In a near Earth orbit the driving force of a possible violation of the equivalence principle is a factor 500 larger than it is on the ground. A passive attenuator allows one to reduce the high acceleration noise of the space structure, hence to perform the experiment in a non-dedicated, non-drag-free spacecraft. By means of piezoelectric rotating sensors, with frictionless diamagnetic bearings, it is possible to test the equivalence principle at room temperature to 3 x 10(-15), about three orders of magnitude better than achieved so far.

Abstract
In a near Earth orbit the driving force of a possible violation of the equivalence principle is a factor 500 larger than it is on the ground. A passive attenuator allows one to reduce the high acceleration noise of the space structure, hence to perform the experiment in a non-dedicated, non-drag-free spacecraft. By means of piezoelectric rotating sensors, with frictionless diamagnetic bearings, it is possible to test the equivalence principle at room temperature to 3 x 10(-15), about three orders of magnitude better than achieved so far.File in questo prodotto:
