Quick Shot

Optics inspectors Scott Hylas (left) and Mark Bowman (right) examine the large UV-beam reflecting mirrors on OMEGA’s north-end mirror structure. Working 15 ft off the ground floor, Scott is also harnessed to the structure. There are a total of 120 large mirrors, with the second set residing on the target mirror structure (white containers seen in the Quick Shot from 08/01/11). The sixty focusing lenses and distributed phase plates found near the target chamber are more difficult to access and maintain.
