Summary Report
Type-A
- Replaced the coil drivers for ACC from HPC to LPC for Cryo-payload in IX/IY.
Type-B
In the context of F0 LVDT sensor correction,
- The idea of using the force TF to compensate the lack of data in the displacement TF was successfully tested for SR3.
- Inter-calibration factors with the ground seismometer were calculated for SR2 and BS.
Type-Bp
In the context of SF LVDT sensor correction,
- Inter-calibration factors for PRM, PR3 and PR2 were calculated, but
- Only the one for SR3 seems reliable, because in the others, the 2nd peak appears at different frequencies in the displacement and force TFs. This means the force TF cannot be used for the calculation.
