Fig. 1: A, B, and C beam rels.
Fig. 2: Interceptions and currents. All injPID locks off.
Fig. 3: myaplots of Inj interceptions, currents.
Fig. 4: After zero pos. This zero pos is different from the Injector reference allsave zero pos.
Fig. 5/6: After turning on InjPID lock before 15 deg dipole (this is the area we are most sensitive to temperture fluctuations).
Fig. 7: Hall A off, just B and C on. InjPID locks on are 15deg dipole and A2 locks. Noting horizontal movement around 0I05H bpm. This bpm is just outside of Chopper 2.

Injector PID Locks working quietly in the background

17 hours 14 minutes ago
Log Number: 4284150Logbook(s): Entry Makers: dchriBody: 

After Injector PID Locks turned on [~2:41] and Once locks had some time to set in [~2:48]:

[Fig. 1,2]
0L09 seems to have quieted down
xB 2C24A BPM do not show much of a reaction

[Fig. 3]
xB Halo Counters do not show much of a reaction

[Fig. 4]
xC Ion Chambers do not show much of a reaction

[Fig. 5]
At first, xA Ion Chambers do not show much of a reaction. Once injector locks had time to set in, xA Ion Chamber (IIC1H00) Moller Target started getting noisy.

Injector PID locks ON ~2:40am

Log Number: 4284113Logbook(s): Entry Makers: dchriBody: 

To my understanding...

Efforts to improve stability in various areas (xC IonChambers, xB Halo Counters, xB positions) and further develope injector PID locks led to turning some Injector PID locks ON

[Fig. 1] 'Operator/Crew Chief' turned Injector PID locks ON
