Comment: 271uA linac current
Beam Conditions:
Total Linac Current (R2XXITOT) = 271.98
Hall A Current (IBC1H04CRCUR2) = 5.01
Hall B Current (IPM2C24A.IENG) = 2.51461
Hall C Current (IBC3H00CRCUR4) = 64.8
Hall D Current (IBCAD00CRCUR6) = 1.5
BSY Current (IBC4C00CRCUR5) = 0
INJ Energy (MMSINJEGAIN) = 110.587
NL Energy (MMSLIN1EGAIN) = 980
SL Energy (MMSLIN2EGAIN) = 980
Gradient Problems:
1L06-1 Gradient Loop Detector Error RMS (GLDER)=83 (<=0 or >=80ppm)
1L06-3 Measured Gradient (GMES)=0.123 (>=0.1) with RF OFF - Check Detuning or reset faults
1L06-3 GLDER=970 (>=200) with RF OFF - Check Detuni

Injector Re-Steer
Log Number: 3975330Logbook(s): Entry Makers: moserBody:
Figure 4: C-beam relative to when Injector was last optimized 1/19.
Figure 5 and 6: Re-steered through 0L01. No terribly big changes, but did find it odd how much I had to crank of MAD0I06AH/V to get 0I07.
Figure 7 and 8: 0L->0R re-steer, InjOrb and energy locks on.
Checking CW to ILD now. Figure 9: 65uA CW from C-laser to ILD.
Figure 10: Well, A1/A2 interceptions much lower now, and 0R01 as well, although need to add 5uA from A-laser.
Figure 11: +5uA from A-laser. Looks like we made improvements.
Back to the Halls.
