Abstract

Describes an ultra-low-noise, low-frequency, six degrees of freedom active vibration isolator to demonstrate that a high degree of reduction can be achieved for vibrations at the support points of a gravity wave detector's final pendulum system. Design and dimension of the isolator; Achievement of active isolation by six servocontrol loops; System noise limitations.

12. Possible high-mobility LAGEOS ranging station

Author

Bender, P.L., Faller, J.E., Levine, J., Moody, S., Pearlman, M.R., and Silverberg, B.C.

Abstract

A relatively low-cost system for determining both the vertical and horizontal coordinates of several dozen points per year with an accuracy of about 2 cm appears feasible. One approach considered is to use a subnanosecond pulse length laser with a few millijoules per pulse output energy and to employ single photoelectron detection of the returned signal. The single photoelectron approach has been thoroughly tested in the Lunar Laser Ranging Experiment. With a laser average power of about 50 mW, a 30-cm diameter transmit-receive aperture, 10 arc sec pointing accuracy and a beam divergence of 20 arc sec, the expected returned signal level is about 70 pulses in a 3-min interval. If the differences between the observed ranges and those calculated from a reasonably good LAGEOS ephemeris over a 3-min interval are considered, the expected standard deviation of the mean is < 0.7 cm.
