Description
The authors have recently completed a series of tests on a newly developed superconducting gravity gradiometer consisting of two 400 g niobium proof masses separated by a distance of 15 cm. The resonance frequency of the proof mass suspension systems is 25 Hz. The sensitivity of this gradiometer obtained during these tests was 1 to 2 Eotvos Hz /SUP -1/2/ (1 Eotvos = 10-9 s-2 = 1 E) below 1 Hz, and 0.2 E Hz /SUP -1/2/ between 15 and 20 Hz. Using this gradiometer, a prototype experiment has been performed to demonstrate a new source-independent null test of the inverse square law of gravitation. Results are given
