LIGO HEPI Actuators
KineOptics assisted with the final design, managed the manufacturing, and did the assembly and testing of 108 of these actuators. They are welded units and were leak checked with a Varian Helium leak detector. This is a stereo image of some of them in the LIGO Livingston clean room staging area awaiting installation.
