H1 ISI CPS Sensor Noise Spectra Check - Weekly FAMIS 27396
Closes FAMIS 27396. Last checked in alog 87787
Plots look fine compared to last week but BSC High-Freq noise is elevated for these sensors:
ITMX_ST1_CPSINF_H1
ITMX_ST1_CPSINF_V1
ITMX_ST2_CPSINF_V1
Note - it is Tues Maint. so there are people in the LVEA.
There was a 7.5Hz peak in TJ's last-week check that is now gone. It was most prominent in HAM1 it seems.
