Right click on [[http://172.16.32.60/kagra_mannual/img/CRY_CUST_TYPEA_MN_OLSET.png|slide bar]] and select “-1” as an increment. Never select large increment. * Adjust (IE)TMX alignment to lead their spots on both (IE)TMX to be around center. Ideally, K1:AOS-TMSX_GR_PDA1_OUTPUT should be maximized. *Or, Maximize K1:AOS-TMSX_GR_PDA1_OUTPUT by adjusting, firstly Yaw of IETMX and secondly Pitch. 1. Remember the value of [[http://172.16.32.60/kagra_mannual/img/AOS-TMSX_GR_PDA1_OUTPUT.png|K1:AOS-TMSX_GR_PDA1_OUTPUT]] (assuming VtmsxGR-0). * Anyway, move Yaw/ETMX in one direction until you observe slight reduction of VtmsxGR-0. * Move Yaw/ITMX in both direction to find max of VtmsxGR. * (4-1) If you can find better VtmsxGR than Vtmsxgr-0, it means your selection for ETMX actuation is good direction. (4-2) If worse, bad direction. * If good, repeat (2) (3) until you encounter (4-2). If bad, select opposite actuation then repeat (2)(3) until you encounter (4-2) again. * If you find max point, perform (1)~(5) for Pitch/(IE)TMX. (1)~(6) is regarded as one “set” optimization.Ideally, it is better to perform 2 sets for each Yaw/Pitch. * ''' X arm FP axis is established and PR3 P/Y is fixed.''' * '''X arm GR alignment (Record good TMSX).''' * '''X arm IR alignment (Resonate IR).''' * '''X arm IR alignment (PR2-IMMT2 alignment).''' * '''X arm IR alignment (GR/IR resonance check).''' * '''X arm GR/IR alignment Established.''' * '''Y arm IR alignment Preparation.''' * '''Y arm IR alignment (Resonate IR).''' * '''Y arm IR alignment (Check spot position on ETMY).''' * '''Y arm IR align (Adjust BS for ETMY spot centering).''' * '''Y arm IR alignment (ITMY,ETMY alignment).''' * '''Y arm IR alignment (Check spot on ITMY).''' * '''Y arm IR alignment Established.''' * '''Y arm IR alignment (Record good TMSY).''' * '''Y arm IR alignment Established.''' * '''Y arm GR alignment (Resonate GR).''' * '''Y arm GR alignment (TMSY GR maximize with SR3).''' * '''Y arm GR/IR alignment Established.''' * '''FPMI Recovery (Exit from alignment mode).''' * '''FPMI Recovery (Align ITMX).''' * '''FPMI Recovery (Start FPMI).''' |
