REFL165 was installed on the AP table last night.
Meanwhile I found the DC power level at the REFL PDs were 0.8~1.2V if the PRM is aligned and the IFO is not locked.
This corresponds to 16~24mA (20~30mW). This is too big.
The HWP of the REFL path were adjusted so that we have 6~10mA (8~12mW) on each PDs. |
