Subject: acoustic enclosure for input beam 

The enclosure box for input optics are done. We still need to order more of the nuts for one panel, but the box should provide certain acoustic shielding for now.

We will measure the beat signal once the temperature stable.

    The box has four 1-inch diameter holes, 2 for periscope, one for input beam, another one is for the beam to RCAV curve mirror which we cannot fit in the box.

    We had to rearrange the cable for ACAV AOM to have fewer cables going in and out the box. The cable for driving the AOM was remade so that it did not block the panel.
