Second generation HAM seismic isolation platform for LIGO 2 stages, 12 DOF
After HPD built a successful proof-of-concept vibration isolation device for LIGO scientists in just two months
in 1999, our engineers were engaged to create a second-generation platform in 2002. This two-stage, 12 degree
of freedom seismic isolation system was designed for installation in a LIGO horizontal access module (HAM) high
vacuum chamber at Stanford University's Ginzton Lab. This system uses passive and active vibration isolation
technology to provide a stable platform for the gravitational wave detector optics. The HPD engineering and manufacturing
team collaborated closely with LIGO physicists and technicians on the design and analysis of the proposed system.
HPD then fabricated all the parts, procured all the components, assembled and tested the platform. The integrated
team was able to accomplish this extremely rapid development in less than one year!
