ultimately looks like it was a combination of a little phase slipping in the injector coupled with the injector orbit lock attempting to lock only Hall B beam while C was down and the locks were inadvertently left unhalted. This tuning downtime turned into a blocked downtime before we fully understood what was happening; in hindsight it almost certain that the issue was caused mostly by the errant locks, though it wasn't clear in the moment.
