This is an effort to get rid of our ground loops by isolating the electronic components from the optical table.
Aluminum mounting base plates of Thorlabs BA2 and Newport B-2 were replaced by plates or post made out of delrin material.
This is an insulator. DELRIN base plates were installed 6 places. The oplev-qpd has Nylon base plate.
The NPRO and HE/NE lasers are not isolated from the table. S8 and S9
I'm not sure about the doubling oven S10
The optical table is grounded at G11 through ~1 Mohms to the ETMY chamber.
Alignment touch up needed at all D-marked component!
