Now that ISC is done with their alignment, I have been working on testing the ISI. Last night TJ and I unlocked and balanced the ISI, I did some quick tests to make sure the actuators were pushing where I expected them and found the horizontal and vertical actuator for each corner was swapped, so I switched the cables at the chamber. This morning I did some tests like range of motion and CPS linearity and some quick spectra to check that all of the sensors looked more or less the same and a quick set of tfs to look for rubbing. Now starting my long overnight tfs, so hopefully there are no big eqs overnight. If those go well, I hope to have everything for the testing report by the afternoon tomorrow.

Attached images are some of the tests I did today. First image is CPS linearity, which looks kind of ratty because I think the purge was too high, but otherwise looks okay. Second image shows unlocked asds for the CPS, GS13s and L4Cs. No glaring issues, but the kind of noisy V2 GS13 and CPS made me think some rubbing or high purge was happening. Last image is a set of tfs I used for chamber closeout comparing the measurements on HAM8 from last year to HAM1 today. Looks okay for a quick measurement.
