Yesterday we put the viewport simulator on the -Y door of HAM1 to enable us to check the JAC REFL path, we had to move the in-vac mirrors for this path a couple weeks ago because the beam hit the side of a beam dump before hitting the second steering mirror after the JAC input coupler and so was mis-aligned.
The viewport simulator has tape marking the centre of the real viewport for this beam that was put in last time we had it up on this door.
We also rolled up the IOT1 table and plugged it in.
We had to move the table in -x direction from its ground markings as the periscope was too far right in the relative to the bellows hole and the viewport simulator, we also moved JACR-M1 as it was one row of holes too far in plus x direction.
The beam hit too high on the periscope, so it was missing the mirror by an inch, this will need to be corrected with pitch on the in-vac steering mirrors.
Pictures of the JACR-M1 move. First is the mirror position before the move, second is after the move, and third is a zoomed out view showing the input area of the JAC (temporary JM1 to be replaced with a tip-tilt suspension, JACR-M1, and JACR-M2).
