REFL and AS paths aligned at AP table |
|
|
After Xarm and Yarm were aligned by Anchal et al, I aligned AS and REFL path in the AP table.
REFL path was alreasy almost perfectly aligned.
REFL path
-REFL beam centered on the REFL camera
-Aligned so that REFL55 and REFL33 RFPDs give maximum analog DC outputs when ITMY was misaligned to avoid MICH fringe
-Aligned so that REFL11 give maximum C1:LSC-REFL11_I_ERR (analog DC output on REFL11 RFPD seemed to be not working)
AS path
-AS beam centered on the AS camera. AS beam seems to be clipped at right side when you see at the viewport from -Y side.
-Aligned so that AS55 give maximum C1:LSC-ASDC_OUT16 (analog DC output on AS55 RFPD seemed to be not working)
-Aligned so that AS110 give maximum analog DC output |
