This morning went to the FCES to look for the beams again. We turned the light into the FCGS fiber up to 4.7mW, then we were able to spot a bit of green light on the FC2 baffle and coming out onto SQZT8 (photos with Keita's camera will be attached tomorow). This beam was coming through the uncoated part of FC2, we were able to see this on the +X side of FC2 but not on the other side (probably clipped on the viewport). We put the beam somewhere on the coated face of FC2, and then we see much less green light on SQZT8. We moved FC1 + FC2 to see some kind of green flashes in the cavity, and also saw some IR flashes.
We returned to the control room, and switched the IR back to CLF from seed. We spent a good deal of time walking ZM2, ZM3, FC1, and FC2, and see some level of flashes in both IR and green, and a small transmission back through the VIP towards SQZT7. We can see that the co-alignment of green and IR isn't perfect.
Camilla is continuing this walking, but we will likely need some time tomorow to get all the beams going in the right places.
