Future Gravitational-wave Facilities: Zoom 13

SEED Magazine ~2010

2 of 9

Welcome

  • This session: description of future GW observatories/facilities, open questions, opportunity for collaboration
  • Types of GW Detectors:
    • Laser Interferometers (ala LIGO, Virgo)
      • Space, Moon, Earth
    • Atom based Interferometers
    • Resonant Acoustic (bars, etc. -- mostly no longer operational)
  • Some areas with lots of overlap:
    • Newtonian Gravity noise
    • Laser beam stabilization
    • Quantum metrology: squeezed states, etc.
    • Large vacuum systems
    • Low noise cryogenics
  • Timeline: which GW facilities will be on-line in which Epoch ?
