(For Evan and Nic)
Our current alignment procedures:
1. Lock green to both arms. Make sure all the sus guardians are in the proper configuration, ie. SUS_ETMs, SUS_ITMs, and SUS_TMSs are all aligned. H1:ALS-X_TR_A_LF_OUTPUT should be a little above 1 cnts, H1:ALS-Y_TR_A_LF_OUTPUT will be a little below 1 cnt. Align ITMs and ETMs as needed (if hopless, check TMS alignment on ITM baffle PD1 and PD4). Make sure both ALS_XARM and ALS_YARM guardians are set to LOCK_NO_SLOW.
2. After you are satisfied with the green alignment, make sure LSC_CONFIGs guardian is managed, and run ISC_DOF guardian to INPUT_ALIGN. This should lock the IR to the x-arm and misalign the y-arm cavity. You should see LSC-X_TR_A_LF_OUT go to around 1cnts. This will start the asc wfs and adjust IM4, PR2 to improve IR input alignment. Verify that LSC_ASAIR_A_LF_OUTPUT goes about 4,000 cnts. Then on ISC_DOF run SAVE_INPUT_ALIGN, this will offload the asc wfs to the alignment sliders. You MUST save the alignment values (ASC --> IFO_ALIGN.adl).
3. Then, on ISC_DOF run PRM_ALIGN. This will first lock PRX and engage the asc wfs for PRM to maximize the power buildup in LSC_ASAIR_A_LF_OUTPUT. Once you are satisfied with the power buildup, run ISC_DOR OFFLOAD_PRM so that the wfs are offloaded to the alignment sliders, again you must save the new alignment.
4. Set ISC_DOF to DOWN, and LSC_CONFIGS to MICH_DARK_LOCKED. Using the AS_AIR camera align the BS manually and save your new alignment values.
5. Return to ISC_DOF and run SRM_ALIGN. This will first lock SRY and engage the asc wfs for SRM to maximize the power buildup in LSC_ASAIR_A_LF_OUTPUT. Once you are satisfied with the power buildup, run ISC_DOR OFFLOAD_SRM so that the wfs are offloaded to the alignment sliders, again you must save the new alignment. (This step only required for DRMI locking).
FOR PRMI SIDEBAND LOCK: Set ISC_DOF to DOWN, set LSC_CONFIGS to PRMI_SB_OFFLOADED
FOR DRMI: Use ISC_DRMI and go to desired state. You will need to align various optics on your own because this guaridan does not manage any of the sus states.
------------------------------------------
ALS_COMM guardian runs on its own, and can be set to IR_FOUND.
ALS_DIFF can be set to the LOCKED state. You will need to enter the LSC input matrix (H1:LSC-PD_DOF_MTRX_SETTING_1_28) on your own. At the moment the script leaves this as zero since our gains have been changing. The LSC_DARM boosts are also currently commented out.
