GGG: results from first
generation prototype (I)
Relative displacements (X,Y) between the centers
of mass of the test cylinders at zero
spin rate, 8 sec natural periods of differential oscillations.
The amplitudes of these
oscillations are slowly decreasing with time; data sets taken at subsequent times -under no
changes in the system- yield Q@1590. Residual air pressure during this measurement is of 2×10-5 mbar.
