Today Sheila and Matt have been doing some IFO/CO2/OMC scan tests, in doing this we noticed the CO2X looked very misaligned, plots of CO2. However the SLED has degraded v. quickly since it was last swapped May: 84417, and even the IFO beam plots (120s and 7minutes) look a little strange and clipped.
We plan to replace this SLED before we decide if the CO2X is really misaligned or not. Procedure to realign CO2s with picos is: 68391, most recently blasted 2W for 2mins and waited ~10mins between pico moves. Last checked Oct 2024 80834 for ITMY and March 2024 for ITMX 75987
After TJ and I replaced the ITMX SLED 87353, the ITMX CO2 alignment looks a lot better now, I don't think it needs to be adjusted.
I blasted 2W of CO2 for 2 minutes on ITMX and ITMY in turn, attached is HWS images, red cross is IFO beam position we want OC2 centered around.
