Getting a baseline for how much the HAM chambers have moved since they were locked.
- HAM4
- HEPI RX,RY,RZ changed by 5urad, 6urad, 0.2urad
- ISI RX,RY,RZ changed by 5urad, 1urad, 26urad
- HAM5
- HEPI RX,RY,RZ changed by 4urad, 0.3urad, 0.7urad
- ISI RX,RY,RZ changed by 7urad, 3urad, 45urad
- HAM6
- HEPI RX,RY,RZ changed by 18urad, 2urad, 6urad
- ISI RX,RY,RZ changed by 6urad, 3urad, 30urad
Highlighted the highest changes but none of these look particularly large.
HAM5 and HAM6 tripped just at the end of these trends too, not included in differences above, maybe a WD trip when a SEI is locked doesn't matter anyway.
Same comparisons are below for HAM1, HAM2, HAM3 for before and after HEPI Locking
HAM1:
L4Cs: Just got noiser since Jim moved them. I don't think this can be used as a comparison for alignment but screenshotted below nonetheless.
HEPI: Largest change is in Z with 11.2um
HAM1 plots also show another change about 4/5 hours ago, which is the HAM1 vent
HAM2:
ISI: Largest change is in RZ with 22.3urad
HEPI: Largest change is in HP by 10.9um
HAM3:
ISI: Largest change is in RZ with 23.4urad
HEPI: Largest changes are Y by 10.3um and VP by 13.8um
