LIGO Hanford Photo Galleries

Follow the progress of Advanced LIGO at the Hanford Observatory through the photo galleries below. Check the Advanced LIGO Web site for more details on this comprehensive upgrade of LIGO's trio of detectors. The Advanced LIGO program began in April 2008; the installation phase began on October 20, 2010 at the conclusion of the S6 science run. Check LIGO Hanford's Video Archive for clips of Advanced LIGO activities.

The Squeezer at LHO, Part II

June 24, 2011

Refer to the first squeezer gallery for a review of the quantum squeezing effort that's currently underway on the H1 interferometer. The LIGO squeezer team spent the first half of 2011 building up the squeezer optical table at LHO. In late June, the table was ready to move to its operating location adjacent to the H1 output beam line. In this gallery you'll see the table flying to its new home next to HAM 4 (horizontal access module -- a vacuum chamber). Once in place, the table will undergo re-assembly of the controls cabling. An optical path will be created between the table and H1's vacuum envelope. The work of integrating the squeezer with the full interferometer will continue through the summer of 2011, and the full experiment will unfold in the fall. You can trace the movement of the squeezer table from the staging area to HAM 4 using a map of Hanford's large instrument area.
