We have done some work at ETMX today. We installed the baffle and placed two mirrors on the table.
The baffle position/orientation still needs to be checked more thoroughly to make sure that the beam will pass through the center of the baffle hole.
I must say that I am not at all happy with the baffle situation. It is currently completely blocking our camera view of the ETMX face. Here's a video capture of the ETMX face camera:
The circle is the baffle hole, through which we can see just the bottom edge of the test mass. I don't think whatever benefit the baffle gives out weights the benefit of being able to see the spot on the mirror.
This afternoon we will try to adjust the baffle, and maybe the camera view mirror, to see if we can get a better shot of the center of the TM. If we can see the beam spot through the hole we can probably live with it. If not, I think we should remove the baffle.
