Mechanical Isolation Design of Vopo LIGO MIT Lab

Slide Note

The project details the mechanical isolation design for the Vopo LIGO at MIT Lab, covering aspects such as suspension analysis, optical table optimization, and conclusions. It focuses on the seismic isolation of aLIGO, featuring vacuum chambers and CAD models of the suspensions. The concept includes the suspension of springs, cables, stages, and optical tables at aLIGO, showcasing initial concepts and improvements for Vopo's suspension design.
