Iris Mounts on Cavity Windows, posted by Manar Amer at ThomX igloo about utilities

In order to find the Alignment of the ThomX cavity, Yann built mounts that could be placed directly on the windows outside the cavity, where we can place
an iris at the center.
The center of the iris on the mount corresponds to the center of the mirror. |

New valve cabling and 30Hz noise PZT, posted by Loïc Amoudry at Optical room about lasers and optics | vacuum

The Pneumatic valves are still coming back to "close" position.
Now the air bottle is always "open" to keep the valves "open".
The 30Hz noise is still here. We tried to cut off all the air flows. It only decreased the noise intensity but didn't change its shape. |
