Advanced LIGO -- An International Partnership

Advanced LIGO will bring to fruition years of global research and development in key areas of LIGO technology. A number of U.S. and international institutions play lead roles in the delivery of AdLIGO subsystems. Caltech and MIT, the institutions that operate LIGO on behalf of the NSF and under the auspices of the LIGO Scientific Collaboration, continue to provide critical R&D, testing and integration in concert with the international partners.

  • Max Planck Institute (Germany): Pre-Stablized Laser (PSL) subsystem
  • Science and Technology Facilities Council (UK): Test Mass Suspension systems and some test masses
  • Australian Research Council: Thermal compensation wavefront sensors, interferometer controls components
  • University of Florida: Input Optics subsystem and additional components
  • Columbia University: Detector timing system
  • Stanford University: Cognizant Scientist for the implementation of seismic isolation
