The AC response of the SRM actuator has been calibrated.
(Summary of the calibration results)
BS = 2.190e-08 / f2 [m/counts]
ITMX = 4.913e-09 / f2 [m/counts]
ITMY = 4.832e-09 / f2 [m/counts]
PRM = 2.022e-08 / f2 [m/counts]
SRM = 2.477e-08 / f2 [m/counts] ( NEW ! )
(Measurement)
The same technique as I reported some times ago ( #4721) were used.
The Signal-Recycled ITMY was locked for measuring the actuator response.
Since the ITMY actuator had been already calibrated, first the sensor was calibrated into [counts/m] by exciting the ITMY actuator and then calibrated the SRM actuator with swept sine measurement.
- - notes to myself
SRCL GAIN = 2.2
Sensor = REFL11_I
Demod. phase = 40 deg
Resonant condition = Carrier resonant
Gain in WF = 0 dB
