AS path alignment |
|

[Yuta, Tega]
We finally managed to steer the AS beam from ITMY chamber, through BS and IMC chambers, to the in-air AP table.
We moved the AS5 mirror north to its nominal position and we also moved the ASL lens on BS chamber back to its nominal position. Attached photos are taken after today's alignment work. |
