Di. Robertson et al., THE GLASGOW 10-M PROTOTYPE LASER INTERFEROMETRIC GRAVITATIONAL-WAVE DETECTOR, Review of scientific instruments, 66(9), 1995, pp. 4447-4452
We present a description of the prototype interferometric gravitationa
l wave detector at Glasgow. The detector, which has been under develop
ment for a number of years, consists of two perpendicular 10-m-long hi
gh finesse Fabry-Perot cavities formed between test masses hung as pen
dulums and is illuminated with a cw argon ion laser. The differential
displacement sensitivity of the detector is similar to 7x10(-19) m/roo
t Hz from 500 Hz --> 3 kHz and is close to being limited by photoelect
ron shot noise in the detected photocurrent. (C) 1995 American Institu
