3 10ms acquisitions from the kick up to the top of the ramp. Gap of 4 minutes between acquisitions with a least 4 SC changes….

SPARE LHCINDIV + CNGS instead of TOF SPARE AD-EASTB

Next steps : - Correlation between acquisitions during tune ramp and supercycle fluctuations. - Comparison with measurements during dedicated MTE supercycle. - Measurements with various PFW’s configurations.
