ON THE SIGNIFICANCE OF ELECTRICAL DAMPING IN TORSION BALANCE

A typical electrical damping circuit for increasing the damping coeffi cient of a torsion balance system in high vacuum is discussed in detai l. Theoretical analysis and numerical estimation performed with typica l experimental parameters show that the signal-noise ratio can be impr oved by partial cooling of the electrical damping circuit. This is sig nificant for the torsion balance experiments.
