Summer in the Hex River Valley - grapes Everywhere! A truly beautiful scene in this magical place...
Meanwhile, in the clean room we're getting everything ready for the M2 null test. Here's the fold mirror going into its cell.
The SAC's tilted to the operational angle of 37 degrees for the test & needs to be securely locked down in this position.
Before trying to align anything, we made sure all the hardware fits & works - first the fold mirror at the bottom of the test frame...
Then the null lens in its cell, attached to its kinematic mount.
So far so good - tomorrow we'll set up the interferometer on the frame & have a go at firing a laser through the system!
