1. Weekend Summary Squirted N2 at 3027 under various conditions
Trying to use as calibration for event pressure & timing profiles
Moved PR02-204x LER collimator
no significant change of trip threshold
Measured HOM power in absorbers
Q2BLW and IR4, IR 8
Heated up NEGs PR ,-8020, 3022
3022 shows interesting effect on her beam size
Took single-beam LER data up to 2450 mA
1st-time LER instability with large vacuum event in IR 2
BaBar threshold ≈15x normal
Ran with low abort rate at 1700 on 1070 mA
trip threshold seems to have gone up since 3027 plenum removal
