X arm IR transmission

Aaron, Luis, Fil, Sheila

There is now a camera installed on the IR trans path at the x end.  The image is of the IR path incident on a baffle (a scratched up, old piece of aluminum painted black, to be more acurate.)  There is about 30uW of green power coming out of the chamber into the IR path, you can see a square of 4 green ghost beams on the camera image, and ocassional flashes of the IR beam.  Adding a dichroic to the path might make it a little more clear what is going on here.  

We sent the signal to the red cable behind the monitors in the front row of the control room.  I unplugged the image of the BS from the top monitor, and replaced it with this camera.  IF anyone want to see the BS camera, plug the blue cable back in.
