The ISCT6 enclosure is now in place by HAM6 with two light pipes installed. ASAIR and OMC_R are successfully extracted to the table.
We craned the ISCT6 table from the squeezer bay over to the north side of HAM6. We carefully adjusted the position of the table by rolling it. The table legs were then secured on the floor. With help from Gerardo and Filiberto (a big thank you for Gerardo and Filiberto who machined the holes for us even though the working hour was over !), we made a 10 inch beam penetration hole on two back panels of the enclosure . These are for the ASAIR and OMC_R beams respectively. Note that we could not see a bright enough OMC_T beam this time and therefore we did not try to make a hole on the last back panel. This will be don once we reliably confirm the OMC_T beam position. We put the flanges and light pipes for the two beams and now the beams are successfully coming out to the table.
Also, in the process of trying to find the OMC_T beam, we turned on the PZT high voltage. We need to make sure that the high voltage is off when we pump down the chamber tomorrow.
We made a rough alignment of the table and connected ASAIR_A and ASAIR_B to the electronics rack. The alignment will change once the pumpdown starts tomorrow, but for now we have checked that the RFPDs are alive.
We're ready to make a beam scan measurement of the AS and OMC_R beams on the table to characterize the mode matching, we'll do this tomorrow. (Tonight Kiwamu was adjusting the alignment of the PRC, I thought it best to let him finish.)
The high voltage to the PZT has been turned off.
