Abstract
Abstract This is a detector wherein a dynamic mass quadrupole arrangement includes two parallel conducting charged plates capable of movement relative to each other. The arrangement is coupled to a dynamic gravitational force gradient having a characteristic frequency, the coupling occurring through a dynamic stressenergy-momentum tensor in the quadrupole arrangement. A bridgeservo amplifier electro-dynamical circuit resonant at the characteristic frequency is coupled to the plates for providing an output signal.
