SUMMARY:Gravitational-Wave Detectors above 10Hz: Weber Bars\, LIGO\, GEO\,
  VIRGO\, TAMA\, LCGT\, and Einstein Telescope - Kip S Thorne\, The Feyman

DESCRIPTION:Thorne will describe sources of gravitational waves above abou
 t 10Hz (neutron stars\, black holes\, cosmic strings\, ...) and the two ty
 pes of detectors that are being used to search for those waves: Weber bars
 \, and optical interferometers. The first generation interferometers (init
 ial LIGO \, initial Virgo\, GEO600\, TAMA300) are nearing completion of th
 eir data collection and are producing astrophysically interesting results\
 , but no detections as yet. The second generation (advanced LIGO\, advance
 d VIRGO\, GEO-HF and LCGT ) have begun construction or will do so soon\, a
 nd have a high probability of detecting a wide variety of sources. R&D for
  the third generation (LIGO-III\, Einstein Telescope) is now underway. By 
 changing the experimental protocol but not the apparatus\, the second and 
 third generation interferometers may also be used to study quantum behavio
 r of human-sized objects—- e.g. quantum entanglement of 40 kg masses sev
 eral kilometers apart\, and “Schrodinger-cat” quantum states.
