LIGO Document E1300757-v1
- The in-air and in-vacuum WFS share the demodulators, and in the current design also the RF patch panel. The proposed change would add separate patch panels to accommodate the in-vacuum WFS. Having the in-vacuum cables floating around and being forced to re-terminate them at the rear of the patch panel, whenever we change between in-air and in-vacuum WFS, isn’t reliable nor practical.
