  5. “Antenna pattern” “peanut”

  6. LIGO high frequency sensitivity “FSR” (free spectral range) 37.5 kHz Class. Quantum Grav. 25 (2008) 184017

  7. Antenna pattern at FSR

  8. Directional sensitivity

  9. LIGO calibration Nucl. Instrum. Meth. A624 (2010) 223arXiv:1007.3973

  10. Enhanced LIGO detectors

  11. Squeezed Detectors

  12. Advanced LIGO/ Advanced Virgo ~10 times better, lower frequencies in band Installation in progress

  13. Initial vs Advanced LIGO Simple pendulums become monolithic, quadruple pendulumswith better quality optics Prototypes being tested, optics are polished

  14. Initial vs Advanced LIGO Lasers become more powerful: 10W  200 W Installed and being tested at LIGO Livingston.

  15. Initial vs Advanced LIGO Seismic isolation goes from passive to active HAM SEI tested in S6 Most chambers have now their “SEI” installed.
