Cryogenic Gravity Meter.
Abstract
The report describes a cryogenic gravity meter which has a theoretical sensitivity of about 25 millimicrogal. The instrument consists of two parts--a suspension unit and a detection module. There are nine other units of power supplies, amplifiers, and other circuits as accessories for the operation of the instrument. The suspension unit is a cylindrically symmetric superconducting magnet with a large magnetic field and a small magnetic field gradient at the center of the instrument. The detection module is a double Josephson's junction magnetometer, also known as SQUID, which detects the magnetic flux change due to the motion of the hollow sphere. (Author)
