In run 158 at around 01:00am PCP took the beam to try to optimize it. We got the beam back after ~15 minutes.
Beam intensity ~1.2e7

We had the beam back at 4.00 a.m.
Beam profile and intensity checked: 1.2e7

This is what we were seeing in agata. We think it might be possible we were having a bit of beam implanted somewhere. We called PCP to check.

|
Fixed, e768s, Tue Jul 30 04:40:18 2019, Jenn & Franco & Teodora, RUN, General, LiF, Beam back at 4.00 h
|
Due to the high rate of AGATA and Mugast (probably due to some implantation) we asked the PCP to readjust the beam.
They centered it a bit more on the profiler and now it looks better. Attached are the new rates.
