Vb. Braginsky et al., ENERGY-DISSIPATION IN THE PENDULUM MODE OF THE TEST MASS SUSPENSION OF A GRAVITATIONAL-WAVE ANTENNA, Physics letters. A, 218(3-6), 1996, pp. 164-166
The results of measurements of the relaxation time of an all-fused sil
ica massive pendulum are presented. The relaxation time obtained was a
pproximate to 3 years, which corresponds to a quality factor Q = 1 x 1
0(8).
