Before this work, I performed the OMC alignment with PRFPMI
4:50 - 5:10 silent run
PEM injection using shaker on the beamduct between OMM and OMC
2025/04/22 05:10:00 - 06:20:00
Excitation : K1:PEM-EXCITATION_SR3_RACK_8_EXC
50 - 400 Hz , 1Hz resolution, 10 s in each measurement, 10 cnt
Fig.1. showed the results.
